I've been looking at pad and rotor upgrades at the moment.
EBC Yellows seem to have a higher heat range than the red's, but I haven't come across anyone who's used them here yet. Also looking at Endless, Project Mu and Ferodo 2500, but a mate of mine with 2500's on his 350, hasn't been impressed with cold bite.
If he is having a problem with cold bite the pads have not been bedded in correctly.
