Here's a testament to the B6.1D indoor clay setup I posted. Robert Black, OCRC owner got his new car built and after going to the "Coach" setup was racing for the win in 2wd Expert with lap times that made me jealous.
RB made a couple small changes, running MC Positron Front tires and V2 gray front springs. I also think he didn't run a front wing for the race. Please note that until the Schelle rear tower is out, you can get the same effect running long eyelets in the rear.
