True BBS Wheels?
 

I am looking at changing out my 15" wheels for 17s. I have what I believe are true BBS wheels. By my measurements 9X15 front and 11X15 backs running 225/50 front and yes 345/35 rear. I would like to go a little more narrow with more tire options. http://forums.pelicanparts.com/uploa...1236354064.jpg

If your question is "Are your wheels BBS wheels" the answer is yes though those widths aren't commonly seen in that wheel design.

E30 centers would be the correct centers for the 911. Those centers are usually seen on 951 models.

I have a set of those exact wheels for a Speedster. They are BBS Motorsport racing wheels, 20 bolts and you can get inner/outers up to 17" diameter. There are some of that style center that requires wheel specific lug nuts.

Nice wheels! While you've got them off the car could you measure the backspace and frontspace of the wheels? I'm curious what the specs of those wheels are.

Thanks!

Thanks for the info.You wouldn't happen to know where I could get inner/outers?
