Get what you pay for at the end of the day! You race though and majority of members on here trackday at most. I must admit the paint on mine and my mates golf both caught a light arround the ring... And he had cooling ducts.
But for the most they are a cheap alternative and last alot longer than some of the other pads i 've seen out there.
I paid for the full race version (YellowStuff R?), and after bedding in they only lasted two testing sessions, maybe 16 laps at the most?
By the end of the last session they were fading badly, and so I decided to call it quits and by the time I went back into the pits they were well alight. Some quick thinking by my support crew put them out.
They weren't cheap, but not as expensive as Pagid (for good reason, Pagid are the very best you can buy, RS4-2 Blue is the best street/trackday pad you can buy, bar none), but I would have expected them to last a little longer than they did. After we left them in the pits for the rest of the day we had a closer look to find the pad material separating from the backing plate, and deep cracks across the pad surface. You could crumble the pad material away with your fingers!
Funny thing was I had been warned about them by another racer in my class, but thought "they can't be THAT bad!". Sure enough, they were ****.
The V8 guys here in New Zeland have to run EBC as a sponsor thing and they all hate them. They use a set per race
As a comparison one of the drivers used a defferent set of pads (can't remember what they were sorry) for the endurance series (three four to six hour races) and the pads he had lasted the whole series!
