Doing research on the rear brakes for the ST I came across the Frakenbrake upgrade. I noticed it uses a 302mm Volvo rotor. I also like the RS brake package for the ST from Ford Performance, however all you are getting is a Nitrous Blue caliper and RS pads for a pretty expensive price. I have pieced together a list of the parts and prices for the Frakenbrake upgrade using RS Rotors, RS Pads, Mazda Brackets and reusing your OEM ST caliper. Has anyone completed the upgrade using the RS rear rotors?
