Are there any other harder bushings available for the Max?
I already have the endlinks and the front sway bar.
Has anyone tried the control arm ones from Courtesy?

 

Then you allready have them in the rear control arms and front sway bar, and motor mounts on the SE model. Also if you have the SE model with auto, you have liquid filled, electronically controled rear motor mount. Otherwise they are all Polyurethane.

the one courtesy sells are made by Energy Suspensions, and are winning of many awards in quality and durability tests, and are known to last up to 8 times longer with normal driving, and reports of lasting 4 to 5 years of heavy abuse before needing replacement!
