Watch how easy it is to make a muscle car handle like a new car. Hotchkis took a 1970 Buick Skylark GS and added the full Hotchkis TVS. Hotchkis offers replacements for most muscle car suspension and upgrades this vintage Buick with Hotchkis springs, sway bars, shocks, control arms, ball joints, tie-rod ends, rear air bag kit and even a new quick ratio steering box.
