This is the Build Thread for 2017 Shelby GT350R HR892. Reply below.

And I agree that it would be a shame to have to replace a Carbon Wheel. However.............I purchase track insurance every outing, so somewhat covered and as well, I putchased a full set of Carbon Take Offs .... all 4 for about the same price as one, so I do have spares.

I want to thank everyone on this thread for their input. I have multiple track days on multiple sets of Sport Cup 2's and pretty much have reached their limit of adhesion and I don't want to mod the motor or add power, just looking for that next "advantage" and figured that tires are the...
