I haven't had our SRT8 300 to the track yet. But the "50%" traction seems to be the best. According to the performance timer in our car it did 0-60 in 4.88 seconds and that is just like it came off the showroom floor.

I found the key is to get the tires to spin just enough so when it does hook up it doesn't pull down the engine to much.

I know this 300 is the funnest car I have ever owned. I love my cuda, but for everyday driving you can't beat the SRT8 cars.
