Drag Racing Tech - T/A & 21mm sway bar or Anti roll bar??

I`m blowing the tires off the line with this 4400 stall, even with the stock 3.23`s and 26x11.5-15 ET Streets. (And a motor that only put down 377 rwhp on a Mustang Dyno.) After babying it for the first part of the in fear of the ten bolts life, I`ve dropped the tire pressure to 13.5 lbs. and have been doing a pretty descent burn out, but she`s still spinning bad and twisting out of the hole. Right now the suspension is all stock accept for a BMR adj. panhard rod and stock boxed LCA`s w/poly bushings. So, i`ve ben thinking about what the most cost effective way to go for a rear suspension set up.
I was thinking either the combination of a non-adj. T/A and a 21mm rear sway bar or just leaving everything alone and installing a Wolfe anti-roll bar?
What do you guys think?

Thanks,
Eric
