are the stoptech 332mm 15lbs rear rotors 1 or 2 piece? and i'm assuming this are ok for straight swap to fit with stock rear caliper?

thanks

also, just wanna tell you that you're doing great job with all this loosing weight thing. the car.

 

Great info Eric

 

@teeithi: they are the 2 piece rotor option in stoptech's BBK. NOT the 1 piece powerslot rotors. Those weigh in around the stock 23 lbs

 

thanks buddy i looked forever for something like this when I was trying to decide on my AP racing bbk vs. stoptechs. One thing I like about AP racing is the lightweight and no rust ring. The stoptech BBK still get the same rust ring I had on my powerslot rotors from the pictures I saw

 

Yeah that I've heard and seen on stoptech rotors :/

 

Thanks for info !
