What is the benefit of a monotube damper design?

Monotube dampers use a larger piston for rebound damping control. This design helps prevent aeration and foaming, resulting in more responsive valving and consistent performance, especially under demanding driving conditions.

Can I adjust the stiffness of these coilovers?

Yes, these coilovers feature 1-way adjustable rebound damping. You can select from 12 distinct positions to control how quickly the damper returns to its extended state, allowing you to fine-tune the handling characteristics.

Do I need to purchase additional parts for installation?

These coilovers are designed to work with your vehicle's OEM top mounts. While the kit includes springs and dampers, it's always recommended to consult the manufacturer's installation guide for a complete list of any additional hardware or tools that may be required.

About this part

Product Details

This set includes a full set of AST 5100 Series STREET coilovers, complete with springs, designed specifically for your 2017-2021 Hyundai i30N PD. These aren't just basic replacements; they're a significant upgrade for anyone looking to fine-tune their car's handling and stance. The true coilover design for both front and rear means you get maximum adjustability and a more performance-oriented setup compared to standard suspension components.

What sets these coilovers apart is their monotube construction. This design uses a larger piston for rebound damping control, which helps prevent aeration and foaming. That means you get more responsive valving and consistent performance, especially when you need it most. You can easily adjust the rebound damping through 12 distinct positions, allowing you to dial in the perfect feel for your driving style and road conditions. Plus, you can independently adjust the ride height, giving you the flexibility to set your car's stance precisely how you want it. The initial spring rates and setup are based on AST's extensive development and testing, providing a solid foundation for everyday use and spirited driving.

These dampers are also rebuildable, meaning if any issues arise down the line, they can be serviced at a certified AST service center, extending the life of your investment. They are designed to work with your car's OEM top mounts, simplifying the installation process. If you're aiming for improved road balance, better grip, and a more predictable handling experience, this AST coilover kit is a well-built option.
