I've seen some of you running 18's on your 951s. I found some 18x8 and 18x10 wheels from a '99 993 (did they stil make 993's in '99?). Would they fit on my '87? Don't you put like 305's on a 10" wide wheel? I've never seen anyone running rubber that wide.

You should check the front wheels and ensure that the hub opening will fit on your car. Some, possibly all, of the late 996 wheels are machined differently for the hub and will not fit on the fronts of 944s. But if that is the case, and you are willing to deal with the hassle, you can get by with using a thin spacer, 1/4" or so to get them to fit.

I would use a 285/30 on a 10" rim.

I run a 265 on a 10 inch rim and it works fine. The only reason I ran that narrow was because the front tires are only 225 and I HATE understeer.

265's came on the 18x10's in 99-01 on the 996 from Porsche. MY 02+ 996's came with 285's on the 18x10's. The wheels are the same but the suspension set up and geometry were different on 99-01 vs. 02+ cars that is why the change in rubber size. Both tires sizes work well on the 18x10 rims. You will find that the tire choices are much greater in the 265 size. Both are expensive.

Yea I run 265 on my rear 18x10 also but Im getting a slight rub on the passenger side when the car squats durring hard accleleration or if I have a passenger.

Danny - please check the size of the fronts to be sure. I also have a set of 7.5 and 10.0 x18 hollowspoke twists which were from a 1999 996. OEM tires were 225 and 265 and I have replaced with Dunlop SSRs in the same size with great results, so far.

danny951

The guy says they are from a 993 actually, and '99 993. Did they make the 993's in 99 still?

Oddjob

No, the last 993s were in '98. If they are the 993 Turbo Twist style, then you should not have the issue I mentioned about the hub center not fitting.

But check the rear offsets, there are two factory 10" wheels, one for the Turbo (et 40) and one for the narrow body (et 65). I dont think the et 40 will fit, the et 65 will.

I just picked up a set of 993T rims 8x18 front 10x18 rear so glad to see this thread. Did you guys need to use spacers for the fitment? thanks

DDP

Are you running the BBS LM reps? That is what I have and I have not noticed any rubbing issues yet. But I only drove it for 2 days.

Corleone

I have the BBS Le Mans 9+11x18" and they fit perfect. No problems at all. I have Kumho R 285/30 back and 265/35 in front

Tb311

Yea those are the ones I have. It drives fine but it only rubs when I acclerate real hard or go over a pretty big dip or bump. And if theres a passenger in the car it rubs a lot more easier. Its only on the passenger side only which has got me stumped on how I should deal with this problem . It seems like the passenger side sticks out more than the driver side. Maybe running 255s would fix the problem.

Here are the hollow spoke Technology (aka, Turbo Twist) wheels on my S2 in 7.5 and 10.0x18. You must use the 65 offset rears. I run 225/40 and 265/35 tires, but I believe the 285/30 will also fit in the rear.

THAT is awesome! Best looking wheels I've seen yet, and those are huge! Did you upgrade the suspension or are you still stock? And what pray tell, is that extra pipe beside the exhaust? I've seen something similar on a 935 and that was a seriously fast car...

Corleone

Thanks! I have a Cup suspension with -2 degrees camber at front. I have not lower the car max because of the risk to have the exhaust or something touching the ground.

The small pipe of 2.1/4" is directly from the wastegate so there is no restriction when the wastegate opens (1bar) and helps backpressure a lot when you really need. The sound when the wastegate is open between 1-1,5 bar is like a motorcycle, I love it...!
