i'm trying to get some information on the difference with clearance between a 996gt2 and 996tt. i'm trying to get a 12" rim to fit (19x12et51). I understand that the stock wheel is a 18x12et45, so i would have thought that if you space it out 6 mm it would be identically spaced. i also have a JIC cross coilover setup on the car.

any thoughts about whether such a wheel would fit? or what are the suspension differences that would effect clearance between a 996tt and a 996gt2?

thanks kindly.

Cheers,
Boris

Just get a set of Porsche OEM 5mm spacers. They come with longer lug bolts with red collars.

The wheels fit perfectly on the wide body 996 C4S, 996TT, 996 GT2. The offset with these spacers will be 46mm, which is ok.

What wheel would you run at the front ?

so you believe the rears will require a 5mm spacer?

Not required, but I would recommend you to stay as close as possible to the factory offsets, to let the suspension work as designed.

I use an offset 33 front wheel, but I also run 3 times stiffer springs on that axle, so I'm not concerned about additional suspension travel caused by the more aggressive offset.
