Yes my setup is 40lbs +/- lighter than stock...as long as my math is correct it's actually more than, but I'm just playing it safe.
Yeah the 360 size will be enough for me and I upgraded to their "lightest duty" track pad on the front, with their highest performance street pad in back.
They DO make an over sized kit for you none believers (if you want something bigger than stock size).
They are doing their R&D on a 6-pot caliper setup for the front. They are also redesigning a new caliper bracket to move the 4-pot that I have to the rear rotors.
So this way you can have your cake and eat it too!
