first I searched and can't come up with anything.
I am looking to start tracking my Z ASAP, and am looking into 18x9-10.5 size wheels, I got a ne set of RE01R 265x35 18s to use. was thinking of the wonderful RPF-1s GTC-01 or work XD 9s... thoughts and opinions on the sizes that will fit or are recomended.
Thanks guys

 

I would use a set of RPF1's in 18x9.5 +15 IMO

 

I'm not looking up the offsets , but i know the RPF1's suck for track being +15. You need to stick as close as possible to +30. NT03's have the proper offsets, if you get the nice (flush offsets ) you will be highly limited in tire sizing.

 

265/35/18 is a good size to run on all 4 corners, for the track. I run it with the nismo wheels, 18x8.5 front, 18x9.5 rear. The offsets are not overly-aggressive, and they have no rubbing problems. The offsets are something like +.25 or +.30. The 18x9.5 size will probably work for all 4 corners, just don't get +.15 offsets. I agree with terrasmak, I would try for +.25 or +.30 offsets.

I do run +.22 offsets with my other set of wheels, but I had slight rubbing in the front with 265 width, until I added more negative camber with SPL a-arms, and rolled my rear fenders in the rear. (I think this was with 265/40 though, so maybe 265/35 would have been ok). In any case, avoid the dope super-low offsets.

 

I'm just about to order (today!!!!) a set of RPF1 in 17x9.5 +18 and planning on using 275/40/17 tires on them.
From what I have read, that should work with 3 degrees of negative camber up front. Hoping it works out OK!!!!!!!!!

 

I run XD9 18x9 in the front and 18x10 in the back, +30 offset all around.
Very happy with the wheels, suspension geometry and alignment all check like stock, but bear in mind they won't fit any sizable BBK with those offsets. They fit brembo comfortably enough though.

245 sits perfectly on 9", 275 on 10" is near perfect (sidewall can be sen very slightly angled, but we're talking less than peanuts, and this is with fk452, which run narrow).
on 10.5 you might find a wide 275 still sitting well, and a narrow one ever so slightly stretching.

265/35 R18 will be a bit short on the back, and might stretch a little bit on 10.5
Should still sit well on the front though if a bit on the pinchy side, and will be very close to factory recommended diameters if you get a 275/40 or 285/40 in the back.
Of course tracking you'd have VDC off, so I don't know how much you actually care about the diameter staggering, but if you have to drive it to the track with those on it could get annoying if you run square height.
