Hi sam, every car on stock brakes (in good condition) will pull up with less pedal pressure & do it more times in a row before the fluid boils and the pedal goes to the floor than a car fitted with ebc discs+ greenstuff. (say 90mph down to 30mph) By the way Im curruntly running ebc ceramic on the front of our 341mm disc/Porsche turbo front brake kit ,and works well. The guys at ebc are nice and the right pad on the right application from ebc can be excellent.However If something performs less well than stock (in good condition) then whats the point,? There are New GTT discs & pads packages coming very very soon. The two 'benchmark products' we are testing back to back against , are Stock & the EBC grooved/dimpled discs + green stuff. The comments made are from extensive hard testing, though I must admit we havnt included a dust test
Best Regards Roland GTT
