Haven't been on for ages, thanks very much for your replies. Now have 215/45/17 momo europe's on and the way it eats corners is phenomenal, rebuilt most of the engine last new year. Replaced all bearings, rods pistons the lot, 2" powerflow cat-back and a hollowed out cat container and recently recalibrated the throttle closed position switch. Performance has improved way more than anticipated but, Seems to bog down and lose a little performance when it's warmed up properly, Just hoping it passes mot next month for now. Lacking in confidence that it will do!
