Anyone tried any of the above? I want some new front discs for my trackday RS2000 that runs 2wd Cosworth brakes but only want to pay £80ish as theses just no need for AP/Alcon etc. Found both the above but can't really find any reviews so wondered if any of you guys had tried them! Il be running them with DS3000 or XP8 pads

 

I've run the National Sports grooved discs on my XR4x4 for years, now on my second set after wearing them out. Can't fault them. I ran them originally with DS2000 pads, now with DS2500s.

 

Cheers mate didn't think they can be to bad if Burton power sell em
