ional 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 nd 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.

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 nest 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.

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 th

4 e spring rate and unsprung mass of the
e spring rate and unsprung mass of the vehicle and then tuned to the current track conditions. Every KONI is adjustable for ultimate performance benets, and the adjustability feature of Koni shocks makes this vital tuning a simple procedure if a few simple guidelines are fol - lowed. BUMP DAMPING The 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. SUSPENSION - KONI SHOCKS 2 WHY THE 2812? HERE ARE 10 GOOD REASONS FROM SOME OF OUR CUSTOMERS: • Better • Easy • Wide • No • Excellent and Repeatability • More 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 eld of damper technology. The 2812 series are specically designed for these purposes and have proven track records in Formula One, Indy Car, Sportscars, Vintage Cars and many others. They are specically designed for competition purposes and offer full adjustability while tted 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.

RACING DAMPER Never 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 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 ow 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 s

ensitive 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 ve 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. 8212-1121 15 7/8” Max10 3/4” Min5 1/8” Stroke 8212-1123 19 1/2” Max12 1/2” Min7” Stroke 8212-1126 17 1/2” Max11 1/2” Min6” Stroke These are drag racing shocks only.

Racing coil-over shocks are specially calibrated for professional drag racing. It is recommended that you send in these shocks every season to determine if any adjustments are required. Bracket Racing If an SPA1 shock is not readily available, Truechoice KONI Racing Services can convert an existing KONI shock to SPA1 drag racing valving. TIP : Remember, ALL trailer miles add wear to your shock absorbers, and may cost valuable elapsed time on the track. Shocks should be serviced regularly.

BUMP STOPS Since 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 C = point of contact at the bump stop D = point of bottoming COIL-OVER SPRING CONVERSION KITS Many different types of coil-over set-ups can be acheived by using the vari - ety of hardware Truechoice KONI Racing Services has available.

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. 8041 RACE Series Shock Applications 19 PERFORMANCE SUSPENSION KITS SUGGESTED ADJUSTMENT PROCEDURE FOR ROAD COURSE USE ADJUSTING THE BUMP DAMPING CONTROL Bump 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. DAMPING CONTROL Once 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

21 damping controls the transitional roll (
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 GUIDE The following is a guide to try to x handling problems AFTER the car’s initial setup has already been found. FRONT: REBOUND Setting is too rm - Can cause the car to “jack down” which can cause the driver to think the car is too rm 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 oaty or excessively oscillate after hitting bumps. FRONT: COMPRESSION Setting is too rm - 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 rm - 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 oaty or excessively oscillate after hitting bumps. REAR: COMPRESSION Setting is too rm - 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 rmer springs, the shocks usually need to be set rmer 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.

Lowering Part #Front 24 SUSPENSION WORKSHEET SHOCK SETUP TECH TIP SHOCK SETUP TECH TIP SHOCK SETUP TECH TIP SHOCK SETUP TECH TIP Suspension Worksheet In 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 rst 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 xed time period when a load is applied to a vehicle. See step 3.
