What is the main benefit of the monotube design in these coilovers?

The monotube design uses a large piston to precisely control rebound damping. It also prevents aeration and foaming, which results in more responsive valving and consistent performance, especially during hard driving.

How can I adjust the suspension settings with this kit?

You can adjust both the rebound damping and the ride height. The rebound has 12 distinct positions, allowing you to fine-tune how quickly the damper returns after compression, tailoring the feel to your driving needs.

Are these coilovers suitable for both track and street use?

Yes, these coilovers are designed to offer a combination of track performance and road balance. The adjustability allows you to optimize grip for the track while also achieving a suitable setup for daily driving.
