Bring modern performance and precision to your classic Mustang with QA1’s Level 2 Full Vehicle Handling Kit. Designed for 1964–1966 Mustangs, this system takes everything from the Level 1 package and adds QA1’s triangulate rear 4 link coilover conversion as well as double adjustable coilovers for independent tuning of compression and rebound — delivering the next level of control, comfort, and confidence whether you’re carving corners or cruising. ENGINEERED FOR MODERN HANDLING Factory suspension geometry simply can’t keep up with modern expectations. QA1’s Level 2 system replaces outdated leaf springs and stamped arms with performance-tuned components that improve cornering, traction, and stability. The included triangulated 4-link rear system eliminates wheel hop and improves rear-end control under acceleration and braking all while providing a smoother, more predictable ride. HANDLING YOU CAN DIAL IN Double adjustable coilovers allow independent control over compression and rebound, so you can fine-tune ride quality and performance for your exact driving style - whether that’s highway cruising or weekend corner carving. BUILT FOR EASY INSTALLATION The front suspension is a direct bolt-in upgrade, retaining the factory shock towers for a clean fit. The rear 4-link system requires welding, but QA1’s self-fixturing brackets simplify alignment and ensure precise geometry. Every part is designed for builders and DIY enthusiasts alike — with everything included to overhaul your car’s stance, ride, and handling.
