AST RIV-B2115SD 5200 Series Coilovers for BMW G80-G83 M3 and M4 with 2-Way Adjustable Dampers

Description

Designed for serious driving enthusiasts, the AST RIV-B2115SD 5200 Series Coilovers deliver exceptional performance and customization for BMW G80-G83 M3 and M4 models from 2021 to 2023. These coilovers feature a monotube design with external reservoirs, providing superior heat dissipation and durability during intense driving sessions. The adjustable ride height allows you to fine-tune your vehicle’s stance for optimal handling and aesthetics.

The 2-way adjustable dampers enable precise control over rebound and compression settings, with 12 distinct positions for each adjustment. Rebound control influences the extension of the dampers, affecting responsiveness and stability, while compression adjustment manages how quickly the suspension compresses when encountering bumps or turns. This flexibility allows you to optimize your vehicle’s behavior for street, track, or spirited driving.

The inverted strut design enhances strength and stability under heavy side loads and braking forces, making these coilovers ideal for high-performance applications. Both the front and rear dampers feature a monotube coilover construction, with adjustable spring rates for further customization. The kit includes camber-adjustable front top mounts and solid rear top mounts, providing additional wheel alignment options to maximize grip and cornering performance. For vehicles equipped with Electronic Damping Control (EDC), a separate delete kit is recommended to ensure full functionality of the coilovers.

Whether you’re looking to improve handling, reduce body roll, or customize your ride height, the AST 5200 Series Coilovers offer the versatility and performance necessary for competitive or enthusiast driving. Engineered and built by AST, a trusted name in motorsport suspension technology, these coilovers are designed to meet the demands of high-performance driving on the street or track.
