It will depend on how much weight you have in the rear end and what your brake balance is like. I had HC800 front and rear at the last track day and found that although it pulled up really well, the rear tyres were sometimes locking under hard braking. I will be using QFM HPX street pads on the rear next time. I think the HC800 just bite too good for the rear end which in my case has hardly any weight. On the front tho, they are excellent.
Keep in mind I don't have ABS as well.
