E-series with big brake upgrades on the track.

Guys just tyring to figure out what brake package i'm going to buy.. either the racebrakes or the cebco kit. Does anyone on here ACTUALLY DRIVE THEIR CAR HARD ON THE TRACK with these kits or similar? If so, how do they go, issues with warping the rotors??? I know the saloon cars run the cebco kit but the racebrakes kit is alot cheaper (although it has 1 peice disc/hub unlike the cebco which is slip on disc and seperate hub).
Cheers.
