Agreed, all these numbers represent traction limitations. With drag the car will be much faster, esp once the faster autos come. Power and torque is NOT the limitations here.12.70 for mine stock .. Traction is a big problem for my M6 with stock tires ..Auto trans in stock forum should do a little better ..
That is really good, anything under 13 stock is very good but getting near 12.5 is beast.12.504 for me. Automatic with 3.15 gears
