It is assumed that if your a Stage 2 Roush,your car has been lowered?I may be wrong but on my Roush ,I've added an adjustable Panhard bar...I have not yet added lower control arms however(from the posts I have read)it's a good idea .Then get your car aligned.
I meant Adjustable LCA's.Read some of the threads on suspension in the threads.I have learned alot and still am amazed at the caliber of knowlege being shared.Just curious,how do you know your aligment is off?Are your new tires worn out already?
