I can tell you all that we can take it 1 step further and step up to the 6 piston front and 4 piston rear as on my SSB srt 6 .....but even better the 8 piston front and 4 piston rear as I have on my 04 NA Frankenstein coupe . (see picture) the donor car was a SLK65 p030 performance package car,
front rotors are 360mm and rear are 330mm. these are bolt on and can run aftermarket rims with 18 front and 19 rear. Mandrus work for the correct clearance as well as the rims in the picture.
