Brake pads EBC or Carbotech

I’ve used carbotech XP10 for years because it’s the only pad that has never had any of these kinds of problems. Also also swapped between 1521 and XP10 seamlessly. The only time I had a problem like this was when I used some very cheap rotors that couldn’t handle the track abuse, you could actually see the rotor surface getting pitted. Yours look fine by comparison.

For my GR86 Carbotech XP10s have been amazing on the track, seriously no complaints at all. The XP10s with Castrol SRF have been a great combo and held up really well even on some really big/high speed tracks. I swap in my OEM pads when I’m not tracking the car for awhile. It’s not great because I have to bed the pads every time I change them. Once I’m through the OEM pads I’m going to get the Carbotech 1521’s for the street, that way like you mentioned I think I can avoid having to avoid bedding my brakes with every change. The XP10’s function well on the street but they feel a little rough if not up to temp and they are insanely loud.

EBC says that their racing RP RP1 brake pads are compatible with their street lineup. So swapping pads back and forth won’t be a problem.

I personally use Carbotech XP10 for track and Stoptech Sport pads for street on the same rotors

EBC Redstuff pads

I use EBC YellowStuff. They are great on the street and very predictable & consistent at the track. My local track is not very brake intensive: I’ve run 8 track days on the same set of pads plus lots of street miles in between. They’re due to be changed before my next track day.

EBC Bluestuff NDX Appears to perform similar to DTC-30/ME20 or equivalent as a hybrid street/track pad. I know a couple fast drivers that use them with no fade. They're cheap enough that you might as well give them a shot, make sure "NDX" is in the product id.

EBC pads are highly overrated for the price. Red stuff are pretty squealy and dust more than stock. Initial bite is about the same.

I used to destroy ebc pads in my 2002 WRX at leguna Seca.

I’ve used EBC on my previous TTs, lasted 3/4 of day at Limerock
