I've got a 99 Carrera C2 Coupe and i'm looking at buying a new set of alloys for it, fancied a set of 'Work Rezax II'

Any body know what size i can fit without rolling the arches.

If i did need to roll the arches how much work is involved ??

Porsche specs 17" and 18" wheels for the MY99 Carrera in matched sets.

The front fenders are rolled from the factory. Tires sizes spec will veery with wheel sizes.

17" Porsche spec wheels:

Front: 7 x 17 offset 50/55 mm

Rear: 9 x 17 offset 55 mm

18" Porsche spec wheels:

Front: 7.5 x 18 offset 50 mm

Rear: 10 x 18 offset 65 mm

or

Front: 8 x 18 offset 50/52 mm

Rear: 10 x 18 offset 65 mm

or

Front: 8 x 18 offset 50/52 mm

Rear: 11 x 18 offset 63 mm

Only a couple of tire brands will fit the last option (11" rears) without rubbing.

On my 996 C2 I installed 18x10's 54mm offset with 285/30's will just barely clear the fender lip without rolling it. When I first got the wheels, I didn't think they were going to clear, especially with my H&R springs. I removed the strut on one side, bolted the wheel/tire back on, and lowered the jack to let the suspension swing up through it's arc. Turns out it clears by something like an 1/8 of an inch.

On my 99C4 i went up to a 19x8 in the front and a 19x9 in the back with no issues at all. I believe they are a 32mm offset if i'm not mistaken

Loren,

From this info you posted earlier, are these the rim sizes and offsets for all narrow body 996's. ie: C2, C2 Cab, Targa - MY '99 thru '04

Cheers for advice,

decided on 18" to go with H+R springs i bought few months back, what does the offset mean is it the centre of the wheel compared to the outer rim also what is the ET measurement.

Offset is explained very well here

Would the Mich Pilot Sports happen to be one of the tires that would fit without rubbing?

Also what tire size would be best for those wheels? (Front: 8 x 18 offset 50/52 mm Rear: 11 x 18 offset 63 mm)

Thanks!

-Shawn

I've looked throught the forums but still can't find where the wheel/tire size FAQ is posted? Sorry to be a pain. :S

I'm asking because it sure seems like there are more 19" wheels availible than there is 18" and I'd like to see what tires would work for my '99 C2 assuming a 19" wheel.

Curious on offset for the RUF wheels. since the front 8.5 is larger does the wheel use a wider or skinnyer tire and do you know what TPMS option is??

Front 18" x 8.5" 58mm varies for application TPMS option available

Rear 18" x 10" 66mm varies for application TPMS option available
