I have a question regarding the 4 PISTON 13'' (332mm) STOPTECHs.

Are the caliper sizes the same/similar between the ST-40 4 piston and the ST-60 6 piston stoptechs? I know there are other sizes out there like the Stoptechs that come w/ the 13.5, 14'' rotors. The pads are definitely larger on the ST-60s (checking the website).

Just want to understand the aesthetic differences between each... I've sent a few PMs out to the owners whom pics I saw, but would like more feedback

Thanks
