I got a set of 17" Ruf Speedline wheel sized 9JX17 ET 17,7 Front and 10JX17 ET -5 rear with 225/45 ZR 17 and 275/35 ZR 17 tyres.

All images of these wheels on the 930 look like they will not clear the rear arches when lowered or going to a larger size tire.

Does anybody have any experience with a set of these?

What are the best tire size combinations? Any advice very welcome

I have the same wheels on my Ruf BTR, you might need to go with these, rears are 265/40/17 and clear with no problem. Hope this helps.

You're gonna be close on a regular 930, and no on a factory slant bc of the oil lines and brake vent, not to mention the left front wheel well which has an indentation for the washer and are tough to clear on a lowered car.

Here is picture of front Ruf Speedline 17/9 225/45/17 and my rear with Ruf Speedline 17/10 with 265/40/17.

Thanks for the pictures! I am using the Elephant racing second oil cooler in the left front wheel that requires to relocate the washer bottle and in the rear I got the high clearance oil lines so that should not be a problem. Do you use any spacers on these?

I'm getting a Pat Williams EFI 3.4 engine done so I need some meat in the back for 500+ rw hp !!

Dirk, isn't the rear 10" wheel a +5, not -5, offset?

In any case, Speed and BTR, are these wheels designed to run with or without the factory [28mm?] spacer?
