I had an 2013 R8 V10 manual and that tried to bite me in the dry on a straight road (back end just popped out at about 30mph) R8 can be a little tricky due to the mechanical old school plate diff in the rear (as can it's sister car from Lamborghini) they also will not tolerate ANY variation in rear tyre size circumference and need a pair of rear tyres if one is punctured (within reason) anything over about 10mm difference between the two rear tyres circumference (dress makers tape or some of that plastic binding used around parcels is good for measuring this)
I test drove one at Chingford Audi some years back, it was downright dangerous, it's not really noticeable as the diff locks up with increasing power as you sub consciously steer into the pull from the rear, but, the moment you lift off and the diff releases the car will change lanes quicker than you could make it, scary if your steering around a corner at the same time, luckily this one jumped to the right, if it had jumped to the left we would have been in the Armco, the salesman sh*t himself
