Sport handling & ride. Lowers vehicle 1.0" Front and 1.3" Rear. The Eibach Pro-Kit Sport Lowering Spring Set improves your vehicle's looks and performance. Pro-Kit Springs lower the vehicle's center of gravity, reducing body roll in the turns, dive under braking, squat during acceleration and give the car a more solid secure feel at all times. Pro-Kit Springs also minimize the ugly fender well gap. 

This kit works on all of the following vehicles:

• Pontiac Solstice
• Pontiac Solstice GXP
• Saturn Sky
• Saturn Sky Redline

On GXP and Redline models, the front springs have a slightly higher (@ 20lbs.) spring rate than the 38123.140 springs.  This spring will be better suited for aggressive/track driving.  On GXP and Redline models, most people are trimming the bump stop 20-25mm.
