Rick,
The car was built to run hard. The quick change was mandatory, as well as the inboard brakes. The brakes haven't been a problem, we planned for that, but we didn't really think the rear end would heat up this much.
Personally I don't like cross drilled rotors. Under hard racing conditions each "hole" has a tendancy to spider crack. Got a pair of brand new BAER's, crossdrilled I'll sell you cheap!
I'd like to know more about the pump you are talking about. Any ideas where to look?
