The front brakes are upgraded from the terrible Sunny Gti spec tiny discs to a big disc kit with uprated pads. Very good on the road and fine on track with no fade even when pushing hard.
I was on track on my dealer day, chasing a Seat Supercopa that turned out to be one of the front runners in the MSV trackday trophy. It was a quick car, but i had a little to spare on the straights plus could outbrake on the bends, but they just got too hot as the fronts were doing most of the work.
This happened

On removal, it was even more serious. I had cracked both sides and both layers of the discs.



Must have been some serious heat in there.
No one can say i don't try lol.
New discs and better pads going on all round.
