If you Tune it you better add these
This change this car 100% for the better. with the Eibach pro spring kit it makes the car safe after you tune it. It also needs a better, break pad, fluid and lines. I run, Steel braided break lines, TQ700 fluid and portorfiled pads. Great upgrade!
Plated to the ground
This Eibach Kit is excellent in helping reduce the roll in the chassis. I added these with a Eibach Pro Spring kit and a RP chassis brace and ZZP Trailing arm links. The handling is absolutely amazing. A must if you add HP and TQ to this car. 2013 ATS 2.0T
