Many variations in the coupe VS the roadster. Generally if FX track on both ends the standard wheels 9s and 10.5s will look small on the coupe. We run 9.5s and 11s with different offsets than the standard 24 and 27. If the rear is SN95 width the 10.5s will fit and look OK just not as much dish as the 11s in FX track. I have 9s and 10.5s for track tires and run a 1 inch spacer on the rear to fill the well. A 12 would fit on the rear.
In short the coupe is 1.25 inches wider per side on the front and about 2 inches wider per side on the rear. HTH, cheers Richard.
