If comparing the BBKs in the same size made for other cars is acceptable, we can do a quick comparo.

Using the stock weights from this thread and/or the racingbrakes forum/store. The weights of the stoptech trophy kit from a google search.

OEM rotor : 21lbs
stoptech rotor : 17.8lbs
racingbrake rotor : 18lbs

OEM caliper : 13lbs
stoptech trophy caliper : 6.8lbs
stoptech ST-40 caliper : 7.8lbs
racingbrake RB460 caliper + bracket : 9.9lbs
racingbrake RB460 caliper : 6.1lbs

Did not compare brembo kits as they seem to be more expensive. And don't think that AP has a 4pot bbk for the front....just for the rear.
OEM front rotor is 22.5 lbs. happen to have a set sitting in the garage so put one on the pelouze.
