I have the MoVit BBK on the front axle of my '94. I am running HRE 547's in 17x8 and 18x10 on the street. I am looking for a cost effective track wheel that will have adequate backspacing to accomodate the '96-'97 Porsche Turbo rotor and caliper that the MoVit kit is based on. Does anyone have any experience with this combination? TIA!
