WTB: 15" wheels for the RX7........

[SCCA MX5]

Im looking for a WIDE set of wheels to put slicks on the RX-7.

bolt pattern is 4x114.3
Looking for 15" wheels. Rears need to be between 9" to 10.5" wide, with around a 4.5" backspace. (4" is fine, 5" might rub...)

I really only need the two rear wheels, since my current fronts are 15x8, but if there is a used set of four (hopefully staggered width) let me know.

I would prefer to have some old Epsilons, Simmons, work, etc... (some good looking OG wheels)
but I would consider Diamond racing, Aero, etc...

If anyone knows of a good deal on any new or used wheels, let me know...

I could also do a 13", 14", or 16" wheel, but 15" is ideal...

Thanks!
