Good advice, to change the car, not you. Find the place on the tree, where you are golden, then change the car to suit. Try the other way around, and you'll soon have a legion of vultures following you to staging. You might find a delay class WAY cheaper in the long run, HOWEVER, the competition will probably much tougher, too. Good luck.

Well lets throw the leaving on the green out the window first. That will always bee too slow no matter what. If you have 60 fts in the mid 1.40's you should be able to leave at the flash of the 3rd amber and not go red leaving at a dead idle. That's another thing.....I have never been able to get a car to react consistently leaving at an idle foot braking. You need some RPM to tighten the drive line and suspension up before you leave. Try 2000 RPM and see how it works. If you RT is slow go up in RPM and vice versa if its too quick. What you have to be careful of is not to anticipate the 3rd coming on. You need to leave when it comes on.

You're probably right. When initially working with the car I was all about best ET, now I have to forget that and work on best reaction times so I can go some rounds. The car definitely ETs best off idle, but it makes sense that it would be more consistent to leave with the suspension loaded.

All good advice on changing the car. Dont forget car placement in the beams is equally important for consistant reaction times and consistant ET. Make sure you barely turn on the second stage bulb to indenty you are on the same mark every time. This can be a differance of 2 hundreds on the starting line and the finish line. Stage deeper in the second bulb you will go 2 hundreds quicker on the tree and run 2 slower down track.

Not the case. Since leaving off the yellow was too slow, I would pause and try to hit it half way between yellow and green. Since there was nothing to consistently react to, I was all over the place.

I think you are mixed up here a little.
If you were slow leaving off the yellow, waiting to leave between the yellow and green would make you even slower.....
Yeah, I wrote that wrong. Leaving when I see the yellow leads to a red light, which is why I paused and hit it between yellow and green. Sorry for the confusion.

Ok, let's say I want to leave on the last yellow. Other than a delay box, how would I slow down the car's reaction?
I did read where one of you said staging RPMS, but leaving off idle should give the slowest reaction since the engine has to come up on power, the suspension has to load, etc... I may be mistaken, but I would think I am already setting the car on the slow end of reaction.
If you are going red leaving the line at a dead idle you are anticipating the 3rd light coming on.
Yep - almost for sure on that. This was something I had a problem with ( especially running slower cars ). You have to discipline yourself to make sure you see the light come on before you mash on it. As said, a practice tree will help, but the best thing is just time in the seat and sticking to a routine. My routine starts once I am positioned in the water box. If I have to shut down after that due to track conditions, I always back all the way out of the box and start over again - no matter what my apponent does. I also always look at his dial to make sure I know who is going to be leaving first.
