Drag Racing Setup

STEP 1:

Prior to testing make certain that the wheelie bars are raised as high as possible while maintaining control and eliminating their influence as much as possible on damper settings.

STEP 2:

Place all damping controls on minimum. Make a pass in first and second gears in order to determine that the car goes straight. If not the alignment, tire pressure, etc. should be corrected before proceeding any further.

Pay close attention to what occurs during gear change. If the car wheelstands or violently proceed to step 3 and then to step 4. However, if there is rear tire shake, wheel hop or excessive body separation proceed first to Step 4 and then to Step 3.

STEP 3: FRONT DAMPER ADJUSTMENT PROCEDURE

Pay close attention to what is happening to the front end during launch and the first gear change. Your goal is to eliminate all jerking and/or bouncing movements so as to obtain smooth transitions at all times.

Too Light of a damper setting allows violent chassis separation and may even result in jerking the front wheels off the ground during initial launch. Too light a setting allows the car, during gear change to bounce off its front rebound travel limiter and then bottom out in a continually oscillating manner.

Too Firm of a damper setting will prevent the tires from easily lifting off the ground and thus providing sufficient weight transfer. During a gear change a firm setting will also cause the chassis to bounce off the tire when the chassis settles down.

Adjust the damper by increasing the rebound damping in 1/4 turn (90 degree) increments until a smooth transition from launch through gear change has been achieved. If double adjustable KONI's are used, adjust the bump damping in three click increments to control the amount and the rate at which your front end settles during gear change. Watch your ET's and your times start to get slower back off the rebound adjustment by 1/4 turn and the bump adjustments by 2 clicks.

STEP 4: REAR DAMPER ADJUSTMENT PROCEDURE

Pay close attention to the rear of the car as your goal is to dampen the tire movements as firm as track conditions permit. Remember that the damper controls the amount and the rate of weight transfer to the tire.

Too Light of a damper setting allows excessive separation between the body and the tire.

Too Firm of a hamper setting allows high tire shock and causes extreme flattening of the tire.

Adjust the rear damper in 1/4 turn (90 degree) increments of rebound adjustment and if KONI double adjustable are used increase the bump adjuster by three clicks for each pass. Watch your ET's and if your times start to get slower reduce the amount of adjustment by 1/4 turn of rebound adjustment and 2 clicks of bump adjustment.

STEP 5:

When all adjustments have been completed reset your wheelie bars as low as possible without hurting your ET. Once you have completed this procedure only fine adjustments may be needed in the future due to varying track conditions.
