Product Description

The QA1 HS03-12200 is a single adjustable Proma Star front coilover strut kit engineered specifically for 1994-2004 Ford Mustang SN95 and New Edge models - including Base, GT, Cobra, Cobra R, and Mach 1 variants. This Street package pairs the inverted Proma Star strut with a 200 lbs/in 12-inch spring for a comfortable, street-friendly setup that retains the adjustability to firm up for occasional autocross or track use. The inverted cartridge design's large diameter shaft resists side loading for smoother, more consistent performance during hard cornering and braking compared to conventional strut designs.

Single adjustable valving provides 18 simultaneous compression and rebound positions via a single knob conveniently located at the top of the strut tower for easy under-hood access - no tools or steering lock required. Ride height is adjustable from stock down to 2 inches lower via the threaded strut body collar, enabling precise corner balancing for weight distribution tuning. Red anodized aluminum caster camber plates are included for front-end geometry and tire wear adjustment. This kit installs without cutting or welding.
