Brake specs?

Does anyone know the specs of BA 1.8 astina brakes?

as i'm looking to upgrade and i can get a set of these for a respectable price...

but i need to know caliper widths/disc widths/clearances etc...

these will be used in conjunction with a set of 325mm discs (probably from DBA)

Dan,
I dont think they will fit. If you take a ruler from the edge of
the rotor to the inside of the mag I dont believe it will be 50mm
as needed by the 4 piston. What makes it worse is that that is based
off a 28mm thick rotor, change that to a 40mm thick rotor and that
makes the clearence required even more. I tried fitting some mitsubishi
GTO rotors and 4pistons callipers and couldn't get my wheel to clear the
calliper.

Best of luck

yeah i measured my clearance today too. i had 70mm from disc to spoke running parralel to the outer edge of my stock disc. the clearance however would go to the **** after that as my spokes curve in heaps as they get nearer to the tyre

cheers mike
