CORRECTING FRONT TWEAK – STEP 1: SHOCK PRELOAD
Determine if the FRONT of the car is tweaked by checking at the REAR of the car.
Correct front suspension tweak by adjusting preload on the REAR shock springs.
1. Lift and drop the front and rear ends of the car a few cm’s to let the suspension settle.
2. Place a pointed tool underneath the REAR end of the chassis at its middle point, and lift the rear
end. If one REAR wheel lifts before the other, the FRONT end of the car is tweaked from the front
shock preload settings.
3. Adjust the preload on the FRONT springs until both rear wheels lift at the same time.
Increase the preload on the FRONT spring diagonally across from the REAR wheel that lifted fi rst,
and decrease the preload on the other rear spring.
Adjust both front springs in equal but opposite directions, otherwise you will change the front ride
height.
Example:
If the rear right wheel lifts fi rst, INCREASE the preload on the front left spring, and
DECREASE the preload on the front right spring by an equal but opposite amount.
CORRECTING FRONT TWEAK – STEP 2: ANTI-ROLL BAR
After you have corrected front tweak by adjusting shock spring preload, reattach the front anti-roll
bar, re-check rear tweak, and correct it by adjusting the eccentric adjustor.
4. Reconnect the front anti-roll bar.
5. Place a pointed tool underneath the REAR end of the chassis at its middle point, and lift the rear
end. If one REAR wheel lifts before the other, the FRONT end of the car is tweaked from the front
anti-roll bar.
6. Loosen the lower setscrews in the left and right front anti-roll bar mounts. Adjust one or both
eccentric cams until both rear wheels lift from at the same time. Re-tighten the setscrew(s) to
secure the adjusting cam(s).
