Sorry, haven't been on about this recently, been out the country and other commitments. I Know - There is no more important commitment than "Your Caterham". Simple answer first, John, yes I can pull away without throttle, idle speed shows as 950. I am in the process of comparing this Backlash with other LSD cars. It would be nice to find the official "workshop" figures though. Elie I will try Phil. It's not so much clutch control. You just have to disconnect the drive when the revs drop below between about 2000 & 1700 as you slow down. Rob, long live "popping & banging". Gordon
