That's pretty high, but not crazy. Lowering the pressure will slow your reactions, but there isn't a ton there if you are keeping the pressure within reason.

I run 32-35 psi in my 3600# Super Street car. I typically bracket race it, and use starting line RPM to adjust reaction rather than tire pressure.

I can't tell if your question is:

1. I run 40 psi in my tires and I think it might be too high, but what will happen to my reaction times if I lower the pressure?

2. I need to slow my reaction times. Will lowering the pressure in my front tires accomplish this?

If #1, I'd probably drop 5 psi and you likely won't notice the difference. If #2, I'd still drop 5 psi, but you'll get more change in R/T through RPM adjustment or rear tire pressure.

More in lowering rear tire pressure so they wrinkle more.

I am trying to slow my reaction time down. When I am green it is is about a 015-020 But I go red alot by about .012-.015. Don’t win many races when you go red. Just trying to slow down reaction time without changing my spot on the tree. I might need to lower both front and rear tire pressure. I know I could lower my starting line rpm some as well. Just try to see what you guys think the best way to do it is.

Put a taller front tire on, if you have the room.

Not sure what size front tire you run but I run a 28" with 25 to 30 psi depending on roll out but as Lee stated don't overlook the rears. There's alot you can do there especially if you run bias ply tires.

I’ve generally just lowered the RPM to slow RT, doesn’t seem to affect ET as much plus you can adjust that or not “on the fly” if you see everyone spinning like crazy or you’ve just packed in 50 pounds of lead. You can add some shock extension too and of course what Hacksaw said but probably don’t have much room on a late Camaro. Assume you’ve verified the car isn’t periodically pulling straight up out of the beam?
