If you get the launch right it's quite effective
I'm just having clutch slip above about 4000rpm and in higher gears.
I think the cold makes the clutch material less "adhesive" there is more bhp from the cold air and I'm v gentle on the clutch (hardly any slip on hill starts etc) and my journeys are short so I get no heat into it.
Add to that 210bhp into a clutch made for a 150bhp colt t doesn't take a rocket scientist to work out why there is a bit of slip.
Anyone else experiencing similar??
Oh - and as for the BRABUS, I think I was told that the car has 2 distinct maps.... 1 for first and 2nd and another for the other gears.
