I have Enkei on both my Z and Acura.
I wouldn't say that they don't make wide wheels because my Z's rear lip is about 4 inches.

 

I have RPF1's (search and see photos of my car). I really like them. They are as light as it gets unless you want to go to actual mags. Enkei probably makes more alloy wheels than anyone worldwide. The quality is outstanding. What's not to like? Enkei Racing series wheels are among the very finest available at ANY cost. You can spend more, but I doubt you can buy a higher quality (round, true, straight, balanced), lighter, or stronger wheel.
