What does 'double adjustable' mean?

Double adjustable coilovers allow you to independently adjust the rebound and compression of the shock. This lets you fine-tune the suspension to your driving style and road conditions. Each adjustment has 18 clicks, giving you a wide range of settings.

How much can I lower my Mustang with this system?

This coilover system lets you adjust your Mustang's ride height from the factory stock height down to 2 inches lower. This allows you to achieve a more aggressive stance while maintaining proper suspension geometry for predictable handling.

Is this a difficult system to install?

QA1 designed this system as a direct bolt-in replacement for your factory suspension components. No welding or cutting is required, making it a straightforward installation with standard tools. Refer to the manufacturer's installation instructions for specific procedures and torque specifications.
