This is part of my point though that for a track day stock is just not up to it i think the portafield pads melted then the metal on metal could have cause them to crack, or due to the thickness of the rear disks being as they are vented aswell probably did not help as i have had a couple of sets crack.
cant be bothered to go into the whole brembo v uk set up in my view the fronts proved there worth on that track day, wish I had the brembo rears sorted before I had done it now as im sure they would have held up.
The new supra is running a full uk brake set up, wont be far off the same power as my old supra, when it gets put through its paces in a couple of months ill post up if im wrong or not about the evo brembo conversion;)
