997.2 front rotors warped

[mm450exc]

2010 GT3. Vibration started about 800 miles after track day. Front rotors 0.8mm off.

Alcons going on tomorrow and will have car fully checked before. Anybody had any problem with the hub assembly(runout) or something else that messed with the rotors?

I think that I replied elsewhere. My fronts warped slightly on the 997.2 (nothing like as bad as the rears). JZM couldn't find a reason why and Alcon were out of ideas too so I had them skimmed. Okay so far, but unknown whether it will happen again. I'll be running with the traction and stability off at Silverstone (unless it chucks it down) so it will hopefully be just like going back to my old 996.2.

Those standard GT3 brakes are proper junk! Even the rears were about 0.6mm off and I always have SC/TC off. The front were way warped at 0.8mm off. Alcons feel a lot better plus the larger rear. Let's see....
