The 350/370z club is a great place to hunt for widebody FD wheels.

 

wow thats really neat. the only thing is i dont know the offset. and I've been looking threw all the pages and they have so many different numbers.

 

I had this sitting on my desk top.
Online Wheel & Tyre Fitment calculator. Offset, Tyre stretch and Rolling Radius calculator
maybe doesn't apply,but it is Neat!..lol!

 

I bought some RE Amemiya AW7 original specs was 17x8.5 +22 & 17x9 +22 I had it redone & stepped lip to 18x11 18x9.5 3in lips all around. I'll shoot u some pics this Thurs. when I pick em up.

 

check out RIMTUCK.com - Wheel Fitment Database

enter your car, wheel sizes, and it'll bring up other people who have done the same setup and you can get an idea of what kind of fitment you are looking for. if you find what you like on stock fenders just subtract 25 from the offset (i'd recommend 20, aftermarket fenders arent always 100% on size)

 

Lots of sites out that can help with that just make you get it right cause if not you be going through wheel bearings about every few months or so! Good luck!
