Dirt oval setup help

[cmain]

This year I am going to run electric dirt oval sprint cars for the first time. Any advice on what order to do setup changes?
In 2wd off-road I generally started with tires then ride height after that shock oils ect. Is this the same in oval?

Maybe some of the setup gurus could help with these scenarios.

1. If you car is loose entering the corner check these things...

2. If your car is loose on exit of the corner check these things...

3. If your car pushes entering the corner check these things...

4. If your car pushes exiting the corner check these things...

Any help is appreciated

Thanks
Mark

make the shock longer on the RF to tighten it up everywhere, move collar down or add more spacers. Do the opposite if its tight, but this will make it looser but snappy loose if you go too far.

RR-- make it longer to loosen up the car and visa versa

LR-- make longer to make it tighter and visa versa you can add weight to the extreme LR of the car to tighten up also

LF-- Shorter shock to make it turn in better or ((loosen it up on entry))

I ahve no clue what shock oils will do for ya, but this is just a short thing you can do. I have learned that if you make an adjustment on one corner (LF) you need to make the opposite adjusment on the oppsoite corner (RF)

Good info thanks. I never even tought of shock length this oval stuff is going to be interesting

you can do infinite things. shock oils are going to make the car do certian things on entry and exit. the shocj length will make the car loose or tight all the way around. dfferent springs will do the same thing also. Best thing to do, is take a notepad and just do different things, and keep notes. look at lap times and how easy it is to drive.

this is off of the Bumps and Jumps website...I use it and it works well:

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.
