Question
our track
we have a ford fusion modified 4 cyl. stock car, with a 2.3l 318hp engine. we race on friday nights at the local speedway that is a 1/4 mile asphalt oval. we race from april-sept., were air temps go from low 70s, to low 90s in the summer! what setup would you use to get off the corners, & bring the car home to victory lane? i have included a blueprint of the track so you can see the angles, banking, ect. for the best setup you think would be for the track. also, you may want to know the track is very old, so it has cracks, & bumps in it.
AnswerOK The first time you wrote you mentioned an offset chassis. I have no experience with offsets.
For a regular FWD chassis, I would start with about 1/8" toe out, then RF negative camber of about 4 Deg. and LF positive camber of about 2 Deg. Rear toe should be dead straight, RR camber about 1 1/2 Deg. negative, and LR of about 1 1/2 Deg positive. Sway bars front AND rear with about a 1" dia. solid bar in front, and about a 5/8" or 3/4" tubular in rear. Make the rear bar adjustable and you will be able to reduce or increase oversteer to suit your driver by altering stiffness.
Do a coil over conversion in the front and use adjustable shocks front an rear. you want to adjust for maximum rebound in the rear, and maximum bump in the front. this will work to reduce dive under heavy braking .
All that will get you into the corner, and get you through it in decent shape. The ONLY thing that is going to get you OUT of the corner is traction. That requires proper tires, proper pressures, and a limited slip differential. There are no substitutes. pay the money and go racing .
Good luck
