I've started to narrow down my wheel selection, seems as if there are few wheels in the 5x100 hub that actually are available in the specs that FFR provides.

I do like the Enkei TS9s and the best combination I can find would be:
Front 17x8 +45
Rear 18x9.5 +40

So for the front the offset would push the wheel in 5mm more than desired leaving less room while turning.

Also, I like the Enkei PF07 (special order) and the best combination I can find for these would be:
Front 17x8 +38
Rear 18x9 +40

I'm building a coupe version and don't plan any drastic measures to fit different wheels other than maybe a set of rear trailing arms if needed. Is there a difference between the VCP arms and the eBay special arms? Also, thoughts on the above wheels? The TS9s would run ~900$ and the PFO7s ~1500$.
