QA1 Proma Star coilover strut kit HS01-12200 delivers front suspension performance for 1979-1993 Ford Mustang Fox Body models.

Ride height adjustment and damping tuning allow precise control over handling, cornering, and vehicle stance with bolt-in simplicity.
Key Features

- Single Adjustable Valving: 24-position compression adjustment tunes damping from firm track settings to compliant street ride without removing the strut
- 200 lb/in Tuned Spring Rates: Progressive rates balance street comfort with performance grip, reducing body roll and nose dive for sharper response
- Ride Height Adjustability: Threaded spring perch and body collar provide 1.5-2 inches of drop for custom stance while preserving suspension travel
- Lightweight Caster/Camber Plates: Billet aluminum plates included for accurate alignment, caster gain, and reduced bind on lowered setups
