I have the stock setup and did my M Coupes first AX this weekend.
running 245 front 265 rear Dunlops star specs
stock alignment ( did not have time to max the camber etc..)
Ive notice the rear really wants to come out while on throttle.
coming down an off camber turn just killed this car and it pushed like a pig.
Initial turn it seemed pretty good though. Then a little throttle steer while in the sweepers.
I was fairly pleased with the slalom transitioning
stock brakes were also not bad.
These cars have some great power just need to keep the rear from coming around on me.
Car did feel a bit like a sailboat on pillows compared to my Exige S though.
Might think about some stiffer single adj. Konis with the stock springs ( cant change the spring rate)
Any more info or help with alignment would be great.
Make sure the Konis will be softer than stock the problem with the M suspension is that the struts are too stiff for its springs.

I haven't messed around with the suspension for autox but i felt that car understeer too much and that stock the toes is push in too much and needs to be closer to center. This may not be for you because i actually like the car to rotate easily through throttle input to get around the tight corners.
