vRS Carl:

Carl I have been running my KO4 for 10k now and on 312's. They are ok for road use. There is not much point changing them unless you go on track or the ring..
vRS Carl:
Thanks Mickey.
I have been thinking about it more recently and just feel that the DS2500's & 312mm Discs will be fine for Road use as i don't drive like i Stole it.
Carl :happy2:

I'm also using the R32 front brakes for quite some time and tracked them at Nurburgring last year. The pedal feel is much better that the OEM 312s but probably the cold stopping distances are about the same. The problem is when you start heating them. I have a very nice mountain road of about 40kms (somehow similar to Stelvio pass). I've been there with my OEM brakes and they never lasted more than 10kms under very hard driving. Black smoke came out, pedal became stiff...With the uprated R32 brakes + DS2500 pads, I finished the 40kms and 3 consecutive laps on Nurburgring with 0 fade. Knowing I do have quite a lot of power/torque as compared to stock, I would go even higher with the brakes but I'm afraid a small improvement over the R32 brakes would triple the costs for the brakes. Anyone tested the RS4 fronts against the R32 on mk5 GTI ? I would be curious about the differences in fade, stopping power and handling (don't know how heavy RS4 ones are compared to R32 ones). Soemthing interesting for me though was to find out that the discs from VwRacing brakes were about 2 times lighter than my R32 ones wich should mean something for handling. When my friend TEFF (present here on the forums) will install them, I'll have a run in his car and report back with the differences !

The RS4 discs are a fair bit lighter than the R32 ones even though they are a bigger. I held them side by side and there was a clear difference in weight. The RS4 discs have alu bells. :happy2:
I havn't tested them enough for fade yet due to our bleak winter but the actual stopping power is night and day better than the standard GTI brakes. :love:
