Second time I ran the M Coupe down the 1/4. I would like to see a 13.4 eventually. The car is 100% stock with everything in it.
Any suggestions?

315 hp right?

what was the weather like? track conditions?

that can get better with practice....better 60' can prolly be had.

Dustan, as stated in Z3, with a 2.0 60' time, you'd see 13.5 or so. But the trap speeds tell me the air density wasn't great at your track location. Do you know the elevation, temps, and humidity?
