QA1 Proma Star Double Adjustable Coilover Strut Kit - 150lb/in - Ford Mustang 2005-2014
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2005-2014 Ford Mustang (Base, GT, Boss 302, Bullitt, and Shelby GT500 models).
The QA1 Proma Star coilover strut kit is engineered to provide professional-grade suspension tuning for S197 Mustang owners.

With double-adjustable valving, you can independently dial in compression and rebound to match your specific street or track requirements.
This kit includes a 150lb/in spring rate, ideal for balancing ride quality with improved mechanical grip. The package is completed with lightweight caster camber plates to ensure precise alignment geometry and full ride-height adjustability for the perfect stance.
