Well had my car to track a few wks ago--

Its a m6 car spec 2+ moser 12bolt 4:11 gear--Viking DA Fr Coilovers/DA Rears(set to their rec spec for drag) 300# springs-- 3pt sfc's tubular a-arms up fr and tub k-member---no sway bar up front--adj torque arm-rlca's and salad shooters w 26x11.5x16--car has 355/370whp/t

I ran car 5 times on a pretty much perfect night high 60's no humidity--i cut consistant 1.7 60' and consistant 12.4x @111.. i left at 5000 w 12psi in rears---car was way low as you can see in video --i have since raised it up and installed a tach--i think i was shifting way low--just curious as to what most guys w r leaving at w m6 cars that are cutting 15-16 60's.. any input would be great thank!! i feel the car should run better than a 12.4
