Proma Star Strut & Coilover Kits

FOX BODY, SN95, AND S197 MUSTANGS & THIRD GENERATION CAMAROInfographic of QA1 Proma Star Struts

PRODUCT FEATURES & BENEFITS:

  • Inverted Strut Design: The Proma Star strut's inverted cartridge design features a large diameter shaft that resists side loading, improving handling and traction. Its lightweight aluminum body reduces unsprung weight for better suspension response.
  • Adjustable Ride Height: Proma Star strut kits lower your ride 0" to 2" for the perfect stance, from street to track.
  • Tuned Spring Rates: Whether setting up your car for street, drag racing, or handling applications, each kit offers custom tailored spring rates to achieve the ideal ride and performance.
  • Adjustable Valving: Fine-tune your suspension with our single or double adjustable valving options, to meet the specific needs of your vehicle and driving style. 
  • Aluminum Caster Camber Plates: All-new aluminum caster camber plates look fantastic and will really dress up your strut towers, while being significantly lighter than steel and resisting corrosion with a highly durable anodized finish.
