Ok, so I've been searching the forums. Since there are so many questions and answers out there, it's hard to weed it all out and get what I'm looking for.

I've come to a rather interesting situation with my 1985 S2 that is presenting me with a challenge. I want to buy a set of wheels to fit the car and add some meat where it counts (on the ground).

Right now, I have 16x7" dish wheels with 225/50VR16 Dunlop 5000s on them. They are a standard 65mm offset as indicated on the wheel (not measured). On the rear there is a 25mm (could be 1") spacer. There is still room in the back for about a 10-15mm more as mounted currently.

I've measured the spacing dimensions to the mounting face and here they are:

Front Wheel (measured under second coil of spring from the bottom)- Front Spacing 50mm, Rear Spacing 265mm.

Rear Wheel (measured flush with inside of wheel well)- Front Spacing 121mm, Rear Spacing 262mm.

I'm thinking 17x9" in the front and 17x10" to 17x12" in the back would be about right. The problem is, I can't seem to work the numbers to find out how much offset there should be. If I'm doing it right, I'll need about 80mm of offset in the front to keep the wheel inside the fender.

HELP!

mark k has those numbers, ive seen them posted here before with 9.5" front and up to 11" rear (with minor fender rolling). perhaps the 10" rear is a better choice as it keeps things simple in obtaining rubber to fit - or is that with an 18" rim? you could check the rear offset on late model porsche 18" x 10" wheels which others have been fitting without issue.

The specs in my sig will fit without any fender rolling whatsoever. And it will require that you have a custom 3-piece wheel made since no one stocks 928-specific wheels (..at least ones with the correct offsets for use with maximum tire widths).

Or, you may get lucky and someone may have a used set they want to sell.
