skuncan67:
Dear All,
I was interested to know if anyone has done this upgrade to the rear...using the fitting kit in the link below..

Does the OEM master cylinder cope with this setup and 6 pot Z18 on the front ? my gut feeling is not !!
any thoughts or feedback would be good...
thanks
Duncan

I'd argue 18z and stock rears are going to be a bit beyond the stock mc. You can upgrade to the RS3/TTRS mc but I think you need to change the servo. And seek expert advice regarding that; from what I've learned it's quite possible to get it very wrong.

Thanks, but just to clarify my car is a R32...so i dont know the different between the MC of mine and the RS3... ??

@Shoduchi can hopefully tell you more.

Your mc is the same as a GTI mc. A few early GTIs got a slightly smaller mc.
From everything I've seen, 18z on a GTI is just about possible, but at the edge of the limits of the mc.
