Quite interesting discussion....
I'm running 28 PSI front, 32 Rear on my WRX.
Mind you, that's also an AWD car, and most of the force (under breaks or acceleration) around a corner is on the front outer tyre - so the lower pressure creates a hell of a lot more grip (and wear on the inside of the front tyres!)
I had a blowout on the M2 @ 110km/h back in March. The front left went. It was a struggle to get the car under control and eventually used the handbrake at 50km/h to get the tail back aligned in the breakdown bay.
It turned out that tyre rotations on AWD Subaru's is so hard to guage, you end up with bad, bad tyres. I had 40% tread on the outside of the tyres, and it was through to the metal core on the inside of BOTH tyres. The rears were perfect. There was a lovely strip running around the very inside of the flat of both front tyres where the metal core was sticking out.
Very lucky
