dont bother with ebc they're crap.
i've spoken to loads of people with ebc stuff including ultimax, all warped, all shockingly crap.
also, one of my uni lecturers (teaches the motorsport stuff) tested ebc against ferrodo when he worked in a touring car team and the standard road compound ferrodos out performed the "better" ebc stuff by miles! ebc had no modulation and then the coefficient of friction shot up and they locked up WAY too quickly and suffered from heat massively. ferrodo had loads of modulation, high resistance to heat and better braking power before they locked up.
ferrodo all the way! why do you thing the ferrodo 2500 is soo much more expensive than ebc
