Default Correct Wheel Offset for 91 C4

I am sure there are many discussion about the correct fitting. I am looking to purchase a set of Ruf 17" for my 91 C4. Anyone knows if this fits despite the owner had it on his Cab:

Sizes are: 17X9X6.5, Rear are 17X10 et56.7. Tires are 235/45/17 and 255/40/17.

Thank you,

The wheel offset requirements are the same for all narrow body 964's. They should fit ok on your car if they fit ok on the previous owner's 964.

Judging by the looks of the bottom pic, the fronts poke too much. The offset is stamped on the back, I would ask for that. It seems a little fishy he's listing the offset on the rears and not the front, like maybe he doesn't want people know?


As a general rule, 9's on the front of a NB are not ideal.

Good point. I didn't focus on the width of the front wheel. 9 inches is most likely too wide.

RUF made rear wheels in both 17x9 and 17x10. This looks like a set of rears and rears, not fronts and rears.

Default RUF on 964

Agree with Spartansix, Remember the C4 requires the front and rear wheels to be close in circumference.

That's a lot of tyre on the front. I run 225/45 17" on 7" wide rim on my C4 and that's plenty.
