For anyone that is interested we have a email from a team that did an enduro on the Toyo RR last weekend at Autobahn. The RR was run for 4.5 hours and did very well !!! The car was a NASA 944Spec.
if not, remember that Phil's and Trackspeed offer the 15x6" D-Force CR6 wheels specifically for ITB etc.. cars that require that wheel width, allowing use of the SM6, RR, BFG, goodyear, as well as better avaialbility even from the guys who do make 14's.
I remembered this thread from last year, and wondered if anyone had used these yet. Any word on how they stack up against other options performance-wise?
