If the shocks are to long when you accelerate the srings lift of the spring perches and this causes an uncontrolable lift, which may vary from side to side of the car.
Also the same can happen in cornering as the car does not settle consistently as there is no pre-load on the shocks.
I am not saying you need alot of pre-load on the shocks, you just have to eliminate all the uncontrolable aspects of the suspesion travel. ie: springs floating around from to much drop.
I really think you need to rethink this. A Mini is so nose heavy that it would never lift the nose that much. Also, when you get the rearward weight transfer, you will get wheel spin. You would never get enough wt transfer to lift the springs off their perches.
Rebound in shocks can be desireable, but not for the reason you state. You build in rebound to get a quicker reacting shock on the rebound stroke of the shock. This can be used with certain set ups. Pulling to one side or the other when accelerating out of a corner could be helped with a little rebound in the shocks.
This pulling from one side or the other with an M05 has little or nothing to do with the nose lifting on acceleration. Has more to do with the diff and set up than anything else.
On a side note, I've been running a stock M05 ball diff for 6 months now and have had no reliability problems. However, I did use a little common sense and did not crank it down tight as a TA03 ball diff. Works really well and don't see much if any "diffing out".
