Brake discs STOPTECH or OEM Volkswagen

I just (like Friday) got slotted StopTechs for the front. I got Hawk pads and can confirm they stop the Fiesta in a timely manner. Outside of the silly blow-off valve, the only modifications I have done have been StopTech rotors front and rear.

Personally I really like the StopTech Slotted rotors. The slots do nothing to help braking performance but they do help keep the face of the pads flat.

Stock rotors are cheap and effective anything bigger is just for show.

GTI Clubsport rotors drop 2.2lbs per side at the front

I've run them on three cars. You won't regret them. I'm actually running the 336mm rotors on my c30 right now with a custom caliper setup. Been like that for 2 years with no complaints, and in total I've been running stoptech rotors for 8 years.

FWIW, I recently replaced my front rotors and pads at 40k and I have about 8mm on the back. At this rate, I'll probably have to replace the backs around the same time I do the fronts again. My rotors look nothing like yours though. Mine are smooth and no grooves.

I had the impression that those discs wouldn’t warp as easy as one piece discs but it looks as I was wrong. VW tried to machine my warped discs with them mounted on the car at one point but they failed so badly that they did not even want to show me the result. After that they messured the runout on new discs on the bench and found them OK. After the discs were mounted on the hubs they were messured again and that one of them had warped. That was the way they found the bad hub. I was quite surprised when I was told that VW did not have any tolerances for the runout on the hubs or the discs. I took for granted that they had quite strict tolerances both on the hubs and the discs. I don’t know if the eight piston caliper and the setup with opposed pistons makes the whole system more sensitive to warpage or not but that has been suggested. And to get this a bit more connected to the thread subject I can add that I have not found any alternative to VW original 365 mm floating discs at all. I was quite surprised to find them cheaper than the one piece 334 mm discs to my Passat W8 though.

I'm actually running corrado g60 rotors right now that i redrilled to 5 bolt since my last set warped.

Since I installed the StopTech slotted brake rotors on my 2013 Golf R last winter, every time I've driven in the rain, after cruising long enough such that the brakes get "cold," as soon as I mash on the brake pedal, there is no stopping power whatsoever. Once the brakes "heat up" the response and stopping power are as what I'd expect. On a dry day, this does not happen at all - the brakes are firm and the stopping response is exactly what I'd expect.

The rear brakes will be an absolute nightmare. There is not a lot of room. As far as I am aware, MK6/MKV R/R32 brakes are the same, so... prepare yourself for a miserable time doing the rear rotors. The rear pads are fine. The rotors suck ass.
