Used Reds and Greens back in the day when they were the shizz.
Both were prone to early fade.
Random build quality.
Poor build = poor fit.
Sometimes noisy.
Honda bike guys don't think much of them either.
There was a guy on an overseas Golf GTI forum who was a re-seller but even he didn't recommend them.
At one time EBC were making contingency payments to users and free replacements.
Product info all over the show.
Some brochures say Red/Green Ok for track work, some say not.
New formulations since I used them ?
Who knows ?
I don't recall any mention of ceramic material on the Reds I tried.
But if Al sez they are excellent, that's good enough for me.
;D
(Assuming that's the Al I think it is...)
Expensive at ~$200 for Greens, ~$400 for Reds.
For track alternatives try Ferodo, Mintex, Endless, Pagid etc
Usual riders... YMMV yada yada yada
