I've been wondering what tyres to fit to the M2 when my OE MPSS are worn out. I think a track biased tyre may be the way to go as I do the occasional trackday in the car so need something with a stiff sidewall that won't get all gooey when its hot!

Federal 595 RS-Pro and AD08RS are currently top of the list.
To add to my previous comment I will probably increase the front size to 255/35/19 and retain the stock rear size at 265/35/19 whatever tyres I choose. Hopefully this will tip the balance of the car forwards a little more; especially when combined with my 2.5deg of front camber.

I know the car has plenty of torque to neutralise the chassis but I do feel that the stock setup encourages the car to push and understeer a little on turn-in in almost all weathers. I experienced the same thing on track in the dry, the rears just have too much grip when trying to get the car to rotate with the throttle closed on turn-in!
You can fix this issue with adjustments to the tire pressure. Here are some thoughts for you: first, try the same tire pressure front and rear for street use rather than the recommended staggered tire pressure which runs more tire pressure in the rear. For track use I have a staggered set of 245/40 front and 265/40 on the rear on 18" wheels. For track use I run 2 pounds higher tire pressure in the front tires vs. the rear. I don't have camber plates and my track tires wear pretty evenly. I also have a staggered (245/40 front and 264/40 rear) winter setup on 18"wheels.
