What is the benefit of a monotube damper design?

Monotube dampers, like those used in the AST 5100 Street Coilovers, feature a larger piston. This allows for more precise control over rebound damping and prevents aeration or foaming, resulting in more responsive valving.

How do I adjust the ride height and damping on these coilovers?

These coilovers allow for adjustment of both ride height and rebound damping. You can fine-tune the rebound with 12 distinct positions to achieve your desired road balance and handling characteristics.

Can these coilovers be serviced if needed?

Yes, the AST 5100 Street Coilovers are rebuildable. If any damage or issues arise, they can be addressed at a certified AST service center.

About this part

Product Details

If you're looking to get the best road balance for everyday use in your 2017-2021 Renault Megane 4 RS B9 FWD, the AST 5100 Street Coilovers are a solid option. These coilovers are built to help you maximize grip by giving you control over your car's rebound and ride height. They come complete with springs and are designed to work with your car's original top mounts, making installation more straightforward.

The AST 5100 Street Coilovers feature a monotube design, which means they have a larger piston for better control over rebound damping. This design also prevents aeration and foaming, leading to more responsive valving. You can adjust both the rebound damping and the ride height independently. The rebound adjustment lets you fine-tune how the dampers extend, allowing you to achieve the ideal road balance for your driving needs. With 12 distinct positions for rebound adjustment, each setting offers a noticeable change in feedback and the overall driving experience. The spring rates and initial setup are based on AST's extensive development and testing, providing a strong foundation for performance.

These dampers are also rebuildable, meaning if any issues arise, they can be serviced at a certified AST service center. This set includes both front and rear dampers in a true coilover design, prioritizing adjustability and performance. By choosing this setup, you gain more control over damping settings and ride height, typically resulting in more consistent and predictable handling characteristics.
