18" WHEEL WIDTH

DOES ANYONE KNOW HOW WIDE OF A 18" WHEEL YOU CAN FIT ON AN 1986 944T. ALONG WITH THE BACK SPACINGSFOR FRONT AND REAR. I KNOW MY CAR HAS A DIFFRENT BACK SPACING THAN THE 87'-MODELS. NOW I HAVE THE FACTORY 16X7 & 16X8 PHONE DIALS. 
 
THANK YOU,

Hi, I have a 944 S2, not a turbo, but my 18" wheels are 8" front, 10" rear. These fill the wheel arches perfectly and I don't have any problems with them fouling the bodywork.
 
It depends on the offset of the wheel to know if you are gonna need spacers.
 
I hope this helps. What type/make of wheels are you thinking of fitting?

I WAS LOOKING AT A FEW DIFFRENT BRANDS AND TRYING TO DECIDE WHAT WIDTH I CAN USE ON THE 944T. I WANT TO GO AS WIDE AS POSSIBLE IN THE REAR AND STILL NOT HAVE TO WORRY ABOUT ANY RUBBING

10 inch width wheels will fit just fine under the rear arches without any fouling of the bodywork, but I would say that without body modifications thats the limit. You must get the offset right & you may have to use spacers.

You can get 11's to fit under the rear if you run a lot of negative camber.
