Not the same but for feedback from a Caterham friend.

He went to EBC Yellow and had similar problems. They re-seated the discs calipers and gave it a good greasing and most of it went. He also had the issue where it wore his discs out faster but he has a 30lb right foot. He does track the car and so they get hammered all the time.

I have the EBC Yellows on the heavy ML63 and they did not squeal at all and I have a 20lb right foot. They also wore the discs out a bit quicker I expect so I have just fitted new discs and EBC Yellow and they are also not squealing.

I suspect Yellow's are just too hard for something as light as an Elise unless you are repeatedly hammering them.

I used to have Mintex in tuned road cars and never had a bad experience.

Everyone loves a Morgan. Even me, unless it's broken again.
