If you are going to the track use a BP40 or Willwood A or B compound. The A will make your eyeballs pop out, but its not a street pad by any measure. The BP40 is also not a street pad. I'm running the BP20 and its awesome on the street. Infact it dusts less than the OE rear pads. I would stick with the OE rear pad as its good throughout its temp range. Plus it behaves nicely on the street. Besides, FWD doesn't use the rear brakes much in normal use. It will however get hot enough on track to turn the rotors blue.
