The Handling Guide

Directions: Do one of the following change to your vehicle at a time and drive test.
Keep good notes (It's hard to do at the track but try to keep a log it really helps).
Also, don't forget to have fun....

Phase 1 (going into the turn)

If the vehicle is loose at turn entry then..(needs more traction)

(1) Right front spring is to soft use a harder spring
(2) You need to add more crossweight - by adding a round to the right front spring (add weight to the left rear tire).
(3) Change left front spring to a softer spring.
(4) Lower chassis - keeping it level with the rear.
(5) Reduce front right caster (no less than 2 degree min.)

OR If the vehicle is pushing into the trun entry then..

(1) Right front spring needs to be softer.
(2) You need to reduce the crossweight - by taking out a round to the right front spring (add weight to the front left tire)
(3) Increasing right rear spring tension by one round
(4) Increase front right caster (6 degrees max.)

Phase 2 (the middle of the turn)

If the vehicle is loose in the middle of the turn then...(needs more traction)

(1) Increasing the crossweight by adding a round to the front right and left rear evenly (add weight to the left rear tire)
(2) Use a harder spring to the left rear
(3) The right rear spring needs to be decrease a round (less spring tension)

OR If the vehicle pushes in the middle of the turn then...(needs more steering)

(1) Decrease crossweight by taking out a round to the front right and left rear evenly
(2) Use a softer spring to the right rear
(3) The right rear spring needs to be increase a round (more spring tension)

Phase 3 (coming out of the turn..)

If the vehicle is loose coming out of the turn then..(needs more traction)

(1) Stagger needs to be decreased on the right side
(2) Increase crossweight by adding a round of spring tension to the right front and left rear evenly (add weight to the left rear tire)
(3) Check if right rear spring tension is to much - if it is then take a round out of spring.
(4) Decrease rear springs evenly to the right and left rear.
(5) Use a soft tire in the rear

OR If the vehicle pushes coming out of the turn then...(needs more steering)

(1) Stagger needs to be increased on the right side if present.
(2) Decrease crossweight by reducing a round of spring tension to the right front and left rear evenly (add weight to the front left tire)
(3) Increase right rear spring tension a round.
(4) Increase rear springs evenly to the right and left rear.


This might help?

Thumbs up Clay Banked

It sounds like it may not be set up but maybe an issue with the diff or drivetrain that only shows up later on in the evening as the traction in the clay comes up .
I would go thru your diff and drivetrain first before messing with you set up ?
