DAMPING...KONI’SANSWER IS ADVANCED TECHNOLOGY Shock 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 REBOUND DAMPING and then tuned to the current track conditions.

1 SUSPENSION - KONI SHOCKS 2812 MK II KONI RACING DAMPER 28 SERIES Never a company to leave well enough alone, KONI introduced the latest SHOCKS member of its 28 Series family of racing dampers, the 2812 MK II, after In modern racing applications damper sensitivity, reliability, repeatability sensing that it already had a good design in the original 2812 package. and ease of use are a must. The design and operation of the 28 series KONI went looking for ways to make incremental improvements on the racing dampers is unique proof of KONI’s reputation as the leader in the original and three design areas were attacked — weight, friction, and field of damper technology. The 2812 series are specifically designed for precision. The results show the goal was met! Lighter weight materials these purposes and have proven track records in Formula One, Indy Car, were used throughout the shock with durability maintained. The friction Sportscars, Vintage Cars and many others. They are specifically designed challenge was met by using state-of-the-art composite materials in key for competition purposes and offer full adjustability while fitted to the car. Their precision adjustment mechanisms allow for maximum control internal components. Precision was improved through splined, rather than possible over the damping forces generated. keyed, mechanisms. In all, a much-improved step forward from the already great 2812. The 28 series damper achieves this by utilizing an advanced design cartridge that controls the opening and closing of valve loaded ports. FEATURES Positive lock detents assure that that each port can only be open or • Teflon® coated cylinder wall closed. The result is the cartridges will always accurately reproduce a set of eight pre-determined damping curves.

PDQ MOUNTING EYE - FOR THE 3012/11 SERIES The PDQ eye is an alternate fixing device made for the 3012/11 range of damper. With the advent of the PDQ eye, it is no longer necessary to remove the damper from the car to adjust bump damping. In this design, the piston rod does not thread directly into the eye the way it normally does; rather it is threaded into a disk which is able to rotate freely within the body of the eye. This option is available for all new 3012 dampers and can be retro fitted onto any existing 3012 already in service. An essential add-on for quick bump adjustments. Ideal for short practice sessions to get the most out of the handling. Part # KONPDQ 4 KONI SHOCKS - SUSPENSION 8211 SERIES TWIN TUBE HYDRAULIC The 8211 series is identical to the 8212, except it has a nickel-plated steel body, which adds a little weight, but offers identical performance.

Problem Part # KON12-9000SPA11 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 2812 SERIES LONG BODY proportionate to the shock’s piston speed.

SPA1 reacts instantly to dampen this lift, avoiding Part # KON2812SPA 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. 8212 SERIES ALUMINUM BODIED For KONI rear SPA1 shocks the new technology SPA1 DRAG RACING SHOCK has brought about a big difference.

19 PERFORMANCE SUSPENSION KITS

KONI Threaded Suspension Kits include four KONI Sport-valved struts and/or shocks featuring threaded, adjustable, lower spring perches (where applicable) and progressive rate, lowering springs designed for performance street driving. The kits are engineered in a joint effort with KONI divisions in Holland, Germany, and North America. Testing of the kits was done on the famed, high-speed German Autobahns. These kits were designed to give the vehicle a preferred ride height of 1.5” to 2.0” below stock, but the threading range allows the owner to make the ride height considerably higher or lower. Addi- tionally, the car can be run low in the summer and then raised for winter driving. It is always recom- mended that the kits be installed with bump rubbers because the threaded range of perch adjustment may allow the vehicle to sit low enough (for show or display purposes) to risk bottoming the shock’s internal parts without them. Also, care should be taken in setting ride height so as to not allow over- sized rims and tires to rub on the car’s inner fender, etc. Make/ Lowering Up To: Kit Model Year Front Rear Number ACURA Integra (exc.Type R) 1994-01 H, E, G H, E, G KON1150-5006-1 Adjustable spring perch.

In order to determine a basic spring setup, two important inputs are required: WHEEL RATE and SUSPENSION Step 3: Suspension Frequency FREQUENCY. In order to determine WHEEL RATE and SUSPENSION Suspension Frequency FREQUENCY, you must first determineMOTION RATIO. SF Suspension Frequency (cpm) A different formula is needed for the type of suspension your WR Wheel Rate (lbs./in.) race vehicle utilizes, A-arm or Beam axle. See Step 1. Please Sprung Vehicle corner weight take into consideration the ANGLE CORRECTION FACTOR Weight less unsprung weight (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

A-arm Suspension (See Diagram 1) MR Motion Ration d1 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.) Diagram 1 (A-arm Suspension) Beam Axle Suspension (See Diagram 2) The motion Ratio is a lever arm effect of the control arm acting on the MR Motion Ration spring. If the spring is mounted at an angle, the reduced motion of the d3 Distance between spring center lines (in.) spring must also be taken into account. d2 Distance between tire center lines (in.)

Over single-wheel bumps and MR Motion Ration during body roll, the motion ratio is as shown in Step 1. The motion ACF Angle Correction Factor ratio is only used for calculating roll resistance, not for suspension frequencies.
