Product Overview

Product Overview Ditch those clunky leaf springs and take control of your F-body with QA1's coilovers and triangulated 4-link. This upgrade improves ride quality, enhances handling performance, and enables you to dial in the perfect stance. With the added benefit of accommodating wider wheels and tires, this kit is the ideal solution for your car. Achieve the Perfect Stance. Leaf springs limit your ability to achieve the perfect stance on your Camaro or Firebird. Upgrading to QA1's coilovers and a tubular 4-link provides +2 to -3 inches of ride height adjustability, letting you dial in exactly the look you want. Fit Wider Wheels & Tires Designed to work with both standard and mini-tubs, this system offers generous clearance for up to 11-inch-wide wheels on 67-68 F-bodies and 12-inch-wide wheels and 335 tires on your 69. This results in a significantly more aggressive stance and improved traction and performance. Note: Achieving maximum wheel and tire width will require mini tubs.
