Eibach Pro-Kit Performance Springs. Pro-Kit lowers your car's center of gravity, reducing squat during acceleration, body roll in corners and excessive nose-dive under braking. When combined with Plus-1 or Plus-2 wheels and tires, the Eibach Pro-Kit is the finishing touch to a winning recipe for performance.
I installed on my 2010 Chevy Cobalt. Excellent ride height. Not bouncy or rough. Gave a more aggressive stance than factory look. I recommend changing your struts and shocks while you are at it.
