Description

IMPORTANT NOTICE: Will not fit Cobra Independent Rear Suspension(IRS).

Dial in your ideal ride quality with the independently adjustable compression and rebound valving of QA1 Proma Star double adjustable coilover systems. They offer the perfect balance of street-ability and performance and are an ideal choice if you plan to use your car on the road and occasionally take it to the track.

With QA1 Proma Star double adjustable coilover systems you will improve overall handling, increase suspension tunability, and gain the ability to adjust ride height quickly and easily for a perfect stance and corner balance your car, maximizing performance. They are easy to install with basic hand tools in the factory mounting locations and does not require the use of a toe link relocation kit.

Coilovers are available with multiple spring rate options to help you find the perfect option for your intended use. The medium springs are great for cars that will mostly be used on the road. The firm option is geared toward track-oriented cars, further reducing body roll under hard cornering, and providing a more planted feel.

Product Overview

Perfect for performance cars and drivers who demand the best in ride quality and handling.
