KONI QUALITY AND TECHNOLOGY ARE THE KEYS TO THE PERFORMANCE OF YOUR CAR’S SUSPENSION

REBOUND DAMPINGThe primary function of rebound damping is to control or slow down the undesirable oscil-lations of the spring or torque tube. Rebound damping controls the transitional roll or lean as the vehicle enters a corner.

It should not be used to try and contain the total roll of the vehicle, but it will control how fast this roll occurs. Remember, spring rates, sway bars, roll centers and ride heights are all determining factors in roll control.

Rebound adjustment is a very effective tool to optimize the car’s balance front to rear. It should be noted that too much rebound control on either end of the vehicle will cause an initial loss of lateral acceleration (cornering grip) resulting in too much understeer or oversteer when entering the turn.

We hope you find these tips useful at the track. Remember, there is always plenty of horsepower lurking in the chassis, and it does not necessarily come from the engine. See more tuning tips on page 19.

Truechoice KONI Racing Services is pleased to help with your Koni Shock Absorber needs, whether it be new shocks, rebuilds, restoration or advice on how to get the most from your car’s suspension. Call us today at the toll-free number listed below.

KONI shock absorbers have a reputation for high performance. In order to main-tain that reputation, Koni relies on quality, in both technological design and manu-facture, to assure their shocks achieve and maintain their performance. All through the KONI manufacturing process is evidence of quality; produced from the finest materials, surfaces are machined to the narrowest tolerances, strict quality-control standards are incorporated in all production steps, at the end of the production line every single damper is 100% dyno-tested to assure optimum performance.

THE IMPORTANCE OF CORRECT DAMPING...KONI’SANSWER IS ADVANCED TECHNOLOGYShock absorbers are the heart of any car’s suspension. They are often the most neglected component when it comes to performance tuning. KONI recognizes that every vehicle has unique damping needs, and for that reason they offer shocks with three different technologies in order to offer a system that is the perfect solution to an individual racing application.

It is vital that the damping rate of the shock absorber be in har-mony with the spring rate and unsprung mass of the vehicle and then tuned to the current track conditions.

Every KONI is adjustable for ultimate performance benefits, and the adjustability feature of Koni shocks makes this vital tuning a simple procedure if a few simple guidelines are fol-lowed.

BUMP DAMPINGThe bump damping controls the unsprung weight of the vehicle (wheels, axles, hub carriers, etc.). It controls the upward move-ment of the suspension when hitting a bump in the track or under braking. It should not be used to control the downward movement of the vehicle when it encounters dips (this is a func-tion of the spring).

Also, bump damping should not be used to control roll or bottoming. Generally, the ideal bump setting is achieved when walking or side hop in a corner is at a minimum and traction and ride feel the best.

WHY THE 2812? HERE ARE 10 GOOD REASONS FROM SOME OF OUR CUSTOMERS:•BetterDriverFeel•EasytoUse•WideRangeofAdjustment•No“Hateful”BumpCanister•ExcellentReliability and Repeatability•MoreStability

In modern racing applications damper sensitivity, reliability, repeatability and ease of use are a must. The design and operation of the 28 series racing dampers is unique proof of KONI’s reputation as the leader in the field of damper technology. The 2812 series are specifically designed for these purposes and have proven track records in Formula One, Indy Car, Sportscars, Vintage Cars and many others. They are specifically designed for competition purposes and offer full adjustability while fitted to the car. Their precision adjustment mechanisms allow for maximum control possible over the damping forces generated.

The 28 series damper achieves this by utilizing an advanced design cartridge that controls the opening and closing of valve loaded ports. Positive lock detents assure that that each port can only be open or closed. The result is the cartridges will always accurately reproduce a set of eight pre-determined damping curves. Various bump and rebound cartridges are available, each with their own characteristics.

A pair of cartridges is housed in the main piston, one for bump, one for rebound. Together they can modify any given basic valving in 64 different ways. By having all forces generated by the piston assembly, the control of the damper over the suspension is instant and precise, decisive and smooth. A separate bulky reservoir is not needed and the installation can be kept simple, compact, lightweight and clean.

Drivers like the 28 series because they feel a real difference between adjustment steps. Mechanics and race engineers appreciate the user friendliness and apparent “simplicity” of the dampers that make them so easy to work with.

2812 MK II RACING DAMPERNever a company to leave well enough alone, KONI introduced the latest member of its 28 Series family of racing dampers, the 2812 MK II, after sensing that it already had a good design in the original 2812 package. KONI went looking for ways to make incremental improvements on the original and three design areas were attacked — weight, friction, and precision. The results show the goal was met! Lighter weight materials were used throughout the shock with durability maintained. The friction challenge was met by using state-of-the-art composite materials in key internal components. Precision was improved through splined, rather than keyed, mechanisms. In all, a much-improved step forward from the already great 2812.

KONI SPA1 TECHNOLOGY FOR THE DRAG RACERThe KONI Drag Racing Shock Absorber Series SPA1 has long been the mainstay on the professional circuit due to their unique technology in both single- and double-adjustable damper technology.

KONI surpasses the old 90/10 theory.

The KONI SPA1 series of drag-racing-only shock absorbers is a complete departure from the old “90/10” theory which is no longer valid to the modern drag racing competitor. The old thinking was to have the vehicle’s front end rise quickly and stay there to promote as much weight transfer as possible to the rear wheels. This was achieved by virtually no damper rebound forces (10) and a great deal of bump force (90). The theory was to hold the front suspension up to maintain that “bite” to the rear tires. Problem was, the high front end destroyed any attempt at proper aerodynamics and E.T.’s suffered as a result.

The KONI SPA1 series of drag racing shocks re-write the old theory in several ways. First, there is virtually no bump (compression) damping, allow-ing the front end to settle quicker and restoring the proper nose-down attitude that is essential for clean air flow over the car. Second, the rebound (extension) forces are made velocity sensitive, meaning the forces increase at a rate directly proportionate to the shock’s piston speed.

On a dry surface with good hookup, the amount of lift generated by initial launch is very sudden and quite violent. The velocity sensitive KONI SPA1 reacts instantly to dampen this lift, avoiding bogging caused by too much weight transfer. It is all accomplished by good shock design, proper tuning and KONI’s fresh look at old theories.

In another condition, a slick surface would provide less lift and tire shock, so the SPA1 then allows more movement of the front end since the lack of initial traction does not lift the chassis as violently. This gentle impulse does not activate the higher speed circuit of the SPA1 valving, and allows more front to rear weight transfer resulting in better bite. SPA1 drag shocks have five settings that enable you to tune your chassis for the best front to rear weight transfer.

For KONI rear SPA1 shocks the new technology has brought about a big difference. The rear shock now has nearly zero bump (compression) damping, but the rebound damping is now digressive. This means they are designed to de-gress, or “blow off,” at high piston speeds. This prevents the possibility of grossly over-dampening the rear suspension on initial launch which would pick up the rear wheels causing a loss of traction. The rear SPA1 KONI will “blow off” and then allow proper unwinding of the rear suspension.

BUMP STOPSSince racing dampers are usually required to limit the travel of the suspension, all KONI racing dampers come supplied with a specially-designed cellular polyurethane bump stop. This provides safe and controlled bottoming of the suspension as well as preventing internal damage within the damper from metal-to-metal contact. Between races it is good practice to inspect the bump rubbers. If they show signs of deterioration, they should be replaced.

Bump Stop Graph A = load at damper mount when car bottoms without a bump stop

B = force required to keep car from bottoming

Combining technology from the world’s leading manufacturers of suspension components, along with years of racing-bred suspension knowledge, Truechoice KONI Racing Services has developed a Suspension Solution for all phases of street, sport and competition driving. What racing background? How about the hot GrandAm Koni Challenge Series as our ultimate proving ground, and a host of happy winners contesting many SCCA and vintage race car competitions, with cars utilizing Truechoice KONI Racing Services, KONI shock and Eibach spring technology. We do stand by our performance record!

There are many considerations to evaluate when choosing a performance package for a street-based car. To help your decision of how radical a suspension modification you should make based upon what type of driving and or racing you will be performing, Truechoice Suspension Solutions are broken down into different phases. Each phase is based on the best components for that level of performance and acts as a starting point from which you can build into the next phase if desired.

Standard Koni Sport shocks are backed by Koni’s Factory warranty. In most cases, Koni Sport shocks can be rebuilt and revalved at Truechoice KONI Racing Services. Our factory-trained technicians and suspension specialists have the knowledge and the expertise to ensure that you arrive at the best solution for the level of performance you are seeking for your car.

KONI Sport Shocks are designed for aggressive driving while continuing to offer driving comfort. The KONI Sport Shocks are manufactured to act as an upgrade unit for many stock applications. All of the KONI Sport Shocks offer adjustability in rebound and some models offer adjustability in both bump compression and rebound.

Eibach Pro-Kit and Sportline performance springs are designed to improve the looks and handling of production cars. Pro-Kit springs are designed to lower cars anywhere from .75” to 1.5”, to provide the ultimate balance of comfort and handling. Sportline springs offer an increased drop from 1.5” to 2”, or as low as you can safely go on a street car, adding an aggressive level of ride comfort and handling.

The KONI 8041 RACE series dampers are designed as a bolt-in application for those running either in high performance driving events, road racing or autocross. They are externally adjustable in rebound damping and can be adjusted on the car. They are designed to work with the extreme high-perfor-mance spring rates up to 1000 lbs. with coil-over sleeve setups. These shocks come with factory style perches but will also work with Koni coil-over sleeve systems seen elsewhere in this catalog.

Also, these shocks have been shortened to give additional travel in the suspension to work with the lowered ride heights. This gives the dampers additional travel and keeps the car from bottoming out. The measurement given in the table below is the amount the shocks are made compared with the factory length dampers.

SUGGESTED ADJUSTMENT PROCEDURE FOR ROAD COURSE USEADJUSTING THE BUMP DAMPING CONTROLBump damping controls the unsprung weight of the vehicle (wheels, axles, etc.) It controls the upward movement of the suspension as when hitting a bump in the track. It should not be used to control downward movement of the vehicle when it encounters dips. Also, it should not be used to control roll or bottoming.Depending on the vehicle, the ideal bump setting can occur at any point within the adjustment range. This setting will be reached when “side-hop” or “walking” in a bumpy turn is minimal and the ride is not uncomfortably harsh. At any point other than this ideal setting, the ‘side-hopping’ condition will be more pronounced and the ride may be too harsh.STEP 1: Set all four dampers on minimum bump and minimum rebound settings.STEP 2: Drive one or two laps to get the feel of the car. NOTE: When driving the car during the bump adjustment phase, disregard body lean or roll and concentrate solely on how the car feels over bumps. Also, try to notice if the car “walks” or “side-hops” on a rough turn.STEP 3: Increase bump adjustment clockwise 3 clicks on all four dampers. Drive the car one or two laps. Repeat Step 3 until a point is reached where the car starts to feel hard over bumpy surfaces.STEP 4: Back off the bump adjustment two clicks. The bump control is now set. NOTE: The back off point will probably be reached sooner on one end of the ve-hicle than the other. If this occurs, keep increasing the bump on the soft end until it, too, feels hard. Then back it off 2 clicks. The bump control is now set.

ADJUSTING THE REBOUND DAMPING CONTROLOnce you have found what you feel to be the best bump setting on all four wheels, you are now ready to proceed with adjusting the rebound. The primary function of rebound damping is to control or slow down the undesirable oscillations of the spring or torque tube. The rebound damping controls the transitional roll (lean) as when entering a turn.

It should be noted that too much rebound on either end of the vehicle will cause an initial loss of lateral acceleration (cornering power) at that end which will cause the vehicle to oversteer or understeer excessively when entering a turn. It does not limit the total amount of roll; it does limit how fast this total roll angle is achieved. How much the vehicle actually leans is determined by other things such as spring rate, sway bars, roll center heights, etc.

Too much rebound control in relation to spring rate will cause a condition known as “jacking down.” This is a condition where, after hitting a bump and compress-ing the spring, the damper does not allow the spring to return to a neutral position before the next bump is encountered. This repeats with each subsequent bump until the car is actually lowered onto the bump stops. Contact with the bump stops causes a drastic increase in roll stiffness. If this condition occurs on the front, the car will understeer; if it occurs on the rear, the car will oversteer.

STEP 1: With the rebound set on full soft and the bump control set from your testing, drive the car one or two laps. Paying attention to how the car rolls when entering a turn.

STEP 2: Increase rebound damping three sweeps on all four dampers and drive the car one or two laps. Repeat Step 2 until the car enters the turns smoothly (no drastic attitude changes) and without leaning excessively. Any increase in the rebound stiff-ness beyond this point is unnecessary and may in fact be detrimental.

EXCEPTION: It may be desirable to have a car that assumes an oversteering or un-dersteering attitude when entering a turn. This preference, of course, will vary from one driver to another depending on individual driving style.

ROAD RACING/AUTOCROSS SHOCK ADJUSTMENT TROUBLE SHOOTING GUIDEThe following is a guide to try to fix handling problems AFTER the car’s initial setup has already been found.

FRONT: REBOUND

Setting is too firm - Can cause the car to “jack down” which can cause the driver to think the car is too firm in compression. Can also cause a lack in grip from the tire not separating from the chassis fast enough and cause the car to understeer. Setting is too soft - Though a soft rebound setting will allow better compliance with the road, the car may feel floaty or excessively oscillate after hitting bumps.

FRONT: COMPRESSION

Setting is too firm - Can cause the car to feel skittish and lose grip over rough sections of pavement. Can cause outside tire to be loaded too quickly. The car won’t stabilize in a turn. Setting is to Soft - Can cause a corner entry understeer. Can possibly cause excessive suspension movement.

REAR: REBOUND

Setting is too firm - Can cause a snap over steer on corner entry from rear tires losing contact on bumps. Can also cause the car to “jack down” in the rear and lose grip. Setting is too soft - Can cause a corner entry oversteer and corner exit oversteer. Vehicle may feel floaty or excessively oscillate after hitting bumps.

REAR: COMPRESSION

Setting is too firm - Can cause the car to have a snap oversteer, especially on mid-corner bumps. Car won’t feel stable in turn and skittish on rough pavement. Setting is too soft - Can cause corner exit understeer and possible excessive suspension movement.

SHOCK ADJUSTMENT TROU-BLESHOOTING GUIDE NOTES:1.When changing to firmer springs, the shocks usually need to be set firmer for rebound and softer for compression damping

2. On rainy or slick tracks, softening the compression damping will help to delay initial loading on the tire which increases grip.

This is a guide for Shock Setup only. Other factors such as the spring rates, sway bars, alignement and tire pressures will also have an affect on thr han-dling of the vehicle.

SUSPENSION WORKSHEETSHOCK SETUP TECH TIP SHOCK SETUP TECH TIP SHOCK SETUP TECH TIP SHOCK SETUP TECH TIP

Suspension WorksheetIn order to determine a basic spring setup, two important inputs are required: WHEEL RATE and SUSPENSION FREQUENCY.

In order to determine WHEEL RATE and SUSPENSION FREQUENCY, you must first determine MOTION RATIO. A different formula is needed for the type of suspension your race vehicle utilizes, A-arm or Beam axle. See Step 1. Please take into consideration the ANGLE CORRECTION FACTOR (shown in step 1) in your computation.

WHEEL RATE is the actual rate of a spring acting at the tire contact patch. This value is measured in lbs./in., just as spring rate is determined by using the formula below. See Step 2.

SUSPENSION FREQUENCY refers to the number of ciliations or “cycles” of the suspension over a fixed time period when a load is applied to a vehicle. See step 3.

Step 1: Motion Ratio

Step 2: Wheel Rate (Non-beam)

A-arm Suspension (See Diagram 1)MR Motion Rationd1 Distance from spring center line to control arm inner pivot center (in.)d2 Distance from outer ball joint to control arm inner pivot center (in.)

Beam Axle Suspension (See Diagram 2)MR Motion Rationd3 Distance between spring center lines (in.)d2 Distance between tire center lines (in.)

Tip 2: Calculation of Spring Rate Needed for a Given Wheel Rate

C Spring Rate (lbs./in.)WR Wheel Rate (lbs./in.)MR Motion RationACF Angle Correction Factor

Diagram 1 (A-arm Suspension)The motion Ratio is a lever arm effect of the control arm acting on the spring. If the spring is mounted at an angle, the reduced motion of the spring must also be taken into account.

Diagram 2 (Beam Axle Suspension)The motion Ratio of a live axle setup is shown here. Over two-wheel bumps, the motion ratio is 1:1. Over single-wheel bumps and during body roll, the motion ratio is as shown in Step 1. The motion ratio is only used for calculating roll resistance, not for suspension frequencies.

Let’s start with suspension coils on the winning car at every Indianapo-lis 500—since 1964. Beyond that, champions of Formula One, CART, IRL, NASCAR, Endurance Sports Cars, Off-Road, Grass Roots Oval Track (dirt and asphalt), along with a wide variety of others, have ben-efited from the proven Performance Advantage found in every Hyperco product.

With today’s racing environment more demanding than ever before, no one component can be less than perfect. The demands on suspension coils have reached a peak with today’s modern suspension technol-ogy. Hyperco is the one manufac-turer, known around the world, as the company that devotes the neces-sary resources and the one-to-one customer service needed to produce the optimum suspension coils that will meet the highest demands of today’s winning race teams.

Properly engineered and manufactured suspension coils will not lose free length or installed height under normal racing conditions. At Hyperco, our focus is always on innovation. Always researching. Always developing. Testing new ways to improve performance. In fact, we’re not just coiling springs, we’re engineering suspension coils, along with other components that ultimately offer racers our Performance Advantage.

While other companies offer springs as a part of their expanding product line, Hyperco’s focus is on high performance suspension coils. We recognize that the balance and the handling of any race car must be at its optimum for winning results. That’s why we’re dedicated to being the source, world wide, for high performance suspension coils. Customers can be assured we are not distracted by other products; trying to be all things to all people. Our team of specialists continu-ally work to realize a component that is at its absolute state-of-the-art potential for every application and environment. We continue to combine the finest engineers and craftsmen with the latest manufacturing technology in the industry. We utilize the latest in design and performance simulation software, along with multi axis rate and load testing equipment to measure overall dynamic performance.

What’s more, Hyperco manufactures from materials that are not found in a mill’s standard inventory. This allows our engineers to design suspension coils to optimum specifications with the largest variety of wire diameters available today. We also manufacture from a wide variety of materials including ultra high tensile chrome silicon, micro alloys, titanium, alloy steels and stainless. Multiple magnaflux inspections, before and after coiling, are used to ensure the wire is free from surface imperfections which, undetected, could lead to spring failure.

Collectively, this combination of professionals and resources affords Hyperco a versatile, innovative facility and, most importantly, it’s earned us the ability to offer the racing world consistent performance, exclusive technological advance-ments and reliability. What’s more, from coil-over and conventionals to specialty and custom, Hyperco also works with race teams one-to-one, to develop custom and proprietary products. As a result, more and more teams are benefiting from the Performance Advantage found only with Hyperco suspension coils.

That’s why Hyperco is the world wide leader in high performance suspension coils and related components.
