I am unsure of which one come stock on the OB's, but it would really all depend on what you plan on doing with the car. If it's just a driver and never going to hit a track, then leave them alone like Mike says. They stop pretty good with a little extra foot pressure. If they will be tracked (DE, AX, etc), your gonna wanna put bigger brakes on their. They "will" fade as the little steel calipers don't dissipate heat very well. I'm upgrading my brakes to S4 Calipers as I plan to Autocross my car. Although I probably didn't answer your sliding/floating question
