Description

Product Overview The QA1 Level 2 Handling Kit is a serious upgrade for people seeking a better handling and performance from their Fox Body Mustang. The kit includes a lightweight tubular K-member, control arms, boxed trailing arms, sway bars, and front and rear double adjust coilovers. Tubular Front K-member These are designed to save weight and free up room in your engine bay. Weighing only 25lbs., it's 50% lighter than stock K-members and boasts improved geometry and durability. Interchangeable engine mounts, sold separately, offer flexibility for running factory or late model engines including Coyotes. Inverted Front Struts and Rear Coil-Overs Front struts feature an inverted cartridge design, large diameter shaft, and lightweight aluminum body for improved suspension performance. The lightweight, high-travel springs with proven spring rates are optimized for improved handling and street performance. These kits offer up to 2" lower than stock ride height adjustment to dial in the perfect stance. Double-adjust rear coilovers are great for both street and trackday cars looking to further tune their rear suspension. Lightweight Caster Camber Plates Aluminum caster camber plates improve Mustang handling and performance. Lighter and sleeker than steel, they offer precision adjustment to fine-tune suspension geometry for optimal performance. Tubular Control Arms, Trailing Arms and Rear Sway Bar Tubular control arms, trailing arms, and sway bars solve flexing and bushing bind. Easy, Bolt-In Install Made in the USA Fitment Notes Engine mounts not included. QA1 offers several mounts for factory engines as well as popular engine swaps which are sold separately. For Fox Body: Kits for early year range Fox Bodies (1979-1986) will retain factory track width (narrow.) Kits for late year range Fox Bodies (1987-1993) will retain track width of the factory '87-'93 V8 cars (wide.) Not compatible with Cobra IRS
