Hey Nick,
Was wondering about your square setup.... I am focusing on HPDE events as well and want to go to run 305's all the way around, switching wheels and tires for track days. I have seen several people running 11" wheels all the way around but having to use spacers and longer studs on the front. You were able to put 305's on the stock front wheel size ok?

Yes, for now I am running 305/30/19 on all 4 corners of my stock gt350 wheels. I have no problems with this even though I was initially worried with how wide the Supercar 3's are. The 305's are quite a bit wider than the stock PSS 305's and they looked massive compared to the 295 PSS's. But they fit without a problem and I have done a track weekend on them. They performed great and I plan on leaving them and continuing to run a square setup on my stock wheels even after I get the Apex wheels.
