PFC claimed to be able to tell from photos of my wrecked rotors that the ABS system was overloading the front on my car. This is on the stock 360/350 rotor sizes.
A lot of people with square tire setups and modest power increase use a 372mm front rotor with stock rear. The Brembo and ST kits use the same size rear rotor (355) as PFC, but go bigger up front (380) than PFC and AP (372), which I think I will need. Fortunately, the ST kit fits.
I'll report back.

Do keep the thread informed. I didn't know the Z54 kit was discontinued, maybe to make way for the ZR94 tubeless caliper. Plan to call up there and get the scoop. GL w the STs.
