Porsche 997 turbo rims on Z?

03Z33

Shouldn't have any rubbing based on the sizes, it's actually really close to standard recommended fit for Z34.
Plenty of brake clearance since Porsche runs huge brakes and you'll be pushing the wheel out 25 mm further.
No problems running the adapters, people do it all the time. It's no different than any of the many people on this forum running bolt on spacers. The adapter is hub centric on both the Nissan side and the Porsche side. It'll include all the hardware, 12x1.25 open end lug nuts to secure the adapter to your car and 14x1.5 ball seat steel open end lug nuts to secure the Porsche wheel onto the adapter which is already hub centric 71.6 for Porsche.

You can buy some nicer black aluminum factory Porsche lug nuts (closed or open end) from a 993 or older Porsche if you prefer. I run the BBS Porsche lug nuts which are open end black aluminum.

No pics of my car until mid-September since it's off the road temporarily. I alternate between a few sets of wheels regularly but my most common setups are:

BBS CH-R Porsche (street/daily setup)
19x11.0 et31 & 245/40/19 Hankook V12 front
19x12.0 et20 & 275/35/19 Hankook V12 rear

Volk TE37 Porsche (track/drift setup)
19x9.5 et14 & 245/40/19 Advan Sport front
19x11.0 et19 & 275/35/19 Hankook V12 rear

Volk TE37 Porsche (track/grip setup)
19x11.0 et19 & 295/30/19 Toyo 888 all around

Volk TE37 Porsche (autocross setup)
19x11.0 et19 & 305/30/19 Hankook RS-3 all around

Also have my eye on a set of Techart Formula wheels... think they'd look pretty good once I get a bbk.
