Offset on an 8" wide front wheel for a 928 needs to be at least 57 and low to mid 60s are better for proper suspension geometry and handling.

Don't run 911 wheels with a 50-53 front offset on your 928.

Those twist wheels used to be sold by Tire Rack. They have unusually small lug nut holes and a regular lug nut/bolt socket doesn't fit them - you need a thin walled socket that doesn't have a wheel protection sleeve on it either.

 

Shameless hijack: More details please. Target > '88 S4

 

Exactly.

 

@Dylan_928 Does your car have spoilers (front and back)?

If not, I prefer the phone dials 16", not the 15" that comes with autos or 944s.

Mark Anderson may carry them.

If your '80 has spoilers, 17/18" would look good. 17" may be better.

 

These wheels belonged to Rob Edwards then BC. I need to take them off the car to get specs.

 

Rob could prolly tell you off the top of his head.

 

 

I think 17's and 18's look just as good (if not better) on cars without spoilers.
