18x8.5/18x11 on '99 C2
 

I have a line on a set of aftermarket GT3 wheels that are listed as 18 x 8.5 front and 18 x 11 rear. I don't yet know the offsets but will provide them. In general will these fit my stock '99 C2?

Thanks!

off sets are everything. if they are oem spec aftermarket off sets then yes they will and look great.

11 inch rear wheels will fit a narrow body? I thought the most you cold comfortable get in there were 10 inch.

I spoke with the seller. Offsets are ET 40 (Front) and ET 63 (Rear). I decided to pass as I plan to lower the car and don't care to roll the fenders.

This set seems like a pretty good deal if they are the right size for your car:

Thanks for everyone's input.

I mounted 8.5 w 50mm offset front, 11 w 64mm offset rear with no rubbing even with 19" wheels which added an extra inch to overall tire diameter on my 2004 C2

I have gt3 996 wheel on my narrow body car. lowered to gt3 specs on PSS10s and 5mm spacers. No issues or rubbing. OEM GT3 tire sizes.

If youre close go buy them.

Resale here on RL.

Someone will want these.

Just saw the link. 250.00 for four brand new?

I have the OEM 996.2 GT3 wheels with the same exact offsets front and rear and they fit perfect on my NB 996 cab. If the price is $250 for all 4, they are a bargain even aftermarket and used.

Thanks for all the responses to the thread, specifically application to the narrow body cars. I now know I have more options for wheels. I have the original solid turbo twist 17" wheels and I was thinking about going with 996.2 18" wheels. Unfortunately, Porsche made a bunch of different widths with a bunch of different offsets. It makes searching on the internet for used wheels a little tougher. I am sure there are other threads on the topic, as far as what widths and offsets will fit a narrow body car.

The below web site lists all years of Porsche's and a wheel fitment for various wheel dia and widths with their off-sets.

I have 18 x 8 and 18 x 11 Sport Technos on my C2. No issues.

What size tire on the 11" wheels? The stock size for the 10" wheels is 285/30/18.

Is your car lowered? Spacers? Rolled Fenders?

7mm spacers, PSS10s, aligned and lowered to 6gt3 specs. Narrow body. No rolled fenders no rubbing.

295 30 18 rear 235 40 18 front

The original owner on mine put 19" TechArt wheels. Looks amazing but the front tires do rub just slightly. No problems in the rear.
