Title: Base Line Set Up For Dirt
Post by: brads2cl on May 16, 2012, 10:49:27 pm

I've read through most all of the setup handling pages without a definitive answer on what a good baseline setup would be. To give an idea I will be be running 1/4 1/3 and 4/10 mile oval dirt tracks in pennsylvania with medium banking. Whats a good baseline setup to start with. Please include caster, camber, ride heights, cross, left side, front, etc... As much detail as you're willing to give. Just pretend this is a brand new race car that your setting up for the first run out. Any help on this topic would be great.

I like a neutral car, so my cross is usually 50-50.5%
52 left % and 52 rear %

Springs:
165   185
170  150
Swap the rear springs if you want a looser car.

Tire pressures, assuming you have a beadlock:
10   12
10   9

Camber:
+3  -5

The more caster split you have, the more the car will turn to the left, so that depends on your driving style.
I usually run a 4-5 degree split as I am more of a bottom feeder and keep the car pretty straight.

Very easy to drive, tune to your liking/driving style.

Path Valley, Lincoln, Susquehanna, Trail ways. 6x is my number. I have only been out to 2 shows this season and I haven't scaled the car or anything just getting used to driving it. I noticed that guys were running super low air pressures on the left side, they look like drag slicks somewhere in the realm of 4 psi in the LF and about 6 in the LR.

So If you do set the car up in a manner that the left is shorter than the right side wheel base, Is the rear still "square" in the end. I've been dirt track racing go karts since I was 12 and learned a decent amount about tires and what not, But I just have no idea where to start with these cars. Also by making the front a arms even with the cross member are you talking about in a ride height manner so its level strait across or angle front to back. One question I would really like to see answered is, If you bought a brand new legend car and took it home to your shop to scale it for the first time. What is the sequence of things you would be doing??? A numbered list with the ending percentages on the scales would be pretty sweet.

Always start with the rearend square to the frame and adjust any lead with the front suspension.  I usually put about 1/4" lead in the right front but if you are straight up it wont hurt anything.  Jim's setup is a really good starting spot and will get you in the right direction.
