There haven't been too many pics of these floating around yet. Just finished the install yesterday. Actually, I spent most of the day bleeding all four brakes. ST-22 rear 2-piston caliper with 328x28mm rear rotor. Up front I put the ST-40 4-piston caliper with the 332x32mm rotor.

The wheels in the pic are 18" Nismo. Weight of the entire Stoptech system is 107lbs vs exactly 100lbs for the stock system. This includes all lines and pads. Most of the weight gain is due to the larger rear rotor. Weight gain in front was only 0.5lb per side. Very impressive.

 

looks great.. mine is getting put on next week!!
