I'm a big fan of STR.T's. For the price, they're unbeatable. I got my set last year from Tunersports.com for $315 shipped to my door.
The panhard bar allows you to recenter your car's body over the axle, because once you lower the car via springs it will shift same laterally. An un-centered car throws off handling and as such an adj. panhard is required to center it.
So can i run the shocks on stock struts then upgrade the struts later?
