Description

PRODUCT OVERVIEW QA1's Handling Kit is the ideal suspension upgrade for '70-74 Camaro and Firebird owners wanting improved street and track performance. This complete solution replaces the front and rear suspension with adjustable coilovers and a 4-link setup, optimized for wider wheels and tires, plus a custom QA1 9" rear housing. SIGNIFICANT HANDLING IMPROVEMENTS Experience superior handling with lightweight tubular control arms, low-friction ball joints, and polyurethane bushings that improve geometry and reduce flex. The adjustable four-link design eliminates wheel hop, increases traction, and provides tunable handling. Front and rear sway bars and subframe connectors reduce roll in tight corners. OPTIMAL STANCE QA1's coilovers and tubular 4-link offer up to 2 inches of front adjustability and 1.25 inches in the rear for the perfect stance, and shift components inward for extra clearance with wider wheels.
