im doing an engine rebuild on my na s5 rx7 right now, i need a new rear rotor and rotor housing. well i found a rotor on ebay for 150 that has 40k miles on it and the buyer says is in mint condition. assuming it is, the weight on that rotor is d, both of mine are c, would i be able to use this rotor in conjunction with my good front rotor? thanks.
