Gen 1 997 GT3 wheels on Gen 2

[codieskid]

Hi all

I am currently actively searching for either a 997 Gen 2 C2S or C4S. While waiting for the right car I've been looking at wheels as I absolutely love the gen 1 GT3 wheels and wondered would they fit a Gen 2 C2S or C4S.

After doing some looking online I've found the wheel sizes are:
Gen 1 GT3 - Front 8.5Jx19 Rear 12Jx19
Gen C2S & C4S - Front 8Jx19 Rear 11Jx19

I guess the fronts will be fine but will the rears fit OK and is there any difference between either the C2S or C4S that would cause fitment issues of these wheels?

Any help would be much appreciated

Thanks

Yes, different offsets on 2wd vs 4wd.

So I am assuming that I will buy a 997.2 C4S for the argument of calculating fitment. If so I'd look to get a set of 997.1 GT3 RS wheels and have looked at the sizes and offsets

997.1 GT3 RS wheels
Front - 8.5J x19 ET53
Rear - 12Jx19 ET51

997.2 C4S wheels
Front - 8Jx19 ET57
Rear - 11Jx19 ET51

Assuming I were to replace the standard wheels with GT3 RS wheels then I calculate that taking into account the offsets the front wheels will sit 2mm further out of the wheel arches and the rears around 13mm. Does that sound about right? If so then I guess the RS wheels will fit fine

Thanks
