R32 Gtr Vs. Gtst Master Cylender

[Birth]

Hi all,

I need a new master cylender on my R32 GTS4 (same cylender as a GTSt I think). I think that I have read that the GTR master cylenders are vacuum assisted which in my mind would make the clutch pedal lighter.

Are they vacuum assisted?

Will it work on a GTSt / 4 rather than a GTR?

Thanks.

Never felt the need to get vacuum assist on my GTS4, even with a HD pressure plate.

I agree - the pedal is not terribly heavy - but I am replacing my master cylender because it is leaking and thought that I might go for an 'upgrade' if it works.
