orginal disk with orginal pad is perfect, won't kill the disk, but a pair of new front pads only last about 3 trackdays.
orginal disk with DS2500, a lot more stopping power, perfect for road use, bit nosie and dusty, because they are harder pad, sometime may warp the disks at track, depend how u driver, me and Mark did.
best solution is get a set of racing version Brembo brake set, cost depend on what size, racing team can get them a bit cheaper, can even get small version of 4 pot to fit 15 wheels with slicks, u paid what u get for
i was nearly go for that......
then i get my self Endless S6 brake disks, DS2500 for road use, highest temp racing pad for trackday, no more warp disk. can even lock up the wheel with semi slick tyres on, hotter temp will give u more stopping power, is totally differnet level of stopping power.
i do highly recommand change to some top brand brake disk if u go trackday often, is save time and money for long term becuase they will last u a lot longer, so far i have no problem with the orginal DC5 brembo capiler they are working really well.
never use slicks before. so not sure how well will they perform with slicks.
