Product Overview
The QA1 Proma Star Strut is a perfect choice for your Mustang. It’s ideal for both street and race applications, thanks to its lightweight inverted strut design. This allows you the best possible performance and handling out of your car, regardless of your driving style.

Inverted Strut Design
A major advantage of the Proma Star strut is its inverted cartridge design. Unlike conventional designs, its large diameter shaft resists side loading, ensuring smoother and more consistent performance during hard cornering and braking. The lightweight threaded aluminum body offers reduced unsprung weight improving suspension responsiveness, leading to better handling and traction.

Double-Adjustable Valving
Double-adjustable struts are the ultimate in performance suspension. Independent tuning of rebound and compression allows you to fine-tune the handling of your Camaro for any driving condition. Adjustments are made under the hood with an easily accessible 18 position knob at the top of the strut tower. This is the choice for drivers who want the absolute best possible handling and performance
