didn't have 256' date=' had 239 as it's an 8v, and the difference is absolutley unbelievable,there is no comparison, you can stop very quickly and safely at any speed, loads better than than the vr's probably due to the extra weight in the vr, the worrying thing is if something behind you hasn't got the same stopping ability, if you do it change the master cylinder as when i first did it the pedal was nearly on the floor so put a 22mm on and all was well,[/quote'] cheers for the advice rob
