Hey! I'm taking delivery of a kit next week! Built a roadster with one son 8-10 years ago, and now building a GTM with his younger brother. It'll have a lightly upgraded LS3 with a G9650. Lots of add ons from Shane, etc.

Question about the FF GTM wheels. In looking back over the million posts over the years it looks like everybody has 18" fronts and 19" rears with the FF wheels. They now have 19" x 9" wide fronts and 20" x 12" wide rears. Has anybody built with this combo yet? They also have some 18" fronts still. Do the 19s work ok on the front fender clearance? I assume there is plenty of room for the 20s on the rear? Even if you haven't built with the larger combo, I'd appreciate any feedback you have.

Many thanks
Butch
