Lower your ride, improve your handling, and get control over your suspension. The most versatile choice for suspension on today's market. Go from the strip to the street to the show floor with the push of a button. Our kits are designed to give you maximum performance. Want to adjust your spring rate? No coilover will ever offer this option! Adjust your spring rate with the flip of a switch or use our optional "Auto Pilot" digital controller to set it and forget it. When style matters just as much as performance, our air kit will get you down... as low as you want to go. Wheel gap never helped anyone win a car show! Tuck those rims up where they're supposed to be. Combined with our F.B.S.S. air management system (included) this kit will set you on the ground, let you clear speed bumps, and get in and out of driveways without scraping your ride. Not to mention the remarkably smooth ride that air provides.
