The original wheels were in 17x8 and 17x9 and for the 964 I believe. If you look for "Das Ruf-Rad für die Carrera 2/4 Generation" you should find the original advertising materials.

Ok, thank you for the posts.. I just picked up the rims and took some detailed photos of the markings on the front and back. They have been powder coated so some of the writing is not as clear as if they only had paint.

Three Wheelin'
Ruf wheels are heavy to begin with, running a wider rim than the tire requires is just pointless dead weight. That setup is for posing, not performance. Additionally, the photo appears to show cuts into the edge of the tread from rubbing.
Personally, I use a front 7.5" et49 and a 225 tire. That's as much as I can get away with at rs height without rubbing inside or out while keeping the smaller steering stops for the best turn radius. Rear is 9" et32 with a 255 tire. There is about 15-20mm still available before rubbing the inside oil line. So there is room for a 275 tire, if you could find one and have 10" wheel with the correspondingly necessary offset.

Well, I finally got around to bolting them on... they still have the continental tyres from the previous owner, but before buying new boots, I wanted to check for rubbing etc.
The front tyres on mine are 225 45 17.. and at total full left lock, I get a little scrubbing... It seems to depend on the attitude of the car.. ie, on flat level or not, but my 205 50 didn't do this... on full right I don't seem to get any scrubbing.
Wondering if it is safe to run a 5mm spacer on all 4 corners? This should help I imagine?

We just delivered this beautiful 964 to the owner over the weekend. Full suspension, wheels & tires upgrade plus few other OEM+ mods. We believe this RUF wheel is one of the most classy choice for 964. The result speaks for itself.
The centers were custom-matched to Slate Grey Metallic. Machined lips & silver logo on the center caps.

Respectfully disagree with the comment. Here are some weight info for you. hopefully it will get the fact straight.
Factory CUP 1 wheel:
Front 7/7.5x17 - 22.5lbs
Rear 9x17 - 26.3lbs
RUF wheel:
Front 8x17 - 22.7lbs
Rear 9x17 - 23.1lbs
The front is 0.2lbs heavier than stock wheel but it's half inch wider. the rear is 3.2lbs lighter than stock wheel at the same width. We run 225/45-17 & 255/40-17 N-spec Michelin tires with perfect result. There's no compromise in performance at all. Hope this clear some stereotype.

I also weighed my RUF’s before installing them and while they do weigh more than the D90’s they replaced they also are bigger and wider which had a profound affect on the cars handling.
