Help identifying these

[elcono]

Hi

Are these standard gti calipers? Does the 54 denote the piston size?

Also are these standard gti carriers? I haven't found any dimensions for the TT carriers to compare.....

From memory the gti (288mm) had 54mm pistons and the 312mm had 57mm.
not sure if that relates to the number stamped on it or not.

If i have my wheels off today ill try and grab some part number for you

312mm left, 288mm right

Here is a closer image. The only diff on the image I can see is that the 312mm carriers have a slightly more curved back near the larger bolt holes (on the left hand side)

I'm pretty sure these are 288's then.....
