So, do they have to be at least 141 TW or is it greater than or equal to 140?

I'm not going to make this one, but it would probably be good to clarify in case you meant 140's are out and you are going with the new 200 TW rule.

Looks like we'll not see you guys this weekend after all. I'm going up tomorrow to check things out, and that is the tnt day.
I gotta work one day this weekend and the club member I'm going with has plans Sunday so that's that.

To be honest, I'm kinda burned out this year and ready for the of season. Car is hopefully going to start getting ripped apart over the next week and get the gear box over to Mike soon.

Question for tomorrow. ...not knowing where to start on air pressure like started with the pressure of my old tires 44 front 38 rear that doesn't work so I changed to 40 front 40 rear this seemed to be better as now the ass end wants to come around not experiencing this for 8 months it's taking me time to get use to it. I can control most of it with the throttle. Tires are rolling over right on the indicator mark. Since we are getting 3 or 4 runs should I try more or less air front or rear to help?

40 sounds high for the back, Paul. Unless you want it to rotate.

Paul,

Did you ask Corsaro on the Camaro forum what tire pressures he was running on his car?

The other way to check inflation pressure is the temperature profile across the tread. A probe type tire pyrometer is the best, but you can get a fair idea with an IR thermometer that you can buy for about $50 at an auto parts store. You need to measure the temps as soon as possible after a run. Start at the outside of the front tire that works the hardest, the left front on a mostly clockwise course or the right front for counter clockwise. Then measure the center and inside of that tire. Do the same for the rear on that side and then measure the other side tires. If the center temperature is less than the average of the inside and outside, you need more pressure and vice versa. Ideally, the inside edge would be hotter than the outside, but that's unlikely in a street car where camber adjustment is limited.

It's hard to do this at an event without a crew person. Also, if you're over driving, the outside edge is going to get quite hot and throw the measurement off. That's a driving issue, though, not tire pressure. I have a clover leaf interstate interchange close to the house. A few passes around that when the traffic was low driving at the point where the tires were just thinking about making noise and then measuring the profile across the tread was what I did to get the pressures in the ball park.

I agree with Mark, 40 psi seems high for the rear.

Also, invest in a two gallon pump up sprayer and fill it with water. If you overheat the tires, it will shorten their life.

Welp, thanks to Johnee, shocks are now "unbotched". Hope I don't have to change the rear rebound soon. Have to drop the shock to do that.

It's too much to post but it will be interesting telling y'all what I did wrong and what the result was.

Talk to Mark Andy about the rebound adjust. I'm pretty sure he has a way around not dropping the shocks.
