Product Overview QA1's Level 3 Handling Kit is a complete solution for X-body owners looking for ultimate track-day performance. This complete solution replaces your entire front and rear suspension, optimizing handling performance, while still maintaining comfort on the street. The coilovers offer adjustable ride height, while the rear suspension was optimized for wider wheels and tires. Bind Free, Light-weight Front Suspension QA1's tubular front control arms stand out as some of the lightest available in the market. When paired with QA1's 4-way adjustable MOD Series coilovers, and tubular front sway bar, this kit offers plenty of control. Achieve the Perfect Stance Upgrading to QA1's coilovers and a tubular 4-link provides 0 to -2 inches of adjustability in the front and +2 to -3 inches of ride height adjustability in the rear. Fit Wider Wheels & Tires Designed to work with both standard and mini-tubs, the rear system offers generous clearance for up to 315mm tires. Note: Achieving maximum wheel and tire width will require mini tubs. Improved Performance and Stability 4-way adjustable MOD shocks help drivers find grip in any setting. They make it easy to adapt to different events like autocross, road courses, speed stop challenges and more by changing out valve packs in minutes. It's simple to go from race-oriented suspension to comfortable street driving. Easy, Installation & Adjustment Thoughtful design meets effortless install with a completely bolt-in front suspension and a 4-link requiring minimal welding. You'll experience a painless setup process, where adjusting ride height, pinion angle, or wheelbase is as simple as a few tweaks - no link removal required. No modifications to floor pan required.
