I'm helping a friend get into racing, he has a mustang mini-stock and I have no clue on spring selection or anything(I run open wheels) We are running on a 1/4 mile dirt track in Alabama. His suspension has to remain stock, we can change springs and shocks but no jack bolts or such. It has struts on the front. I need a starting setup. What spring rates to run??? He has to run a 7" wheel w/ DOT tires. What PSI in the tires??? Any help would be greatly appreciated. Thank You.

Steve Smith Autosports has a book dedicated to the third generation Mustang as you described. I have not yet read it but all the books I own from him are GREAT! There was a load of great info in the old Pony Stock/Mini Stock Racing Technology book and I would guess the new one would be just as much a value. I have just ordered my copy.

I ran a 1/4 mile for a while and a 175 RR and a 225 LR with stock front springs and struts and stock shocks seemed to work good
I ran tire pressures at
RF 20
RR 20
LF 15
LR 17
Different drivers like different setups though

Im fairly new to the racing thing but ill give you an idea what to do for loose and tight situations.If you run weight jacks and your car is loose add weight to the rr or add bigger rr tire.If you are pushing add weight to the rf or add bigger tire to rf,keep in mind you can add or take away from all the corners to get where you want to be i usually just mess with the right side so i dont chase the handling around to much.If anyone can add to this please do as i am still learning this also, or if i have it wrong please get me streightened out.

well adding a bigger RR tire (aka stagger) will not help a loose condition it will make it worse. And putting more bite on the RF tire will make the push worse in MOST cases.

I run 700lf, 750rf, 200lr, 250rr springs on a high bank. I would try 600lf and rf 200lr and 175rr to start with on the springs. Get as much negative camber as you can on the right front. The way the front end is made you'll gain positive camber in the corners so you have to compensate then adjust camber by tire heat. Good luck.

TAY did you post the rear springs backwards. If you put a stiffer to the inside when a car is already tight it would be worse.
