Ok i recently purchased a 1982 Pontiac...I dunno if its a lemans or bonneville...i do know its a metric chassis..and is identical to a monte except the point in the front of the hood...anyhow...

the cage was professionally built and is in....the whole body is skinned...from rocket to door...new firewall made behind seat and goes into trunk...

I have some questions about setting up the car..

It came with the stock rims on it with whatever size 15" tire on it..

I have to run an 8" wide rim..i will probably run bassets...bead locks on LR, RR, and RF...what size offset should i run on the car???

Also i seen some guys in my class (pro stock)...run a tire on just the RF that has about 1" less of offset so it sticks out??? what is the point in that??

The car came with 3 shims in the RF upper control arm...going buy the ole snap on level camber guage its about 2.5 degrees.

Our track is about a 1/3 mile....with decent banking...THe car has afcos on it but im not sure what spring rates...

ALSO...what is staggar and how do i measure it?

Ok here is where i get confused....you say an 88 and a 90 per say...this is out of our rule books

Hoosier Racing Tires on All Four corners of race car.
8/84-15 D30
8/87-15 D30

does that mean i can either run a 84 or an 87??? should i put 87's on the right side and 84s on the left side???

I am totally new to this any help is appreciated...i need to find a book to help me out! LOL.

also what about tire pressures????

why only the LR an 84....what benefit would you get by putting the 84 on the front with a spacer?

Ok suppose your track goes black slick before the main. You trade the 84 on the LR for the 87 on the LF. You install an inch of spacer between the LR hub and the wheel. Now your car will transfer more weight to the RR and pick up some side bite. It will also handle better in the apex.
Now you are thinking "Why don't I run this way all the time?" Well When the track is tacky you want to really balst your way into the turn, set the car and stand on it! When the track is slick you have to "finess" your way into the turn and feather the throttle on the way out. If you run this set up on a tacky track, as you power your way in you will probably push until the car finally turns and then the rear will break loose and you will be loose on the way out of the corner. Then you will be asking,"I have this monster motor and everyone is passing me and I can't get hooked up? Why is dat!"
