I know this has been discussed but looking for a specific answer, and the posts out there are contradicting each other. I have a 99 C2 w/ 17 inch wheels, and would like to put Victor Equipment "Zehn" 18'. Per Victor Equipments web site (see below) this is what should fit. But after looking at an offset calculator, it looks like this would not fit (link below)???? Can any one help/explain.

Thank You!

911 Carrera 1998-2004 996

Zehn 18x8 (ET45) 18x11 (ET55)

Front: 235/35/18

Rear: 285/30/18

I am looking at GT3 replica wheels in 18 x 8.5 ET52 and 18 x 10 ET 54 will these work on 2001 C2?

Thanks for the help.

The rears will not without spacers. See the acceptable offsets above for narrow body cars.

I hate to disagree with Loren, who is the resident expert and has incredible knowledge of these cars, but spacers won't help on the rears. spaces decrease the offset and the wheels you are looking at have too low an offset now. The higher the offset the farther in the wheels moves, and spacers move the wheel out. I know this from experinece having once bought a set of wheels with to low an offset that rubbed on the fenders. spacers that move the wheel out would only have amde the problem worse. Go to 1010tires.com, they have a wheel offset calculator. You can enter the standard wheels/width/offset and then the same info on any wheels you are considering and it will show you how much the wheels move in each direction.

If I understand the 2 answers Loren thinks I should add 10mm spacers to move my wheel towards the ouside of the car. Dharn 55 you think I am going to be already too far out and they will rub.

Planning on using the 285/18s that give the proper rolling circumference. Sorry if I'm not well versed but 10mm is a little more than 3/8" is it that tight?

Thanks again

Steve

You can go here and plug in your OEM widths and offsets and then your "new" wheels to see the impact. Spacers will move the wheel out - also if you go to a bigger tire remember that half the increase will move the tire out even further.
