Ello Sorry I never had the chance to stop and chat etc at the show! Looks like those 20 minutes have changed your life/car (same thing )! I would suggest buying grooved discs or having yours grooved, it makes an enormous difference in my experience. I swapped from XR2i calipers and grooved 249mm discs to Wilwood 4 pots and 285mm smooth discs, and the jump in performance should've been much much bigger. The discs are extremely glazed, as are the pads, and I'm sure it's down to the smooth surface rather than the grooved face that helps keep things that bit rougher. Rally Design refused to groove them for me at the time of buying, but I'm looking to get someone to do them for me before too long, I know they'll sharpen up.
