Porsche 997 turbo rims on Z?

03Z33

Funny you ask, I'm running Porsche wheels on my Z too
You'll need two pairs of the H&R adapters and they'll bolt right on. You'll want to change the tire sizes though since Porsche tires are too short.
I'd run 225/45/19 or 245/40/19 fronts
285/35/19 or 305/30/19 rears

The front fittment will be a little weak, kind of how 15mm spacers look on the stock front wheels.
Rear will fit very nice with stock alignment, stock ride height or lowered on springs. Should come out a bit more if lowered on coilovers with some extra negative camber.

Your final offsets with the H&R 25mm spacer adapters will be:

19x8.5 et 31 front
19x11.0 et 26 rear

The only bummer is that the stagger is so extreme front to back... It would be better if the fronts where a bit wider since the Z really likes a bit more tire up front. It works well on the Porsche due to the rear engine/ rear weight bias.

Thanks heaps for the help mate!!
Do you have any pictures of the porsche rims on your Z? Which ones have you got?

So their will definitely be no rubbing on any suspension components with the wider rims on the back as long as you got those spacers right? The brakes were the other things I was worried about... will it clear sport brakes?

Is it dangerous to use those Hub Adapters or no problems? I heard it can cause vibrations?

Rep points for your help mate.
Any pics you have would really help me decide too!!

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.
