The gothamracing.com brembo (rear) rotors are about $40 extra, they claim to be zinc coated while rx7store.net does not (which doesn't mean they aren't zinc coated). Anybody else know what accounts for the difference in price? I ordered from gotham but could probably cancel the order if there is no difference. Thanks.

 

I dont know, but i would get the cheapest rotors i can get.
