What methods can I use to slow my reaction time (RT) down. I think I am cutting a good light but, I am consistantly red-lighting by -0.02. When I try to slow myself down, I am so late (.14 RT) I am beat before I leave.
I have tried letting air out of the front tires which helped a bit but not enough. Will reducing my launch RPM help? Any advise?

Lower launch rpm will help a little bit. Michael Beard can provide more precise #'s, but going up one front tire size may get you close while 2 sizes should take care of the .02-.03. Then you can continue to fine-tune with air pressure. Couldn't hurt to try stiffer return springs on the carb, looser shocks and some people vary rear tire pressure a bit. Less air = more wrinkle= slowerer vehicle reaction. But I prefer to keep rear tire pressure where it provides the best contact patch.

Oh been there, done that: Assuming you stage the same way each and every time(shallow) and that you stage straight. I block the tree now with the visor, seems to help most of the time....for the driver part Other things that work but not always it depends upon how your car is leaving: Car related: Try one at a time if they seem rational at all: Lower launch rpm by just a tad rear tire pressure reduce a bit, are we using radials, or bias plias cars reaction time is affected. Add some weight to the car Add some suspension travel for the car Bigger front tire take some timing out might try a different launch engine temp.....car reacts differently at 120 degrees versus 150. Aircleaner.....with a rocket ship like the gremlin....its good for.02-3 by itself.....2-.3 in the entire run though. Driver: close one eye polarized sunglass attachment Move seat back Brake pressure gauge...have one and and figure out what pressure you leave at and go red.....then add a couple of hundred pounds..... You can still go red blocking the tree....especially if you creep. Eric

All, thanks for the replies. Will try the easy and free things first. Thanks again for the advise.

Closing one eye helped me, but make sure you close your dominate eye. I also pick a spot on the light bezel not the light itself. I also have a toe hook on my throttle pedal that I lift my foot up against. I can adjust how far away my foot is by changing how far away the hook is.
