90STX,
Nice to hear from someone that has before and after experience. I certainly wasn't concerned that it would be a problem,but it did get me wondering about it.
Plus, we have a feature that keeps the wheels from locking up when engine braking, so even if it did have an effect it would be further reduced any.
And it doesn't just spin from weight transfer, if you leave from a standstill with the wheels turned one way, it will spin the inside too.

no forgiveness required k! you guys know way more than me here and i'm thankful for any advice. gloomy, shoomy-things could be way worse: somebody could be shooting at me or planting ieds along the road i drive. a little lift throttle oversteer is trivial in comparison.anyway, i had the car up on stands over the weekend. all the control arms seem very secure against arm strength pushing and pulling. the h sport bushings appear in good shape, at least from the outside, and don't squirm around under arm strength force.
i rotated out the tires. they all show very even wear across the faces and no obvious signs of misalignment distress.
i'll try a liitle more negative rear camber and see what happens.

002,
Good thoughts, but it doesn't exactly work that way for a couple of reasons.
The inside tire spins on an open differential car because it has the least traction due to the weight transfer to the outside while cornering hard. Our engines don't produce enough compression braking to be much of a factor on dry, or even wet pavement. The reason the car oversteers when the throttle is closed mid-corner is due to weight transfer to the front of the car and the subsequent reduction in grip at the rear tires. The wheel chair analogy works for wheel chairs, tanks, and specialty cars with individual brake applications to the wheels. It doesn't apply to our MINIs or any other production car, nor nearly all race cars.
When I installed the Quaiffe in my MCS, there was no reduction (or increase) in trailing throttle oversteer.

from fifth gear R56 review...
this sounds just like my R53 !!! maybe it's from all that gold i've got on board."....Try to carry too much speed through a corner and the front end will tend to run out of grip first, pushing wide - but coming neatly back into line if you ease the throttle. And with the stability control system turned off, lifting off the accelerator mid-corner can produce some easily corrected tail-slides. Very Italian job...."
