    Hi, I am a new owner of a 1991 348 TS. I am looking to replace the wheels and need the specs for 18" offset.

    Need info on the following for 18" offset. I would like to go 8.5 fronts and 10.5 rears. What are the offsets? Car is not lowered, don't want the rims to stick out of the top fender. Thanks

    PS** im not stuck on the width, please recommend away if you think I need to go wider in back or thinner in front...

    If you change the wheel width you have to do some math. There's also about a 30 mm variant in the rear and 11mm in front depending on what you prefer. There is no "one number".

    Perhaps look for challenge wheel sizes and their offset? It's close to what your saying. Plenty of wheel threads out here.

    Check the vendor section as well one vendor has aftermarket challenge wheels in the exact size you're saying if I recall.

    Good luck and have fun.
