PBS and Mtec here, changed for a track upgrade and never looked back to be honest. In the near 9 years of ownership these are the best I‘ve experienced. They are very dusty, but I‘ve had zero issues with fade, shuddering etc (disks are hooked) and even driving normally from cold the bite is perfect. Not once have I braked and found them to be in-sufficient under any circumstance. The hotter they got the stronger they got, unreal performance from a simple pad upgrade.
Only down side to them is dust, White wheels turn black very quick haha. I‘d even say the ds2500 pads were more noisy when I had them years ago. Sounded like a bus with those in. I‘m yet to experience any squealing with these that‘s embarrassing/ off putting.
Adam (Gok) used to run Mugen in his. Believe he was happy with them.
