HI all

can anyone advise me please
i am doing a trackday at oulton park next saturday in my focus ST170
and want some uprated front pads but dont know what to go for
greenstuff or red stuff
is redstuff too hard for a 170bhp focus cause it says 200bhp+ on the ebc site
i not bothered about road performance as i going to put std pads back in after track day
what do people think green or red ??????????????????????
