Suspension help.

I'm ASSUMING you have "GT" springs in the rear, RIGHT?

REAR sway bar still in tact? First thing I would do is drop the ride height on all 4 corners, if you haven't done so already. LOW center of gravity is what you're shooting for here. Maybe throw a few more PSI into the air bag. Low center of gravity automatically lowers your "instant center", which is WAAAAY important on the launch.

What kind of shocks/struts are you running? 4cyl. springs up front, but what's out back. Are they GOOD???

Rubber or Eurothane bushing on those control arms? EVERYTHING back there needs to be solid spherical bushings, or at least eurothane.

If all that's good, next thing I'm looking at is an anti roll bar.

Yeah GT springs in the rear. 04GT stock shocks and struts.

Seriously lower the car? I always heard that a lowered car killed weight transfer to the rear wheels.

well the typical lowered cars are the ones with stiff "handling" springs, which will kill weight transfer

go take a look at any of the small tire classes in NMRA or FFW. Do you see any RS, REN, outlaw guys with their cars all jacked up in the air like the typically bracket racing hillbilly? No. Why? Because their suspension is working.

do like the jester said and try a few more psi in the airbag. also, how much tire pressure are you running? Is the stock rear sway bar still there?
You can try a few other things too. Adjustable strange shocks are cheap, and can be very helpful when dialing in the suspension. Also, antisquat is something that needs to be addressed, likely with the lower control arms. Are those granatelli arms the black bent tubular ones with the adjustable spring perch? If so, then first inspect them for being busted, lol, cause I've seen many that way.
