edit: SOLD
I bought these from Motoextreme with the plan to powdercoat them flat black but another option has come up that I'm going to go with instead. I believe they have about 700 miles on them (Adam please correct me if I'm wrong), and they look new. These are the rims that come on the the Nismo 370Z. They have "Nismo" imprinted on one spoke.
These are wider than the sport rims, they should work with anything from 245 to 275 in the front and anywhere from 275 to 305 (maybe even 315) in the rear.
Specs:
19x9.5+40
19x10.5+23
They also sit 13mm further out from the sport rims front and rear, so the fit would be roughly similar to the sport 19's with 15mm spacers. They are also very light at 20.7 lbs. front, 23.0 lbs. rear according to my scale.
Asking $1500 OBO shipped to the 48 states. Paypal only. Center caps are included, but not shown in the pics. I temporarily removed them since I was going to get the wheels powdercoated.
Speaking of powdercoat - I have a source that will powdercoat for $60/wheel, which is a really good price. They do good work, my winter wheels are the base 18's powdercoated flat black and the PC is holding up great (except where the carwash scraped one of them, but that's another story). If the buyer wants I can get them powdercoated prior to shipping for my cost, which is lower than what many others are paying in other areas. You would be responsible for painting the center caps to match, or you could leave them silver, or leave them off.
Nismo Rays 19x9.5 (Front) weight = 20.7 lbs.
