Total weight of one OE caliper loaded with pads = 10.8 lbs" --RB
that another half a pound a corner plus upgraded pistons and much better heat management not to mention much stronger. no more dust boots to fry because the piston is machined correctly. 2 allen or hex bolts to remove and pad swap. they sent me pictures but i cant view on phone.
i will respond via email or phone shortly while waiting for doctor.
