Look into getting a set of lower control arm relocation brackets and upgrade the torque arm. The stock LCA angle is setup for driveability not hard acceleration and is prone to wheel hop. Midwest Chassis and Performance makes some nice products the will bolt right in. Otherwise BMR, UMI, Sphoon, and Madman Racing all have nice products. As set of subframe connectors is pretty much a must on any subframe car. The front sway bar is not helping with weight transfer and a set of adjustable front shocks would help. Just upgrading the suspension should lower the cars et. Unfortunatly there's not alot of info on seting up a TA suspension, you'll find all kinds of info on 4 links and ladder bars! As a basic understanding I'd recommend these books:
