Does any one have information about Brembo GT kit's calipers' piston sizes?
F: 380x32 mm discs / 6-piston calipers
R: 380x28 mm discs / 4-piston calipers

It's quite odd that the PDF file above doesn't include any info about piston sizes while for racing parts there's even drawings...

for 1M1.9016A/1M2.9016A and 2P1.9004A/2P2.9004A ?

Shows the M/N family as 36/30/28 and P as 38/38 although I think it is highly dependent on the last two numbers on the caliper model number. FWIW M was listed as 20.9732.XX-209735.XX 29.9736.XX and P as 20.A175.XX-20A176.XX 20.A177.XX

After reading through this cluster, it appears that there are multiple piston sizes per family. http://www.m3forum.net/m3forum/showthread.php?t=115391 I guess that means without the actual kit, or part number you are back to square 1.

Thanks! You're much better googler than I am... But I might be able to get the actual parts numbers, so stay tuned.

Brembo marketing literature and web info kinda sucks. The racing parts info are pretty good if you can find it, but they have lots of things available, like pads, that they don't show in any catalog. IN the US Brembo is distributed by race technologies. You best bet is to work with a local shop that sells brembo and get the details you want from them. I use their rotors, type 3, and they have been quite good about questions regarding the fit, application, pad choices, etc. The brembo guys they work with are really responsive.

Why would you want to know the piston sizes? Just email the kit numbers to sales@racetechnologies.com and they'll get you the information.
