When to shift
I am not a speed demon, I don't often drive hard off the line and rarely drive over 90. I am just wondering if I wanted to go 0 to 140 as fast as possible at what rpm would I shift at for each gear?
Do you racers out there get near red line for each gear? Curious to see what you guys think.

my car doesnt shift well at high rpms, very difficult to get a smooth shift, i wonder if its clutch related
Im about 570 at the crank it drives smooth as butter during regular, or slightly spirited driving

I prefer cruising at high speed. I was on 85 south in North Carolina a few weeks back and a pick up, a C5 and me in my C6 were cruising 95 to 100 for about seventy five miles taking turns being the lead car. That was fun!

Max torque to rear wheels is achieved by going to redline in 1st and 2nd. To figure out this for yourself find torque curve for your engine, multiply torque by transmission gear multiplication, shift when torque is higher gear is higher than torque in lower gear.

What tune on the car?
If stock, then you notice that the motor will want to go flat around 5.5K, and the torque is dropping off around 5.4K as well.
So this would be your best shift points for shift, even on a stock LS7 motor. Hence the LS7 will rev out at 7K, but since it's going flat long before that, that extra RPM is really just a saver for when you are coming out of a corner and don't want to shift until your down with the corner instead.
On the other hand, if the motor has been tuned to pull hard all the way to red line, then it would be just before redline that you would want to shift instead.
As for 140 MPH, that only a few gears, since most C6's in 5th gear will take you up to 175mph before the motor rev's out in 5th.

I get the feeling some don't think I know how to drive my car, I know how to stomp on it. I guess I was wondering if it is better getting into second gear at say 4500 rpms than going to red line, same thing for 2-3, 3-4 etc.

Sorry, my humor is very dry and my answers are full of snark, yet always based on facts.
Did you watch the video I posted?
Have you tried your 4500 rpm theory out and compared it to running up to 6500? Even the butt dyno will tell you the answer.
Mr. “Hence” knows his stuff when it comes to C6 repair, but he’s wrong on when to shift one.
Running on the expressway at 100 isn’t exactly extreme. Some people call that commuting. (**** I did it again, I can’t help myself)

I had to recallibrate my entire driving style when I bought my GS. I came from a lifetime of muscle cars where the party was over by 4500 rpm max. With the LS3 that is when the fun is just beginning. I have my Dashlogic programmed to sound an alarm beep @ 6200k rpm, so I can shift just before redline.
I really was just being curious about shifting at what rpm's. I doubt I will ever run through the gears at red line. Does that get me kicked out of the Corvette family now?.
