QA1 Coilover Strut Kit - Double Adjustable - Handling - 300 lb/inch Springs (2005 - 2014 Ford Mustang) - HD05-12300
Sharpen your S197 Mustang's front suspension response with the QA1 Coilover Strut Kit HD05-12300. Designed for 2005 - 2014 Ford Mustang applications, this handling-oriented package pairs double adjustable Proma Star struts with 300 lb/inch coilover springs. It's designed for enthusiasts who want more precise control over suspension movement, improved handling response, and the freedom to tune their Mustang for aggressive street driving.
QA1 uses an inverted cartridge design with a large-diameter shaft to resist side loading during hard cornering and braking. Lightweight threaded aluminum strut bodies help reduce unsprung weight, improving the suspension's ability to respond to road inputs. The handling-oriented spring configuration provides a performance-focused foundation, while adjustable coilover ride height lets you refine stance and suspension setup.
Independent compression and rebound adjustment gives drivers more control than a fixed-damping strut. QA1's accessible 18-position adjustment knob allows tuning changes at the top of the strut tower, helping you refine how the Mustang responds during braking, cornering, and changing road conditions. The HD05-12300 delivers the flexibility to develop a more responsive front suspension without sacrificing the convenience of a bolt-in strut system.
