So I'm in the process of upgrading a couple of suspension components on my Envoy, which so far has included progressive springs and Bilstein shocks. I'm looking to upgrade the stock 24 mm sway bar in the rear, and as it stands, I've got 2 options: Hotchkis 27 mm Addco 29 mm The stock front sway bar is a 34 mm, so there's no point in upgrading it. The good thing about the Hotchkis is it comes with poly bushings for both the front and the rear bar. They'll need to be greased up real good to prevent squeaking however. That being said, because of the size of the front bar, there's quite a bit of understeer in this application and I'm not quite sure if 2 mm will make all that much of a difference if I opt for or against the Addco vs. the Hotchkis. Any takes?
