I need you guys running Sheridans or other wide body kits with 10"+ slicks to measure the distance from outer fender lip to outer fender lip, across the car. Basically how wide is your car?

For you V8 guys I need you to meaure the thickness of your adapter plates.

Wheel details on Bill's (now mine) car are in this thread. We measured ~70 width at the rear HPH Bontempi flares.

Brett:
71 inches, outside to outside. 12 1/2 inches from inner fender lip tov to fender well....HPH flares

The adapter plate is around 1".

(not our engine, but it will give you an idea.)

Thanks guys exactly what I was looking for.

My adapter plate measures .750 (3/4")

Welcome Bob! I'll add you to the "Non-Porsche Converson" list thread, link is my signature.
