Default Largest wheel that can fit on a 964? Am I missing something?

I have not been to the board in several months...

...when I was looking at wheels for mine, I had read that 18's were too large for our cars, but now (after being gone a while) I see more and more of you have 18" Porsche wheels on your 964's...

Am I missing something? Did that take any modifications?

Could I put 18" turbo twist or any other 18" OEM Porsche wheels on my 90 Targa?
How wide of a wheel/tire can fit on the front and rear?


Geezzzz, I have some catching up to do!
Like a NEWB all over again

The 18" are fine. I did 8x18 and 10x18, with ETs of 50 and 47. I put 225s on the front and 265 on rears. Perfect fit. No spacers or mods needed. This was for a 92 C2.

Porsche does not recommend it. (something about it being hard on the front hubs and bearings???)

Turbo Hubs IIRC are ok, Adrian Streather also had 19"'s on his, though there is a weight issue to take into account, most of us will never get close to the damage experienced by the racers which caused this to go out as a TB, so although YMMV I have 18's on mine and why should you worry??

Carrera Cup cars ran both 17" and 18" wheels during their race careers.
http://www.cupcar.net/92cup.asp
Wheels/Tires
Used 8x17" front and 9.5x17" rear one-piece Cup wheels
Used 8x18" front and 9.5x18" rear three-piece "Speedline for Porsche" wheels

Sizes/Offsets/OEM spacers/PN's have been discussed here in the past; a search should answer any questions.

Carrera Cup cars also run Turbo hub carriers. With that said, I would have no problem running 18" wheels on a standard street C2/C4/RSA.

Doesn't ride quality suffer a little. Maybe that's the wrong way to say it... Won't the ride be stiffer because of the thinner sidewall? Going from 16" rims to 18" would be quite a change I would think. I have 17"s on mine and the ride is a little stiff but I've also got a slightly modded suspension.
