A friend gave me his wheels from a 996tt,The front are the same with CS 8,5x19 same offset with same tires 235-35-19.The rear wheels is the problem,
11x19 and the tires are 315-25-19 (offset 45),I know that is not right but what kind of spacers I need?

 

are you lowered?

 

Arent the offsets from 996tt to Cayman totally different? I would think that the 996TT wheels would stick out too far.

 

If you are going to put spacers more than 15mm on it, you might have chance to having rubbing issue.

 

for 11" wheels, you need +35 offset to clear shock. So a pair of 10mm spacers will work. But not sure 315 tires will clear.

 

Yes,I have techart springs.

 

I used to have lower springs, and I can tell you 325/25 19 with 15mm spacers wouldn't work. I'm not sure 315 though.

 

I think you'll be rubbin'... either with the springs or with your fender (even if you rolled them).

 

I was running 19x11 with a 315 tire in the rear on my Cayman S. Had rubbing issuses to the point that a rear blew out. Went down to a 295 in the rear. No rubbing.

 

Just curious, what's your offset?

 

19X8.5 +51 up front with 19X11 +38 in the rear, sits flush with no spacers. Lowered on Champion springs.

 

What size of spacers I ll need with 285-30-19x11 at the same wheel (45 offset).Is it ok a 9mm spacer?

 

Any Pictures?
