I just picked up a couple S5 'vert wheels for the front of my car to replace the stock S4 wheels I had up there. The S5 Turbo II wheels in the back I've had for a while (since I curbed the original

h: )
Anyway, the fronts where contract made by BBS for all the convertable FC's, they weigh 11.5 pounds. 15x6.5". The rears are license made BBS copies used on all 89-91 RX-7 Turbo II's. 16x7".
The goal was to have lightweight 15's in the front, besides the weight advantage I can also use cheaper tires on it. I wanted 16's in the back for the bigger meats. These look close enough to work, IMHO.

Fire away.
