Lightweight 18" wheels (lighter than RPF1's)

I don't trust RPF1's for excessive track duty. I've seen a lot fail or crack over time when beat on. People run them because they're light, cheap, and replacable when one does fail.

I have a few friends that have broken quite a few RPFs. We've switched to NT-03Ms as they're a bit stronger, almost as light, and cost about the same. Either way, track wheels are pretty much a consumable anyway and should be retired after a bit of use.

Well I ended up buying them. I got an amazing deal on these, $300 plus shipping, because the guy I bought them from had them on his NSX which he just used in promotional videos for Superspeed, so he didn't even use the wheels anymore.

Superspeed RF03RR in titanium finish
18x8.5 +35 front, weight 18.3lbs
18x9.5 +38 rear, weight 18.9lbs

They are made to clear big brakes, but these still barely clear the sport akebonos on the G, it's only a few mm but it's just enough.

Tires are Michelin Pilot Sport 4S 235/45/18 and 255/40/18. I will probably get wider tires when it's time for them to be replaced, but for now I'm using my old tire setup from my stock sport wheels.

I know I need a drop. I'm planning to go with 370z pre-2016 nismo springs to drop it about .5", I'm not interested in going much lower. Now onto some pics!
