hey everyone. I'm new to this whole forum thing. im sure its been talked about, but I'm wondering what size rim and offset id need for a preferably 315 tire in the rear. I have a 1998 trans am with completely stock suspension and would like to go with 17 inch wheels. all help would be greatly appreciated

All in that thread dude...

"17"x11" Wheels

ZR-1 Style for Camaro +50 mm (Known as Grand Sport offset)
ZR-1 Style fo Firebird +36 or +50 mm The wheel well on the "bird" is a little wider.

American Racing TT-2's +45 mm

With 17"x11"s there is always a possibility of needing the BFH and/or fender rolling mods with 315s. If lowered, an Adjustable Panhard Bar becomes a virtual necessity. Some have used the +38 offsets with an 11" wheel but it does stick outside the fender and is definitly not recommended on lowered vehicles. +50 and +56 are the two most common. +50 is the better fit (for the ZR-1 replica).

For road race only applications a 17"x11" at all four corners can be made to fit."

If you don't have a watts link you will need to do a little hammering to the inner fenders so they don't rub. Wouldn't hurt to roll the outer fender lip either.

FYI Im running OEwheels 17x11 Zr1s with 315/35/17s on my car (with a fays2 watts link) and got no rub under normal street driving and got a slight rub on the inner fenders under hard cornering during auto-x. You will definitely rub without a watts link.
