I love my single bar built by Troy Henderson. Works awesome, doesn't upset the car, way easily adjustable and it just works period. He built the bar, installed it in his car to make sure it fit, and then sent it to me and presto...it fit like a glove. The welding is second to none and it a quality built piece. He was also telling me if I ever wanted to upgrade to an anti-roll bar to call him and he will make me a new upper support bar that doubles as an anti-roll. No need for that yet because I don't seem to be having any trouble with it. Pretty trick unit.
