The challenge with respect to bracket racing, is cutting a good light, and playing a good top end game.

I couldn't agree more... 100% ...
Eric... could you "Imagine" how tough it would be if there were 7 or 8 drivers who could "HIT" the tree as good as me...

I finally put the car in the 10's this weekend. I have a 2009 Z51 with a 6spd running 345/30-19 NT05Rs out back at 17psi hot and CTS spares w/ 185/50-18's up front. I'm also on the stock clutch, gears and motor.
I got the 60' into the 1.7's for the first time this trip. I'd like to get it into the 1.5-1.6 range, but it's hard to keep the RPM's high enough to get out of the hole hard w/o spinning... I didn't bog on this one, but it defnitely feels like the car would 60' better if I got through the first few thousand rpm of acceleration faster.
Any suggestions or comments?

I'm helping a couple other guy's in other threads as well, but if I might make a suggestion....
IF you are looking for the best ET you can get, switch to a C5 Z06 17x9.5 front wheel and get a set of 275/40/17 or 315/35/17 Hoosier drag radials. These tires are about as sticky as you can get for a DOT tire, weigh a considerable amount less than the 19x12/345 NT05R combo you are using, and are a bit shorter to help your rear gearing.
Your ET will come from your 60' and 1/8 splits, so that's where you need to concentrate your energy and effort.
Last weekend, I took a basically stock C6 Z06 with 60K miles on the stock original clutch into the 10's with these Hoosiers....oh, and a DA of +2028 ASL
I pulled consistent 1.59's on 3 out of the 5 passes (got booted ), and on my last pass, if I hadn't short shifted the 3-4 shift, may have gone into the high 10.80's (ran 10.97).

60.1* , 29.88 in Hg barometric pressure, 41% humidity
Density Altitude: 2028 feet
Relative Density: 94.2 %
10.9504@128.71 MPH on a 1.5987 60'
Backup pass would've been faster still, as I had a PB on the 60' (1.5934) and a faster 1/8 split and better MPH than my previous run, but I short shifted 3-4 on this run.
I didn't run it out the back door for this pass, so that's why the MPH is down 5+ MPH...
10.9706@123.32 MPH on a 1.5934 60'.

Please note that the 315/35/17 M/T's rub on the outer edge of the fender on standard c6's...on the wide body they fit great and I find they have better traction than the 275's.

Yep.....if I hadn't gotten such a great deal on the 315's I would have purchased the 275's even for my Z, as they are a touch bit lighter and I haven't had traction issues yet.....but I don't have your higher RPM launch.

I notice a surprising difference, the 315's help my launch quite a bit. I'll spin 275's when 315's bite with the same high rpm launch.

I am not an expert, but just thought I noticed a couple of things that might help you getting hooked up better.
