[QUOTE=ronin951;14885536Also the calipers are very light. I was shocked when I picked one up. No numbers, sorry. I haven't personally seen 335 M-sport brakes, but the M-performance calipers seem very rounded and hollow. As if they hold more fluid.[/QUOTE]

Online Datasheet says they are both 8lbs per caliper.
Original caliper (with 340x30mm rotor) and M Performance Brake caliper (with 370x30mm rotor)
Front Brake pads for M Perfomance Brakes are a bit less. But Peanuts.
