Dave,

With these springs will i need to use 3rd party camber adjustment or can i get it back in spec?

Can you send me a price for the combo?

 

hey guys - I don't have those sway bar specs available, and I didn't get the information from Progress Tech either. You could try contacting them directly to see if they would provide it for you.

These spring do not give as much of a drop as say coil overs. The drop average is around 1.2". so you could get an allignment done and get it pretty close to spec. You may have a little extra negative camber in the rears, which is not horrible, and will actually provide better handling. The only issue with that would be uneven tire wear, as the insides of your tires would wear faster. So you'd want to rotate them more frequently.
Sometime the price you pay for performance!

 

springs and sway bars sale available again. sale prices updated on our site. thanks all.
