Yes, for the Rotora 6 piston, it's the same pad as the Stoptech ST-60. That means it's the HB-109 shape. The maximum thickness that will fit is 0.75 inches (pad material + backing plate).

It doesn't take long to cause material transfer. Especially if you're running street pads. Even on my race pads (DTC-70 Hawk Compound), it only takes about 3 laps to get me the necessary pad transfer.

It's going to be really hard to get a combo pad. If you run the HPS, you will most likely exceed the pads' max operating temp very quickly. The HP+ is slightly better, but you'll probably have the same problem. Anything more aggressive and they won't work worth crap on the street and will chew up your rotors.

And honestly, with your drilled rotors, if you try to run race pads, your drilled rotors will probably crack within one weekend. Having gone down the cosmetic route, you're kinda stuck with running street pads and just driving really slow and easy on track. Sorry.
