Thats not what im looking for....

 

Look into Enkei NT03 9.5 +27 front and 10.5 +30 rear. Lightweight , strong and proper offset for wide tires.

 

10.5 +15 = 18x8.5 +33 just a wider wheel. A 10.5 +30 is in too far in and might hit suspension.

With a 10.5 +15 you gain an inch on each side of then wheel and maintain factory offset +\- 3 mm... You said your looking for lightweight track wheels with factory offset? Do you math and evenly compensate for wider wheels. To maintain factory spec offsets.

 

You have it reversed. Less numerical value offset, means centerline shifted towards the outside. A 10.5 +15 would be 1 inch wider on the outside and another half inch closer to the outside. What you're describing is a 10.5 +45. A 10.5 +30 would simply add an inch to the outside, or be equivalent to an 8.5 +30 with a 25mm spacer, for a net of +5. The offset spec is also static, it's the value that relates most with suspension geometry, where the face of the wheel/tire sits in relation to the fender is largely for aesthetic purposes.

With that said, one can find wheels with an offset that will maintain the factory look is retained by selecting the right width and offset to place the face of wheel/tire in the same location as OEM, but a wider wheel will need higher offset, and a narrower wheel will require a lower offset, both which effect the location of the wheel centerline relative to the suspension components.

 

Already answered above me, but 10.5 +30 adds an inch of wheel on the inside and outside. Keep proper geometry and trust me, it will not rub. Running a true coilover (springs mounted on the rear shocks= less clearance) this setup is nowhere close to rubbing. I own a set of RPF1's and NT03's, the NT03's fit perfectly and have the proper offset for the car, this allows you to run big rubber on them if you want.

 

Evo X MR have forged BBS OE wheels in 18x8.5 with a bolt pattern 5x114.3 and hub bore of 67.1 and 38 offset... they are realitively lightweight for OE forged wheel and since nissan bore is 66.1, they will fit.

you can pick up a used set no tire for 1k ish. i think would be a decent alternative to the OE Track wheel circa 03-04

 

Im more then likely going to end up getting the track wheels...
