Are there any out there that have practice trees that I can use to help with reaction times?

Thanks Steve I've been on ther for about an hour now.

I just can't seem to get it better then an average of .550 light. I can't believe how quick you need to leave when you see the 3rd yellow. At the track I was waiting to it was almost a green light.

Average rollout is .300, but cars vary. A quick car off a transbrake with small front tires will have a much quicker rollout than a 19 second pickup truck.

As far as how to calculate it, find your average human reaction time, then subtract that from your average lights. If you average .550 lights and your human reaction time is .200 then your rollout is .350.

If you can, buy the old IHRA game. Pleanty of pratice plus it has a dyno program to set up your engine and you can tune for suspention.

I got my game for 20 bucks.

Is that a play station game or a game for computers?
