QA1 designed their HK43-FMM4 Handling Level 3 Suspension Kit as a serious upgrade for the 1994-2004 Ford Mustang. This kit includes a lightweight tubular K-member, control arms, boxed trailing arms, sway bars, as well as front double adjustable coilovers and rear MOD Series coilovers.
The tubular K-member is designed to save weight as well as 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.
The front struts feature an inverted cartridge design, large diameter shaft, as well as a lightweight aluminum body for improved suspension performance. The lightweight, high travel springs with hand selected spring rates are perfect for flat cornering autocross and road race Mustangs.
This kit offers up to 2" lower than stock ride height adjustment to dial in the perfect stance for your car.
MOD Series rear coilovers provide competition cars with an unmatched level of tunability and control. Tubular control arms, trailing arms, as well as rear sway bars solve flexing and bushing bind, allowing smoother suspension movement, reduced body roll, and better traction in the corners.
