Ricky,

This is the set up that Jeff suggested as a starting spot for paved tracks:

A Good Place To Start For Asphalt:



Caster camber settings
Left Front: Caster: + 2.5°     Camber: +2.5°  (top of tire tipped out)

Right Front:  Caster: +4.5°       Camber:  -4.0°  (top of tire tipped in)
1/16” toe out
Springs:
Left front - 225  Right front - 275
Left rear  - 185   Right rear - 200

 

Ride Heights:

Left front - 3.5”     Right front - 3.75”
Left rear  - 4.0”     Right rear - 4.25”

 

Scale Numbers:

 

Cross Weight 56% with driver.

Rear weight 52% with driver maximum.

Left side weight 52% with driver maximum.

Total 1300lbs with driver minimum.

 

Recommended Air Pressure:

 

Left front - 17psi   Right front - 27psi

Left rear  - 17psi    Right rear  - 27psi 

 

Rear End:

 

Keep rear end square to rear main cross member at all times.  Set this before you check the wheelbase and make adjustments to wheelbase with front suspension.

Keep the rear end centered in the chassis.

 

Notes: Round of wedge into the left rear and out of the right rear will tighten car. Reverse to loosen car.

The same for air pres. to tighten or loosen the car- air into the left rear will tighten ect.
