I got the same feeling with my 07
MCS. I took the car for a wheel alignment - it actually had +ve rear camber! The front was also towed in about 1/4" which didn't help cornering any either. It feels much more sure footed now with the rear at -1.3 degrees and turns into corners great with the front at 0 toe.
Still torque-steers/tramlines like crazy when accelerating hard on uneven pavement though.
