UPDATE QUESTION:
Just wondering since I just checked on prices and the Brembo and ATE (elliptical groove) front rotors are within a couple of dollars of each other. Thoughts on either of these before I pull the trigger, or is it six or one-half dozen of the other
Thanks!

SC Rotors are only 20mm wide. They are a normal replacement item on tracked SC. Track miles vary; but the last set lasted 1600 miles.
Caliper rebuilds have about a three event life. Ironically, only the outboard half of the caliper begins leaking. Clean the bore throroughly and polish the piston with scotch brite or imperial 2000 grit paper. It seems the shinier you get the surface the longer the seal survives. Probably don't need to put the dust boot on because that doesn't make it through a day. Two people driving. If you only rebuild one side, you can match the piston orientation to the oposite side.

If you know a good machinist, get the oem and have them 6-slot (not drill) the rotors. Slotting is superior to drilling because it leaves the rotor much stronger. You will have an OEM strength rotor with good gas brushing abilities. Never drill/slot. A big gimmick that leaves you with a very weak rotor.
