ATF versus G60 versus Brembo piston sizes.

[Schaible, David]

I thought the girling capilers were named for the cylinder size, where
the g60s were 60mm (upgraded from the g54s,54mm which came on the early
urq 
etc.)

I was able to locate Boxter S Brembo caliper spec: a pair of 40mm and a
pair of 36mm pistons.

I have measured and compared the CSAs of both systems. They are  
identical.

You can have either of the two backing plate styles refilled with the  
material of your chioce. So, what's yout bitch?
