Just got referred here from the M3 forums by 'surly'... thanks!
2010 E92 M3
Michelin PS2, 245/19 front, 265/19 (?) rear
Settings: DSC off (no nannies), "power" throttle, "normal" EDC, all else standard.
Conditions were excellent: ~60 degrees, tail wind on front straight
Best time 1:58.9
Top speed front straight: 141 GPS, ~145 speedo
Car pushed like a pig so I had to drive around that. After reading a bit, it appears that this is standard for the E92 with a stock set up.
I have a lot of laps at TWS in an SRF so it took a bit of getting used to in a heavier, mediocre-handling car. I expected the tires to have more grip than they did. I coaxed some oversteer out of her to try and optimize exit speed but it wasn't a cake walk to do so. These were my last couple of laps out of maybe 12-13 hot laps total.
Even with the nasty understeer, it's a really fun car to drive. I can't imagine it on decent tires and a square set up.
