AST Suspension ACU-R2101S 5100 Series Street Coilovers for Renault Twingo 2 RS

The AST Suspension ACU-R2101S 5100 Series coilover kit delivers high-performance suspension designed specifically for 2007-2014 Renault Twingo 2 RS models. This complete coilover system combines precision engineering with street-friendly adjustability to maximize grip and enhance driving dynamics on both public roads and track days.

Performance-Driven Monotube Design:

Built with AST's proven monotube damper construction, these coilovers feature a large piston design that provides superior control over rebound damping. The monotube design eliminates aeration and foaming, resulting in more responsive valving and consistent damper performance. High-pressure nitrogen gas separation ensures maximum damper sensitivity and control under all driving conditions.

Key Features:

• 1-way adjustable rebound damping with 12 distinct positions for precise tuning
• Complete coilover design for front and rear with included springs
• Designed to work with OEM top mounts for straightforward installation
• Independently adjustable ride height without compromising spring preload
• Rebuildable dampers serviceable at certified AST service centers
• Low-friction seals for smooth operation and extended service life
• Adjuster knobs permanently mounted on dampers for easy access

Engineered for Street and Track:

The 5100 Series strikes the perfect balance between street comfort and track performance. Spring rates and damper valving are rooted in AST's extensive development and testing process, delivering optimal performance right out of the box. Individual preferences can be fine-tuned by adjusting the rebound knob or altering ride height to achieve the ideal road balance tailored to your specific driving requirements.

Each adjustment position delivers distinct feedback and a unique driving experience, allowing you to control the return to extension of your dampers and maximize chassis control. The coilover design offers superior adjustability for both damping settings and ride height compared to traditional shock and spring setups, providing more consistent and predictable handling characteristics.
