The stock Sonic suspension is so terrible that it feels like you will lose control at well less than 100 mph. This is a kit that uses GM's high performance front struts, rear shocks, and front bump stops along with our ZZP Sonic Lowering Springs to dramatically improve the ride height and stability of your Sonic. The struts, shocks, bump stops are GM upgraded, so they are better than what the car came with from the factory. This is the step up from the "RS Handling kit" that GM sells.

Includes:

• GMPP front struts
• GMPP rear shocks
• GMPP front bump stops
• ZZP lowering springs
