QA1 90-93 Ford Mustang Proma Star Coilover Strut Kit Double Adjust 150lb/in.

QA1 is well-known for making performance suspension components, and this Proma Star Coilover Strut Kit is a prime example of their work for the 1990-1993 Ford Mustang. If you're looking to dial in your Mustang's suspension for drag racing or spirited street driving, this kit offers a significant upgrade over stock. It allows for precise adjustments to both compression and rebound damping, giving you the control to fine-tune your car's handling and launch characteristics.

This kit features a double adjustable valving system, meaning you can independently set your low-speed and high-speed damping. This is crucial for drag racing, where you want to control body roll during the launch and ensure stability at speed. The inverted design of these struts is a smart move; it places the larger bearing and seal on the bottom, which helps to resist side loading and extend the life of the strut. Plus, they're made in the USA and are surprisingly lightweight, which can contribute to better overall performance.

Installation is designed to be straightforward, as these are a bolt-in application, meaning you won't need to do any welding or major modifications to get them fitted. This kit comes with a 150 lb/in spring rate, which is a popular choice for Mustangs looking for a firmer ride and improved weight transfer during acceleration. While this kit is built for performance, it's always a good idea to consult the manufacturer's installation guide for specific setup and alignment recommendations to get the most out of your new suspension.
