having the right shocks will really help weight transfer as well.
the best "comprimise" for me would be a VERY free pivoting sway bar.
it would take some engineering to do, but it should help.
removing the bar is a bit too much for me, I'll maybe disconnect it at the track, but I like burning corners a bit too much to remove it.
my old buick turbo has big ol sway bars on it and poly bushings and wide tires, it's still like a shopping cart with a bad wheel when comparing the handling to the z06, but it's sure better than stock!!
two things to keep in mind, you setup a car to handle well, or hook well, and stiff springs/shocks/bars that go well with handling, don't help the hook at all.
I like my vette biased more toward handling, but make the "concession" using nitto 335s. not as good as an M&H or a BFG to be sure, but sticky enough to not spin so bad, and a stiff enough sidewall to handle well.
good point you made about the sway bars, just DON'T get rid of the back one as it can help plant the tires and even out the torq a bit.
we found that bigger bars can do well and would likely work on the IRS too, never validated that?? what do you think?

I must be missing something here, other than weight how does removing the front sway bar help you? In a straight line don't the front wheels move the same with or without a sway bar? Isn't it designed so that when cornering it twist to transfer the energy to the oposite side?
I'm confused!

its hard to get a car to run 9's... and handle like a F1 car...get 30 mpg and still have all the creature conforts like a/c.... unless you are Nick... 
I live with the front swaybar off, and the front end is looser than stock... but I am also not kicking myself in the a$$ when I lose to someone with less HP cause I am spinning down the track

I have read so many threads about traction issues and trying to find the right street tire...
Do you guys still have your front sway bar connected?
Traction is about weight transfer, (and some right pedal control)... I am able to drive my tti-x at 18# on the street on 315x40x18 BFG drag radials (@25-28#) and I do not have traction issues.

I have ran the 315 BFG's in the past. On my old nitrous setup those tires needed to be replaced in two to three weeks. They did grab like a ****.. I never tried them at full tilt on the spray though. I only ran them on about 650rwhp..

At the track maybe but for the street I'd prefer having it on! IMHO!
It certainly helps if it is off at the drags!
weight transfer!
Thanks,Matt
