Well I watched a Top gear that had a mini (the BBR one) with 280-something bhp - I don't think that has a LSD not sure though, and I must say it looked an absolute monster - I want one!!!
At Donny the other week (wet one) the MKIV was much nicer to drive with Racelogic firmly OFF.. This is my preference to applying power rather than let some electronics try and clamp wheel spin. Makes for better progress. Too many gizmos and driver 'aides' these days. People forget how to actually drive. MKIV is very drivable as is the Ibiza... 1st gear is not tractable but the rest pretty much hook up OK in the dry. bill
