I just lowered my 99 SS Convertible with a set of DMS springs and new factory shocks (yes, I should have gotten bilstiens but I had then from my last Z28). Anyway, I need to know if I need a four wheel alignment or just a two wheel (front) alignment. As far as I know only the front is adjustable from the factory, is this correct?
Also, I didn't get LCA relocation brackets, do I have to have them before I get the alignment done?

Thanks

 

These cars only have ft end alignment adjustment. However if u've added an adjustable PHR, adjustable trailling arms, or an adjustable Torque arm, then u'll have to adjust/tune the set up.
