ive just change my disc at the weekend to Dimpled Grooved and the pads am using are mintex pads and they have not squeak but its only been 5 days so we will see this is on a m-jet
I put some Brembo ones on my GP and I haven't heard a peep out of them.
I got them nearly half price though so that why I bought them they should be about £90.00 normally been on the car for about 5 months and they are brilliant IMHO.
