Built around motorsport-derived monotube technology, the 5100 Series offers consistent damping performance, improved heat management, and a sharper, more connected feel than typical twin-tube suspension.\u003c\/p\u003e\n\u003ch4\u003eMonotube Performance Design\u003c\/h4\u003e\n\u003cp\u003eThe AST 5100 Series uses a high-pressure monotube damper design where the oil and nitrogen are separated by a floating piston. This enables a larger internal piston for improved damping accuracy, better grip, and more consistent performance under hard braking and cornering. High-pressure nitrogen helps prevent cavitation, maintaining stable damping behaviour when the suspension is working hard.\u003c\/p\u003e\n\u003ch4\u003eRebound Adjustable Control\u003c\/h4\u003e\n\u003cp\u003eRebound damping is adjusted via a single external knob, allowing you to fine tune the suspension to suit your tyres, road conditions, and driving style. Ride height is adjusted via the threaded body, with AST shock bodies designed to retain maximum stroke even at lower ride heights.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMonotube damper design for consistent performance and improved control\u003c\/li\u003e\n\u003cli\u003eSingle-adjustable rebound damping\u003c\/li\u003e\n\u003cli\u003eHeight adjustable via threaded body\u003c\/li\u003e\n\u003cli\u003eFloating piston design with high-pressure nitrogen to reduce cavitation\u003c\/li\u003e\n\u003cli\u003e14mm internal shaft diameter\u003c\/li\u003e\n\u003cli\u003e44.5mm inverted strut shaft design for strength and rigidity\u003c\/li\u003e\n\u003cli\u003eSteel shock bodies for durability\u003c\/li\u003e\n\u003cli\u003eLow-friction seals for improved sensitivity\u003c\/li\u003e\n\u003cli\u003eAdjuster knobs permanently mounted on the dampers\u003c\/li\u003e\n\u003cli\u003eRubber bushings for eye-type shock mounts\u003c\/li\u003e\n\u003cli\u003eRebuildable and serviceable construction\u003c\/li\u003e\n\u003cli\u003eOptional custom valving available\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eOptional Upgrades\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSpherical top mounts\u003c\/li\u003e\n\u003cli\u003eDLC coated shafts\u003c\/li\u003e\n\u003cli\u003eDDP piston (double digressive)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M2 F87 (Pre-LCI)\u003c\/li\u003e\n\u003cli\u003eBMW M2 F87 (LCI)\u003c\/li\u003e\n\u003cli\u003eBMW M2 F87 Competition\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AST Suspension","offers":[{"title":"Default Title","offer_id":51902933532965,"sku":"ACU-B2104SD","price":5440.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0918\/2943\/6709\/files\/N2004S-2_6b855bd3-5f58-40fc-b148-e53e1a3c990e.jpg?v=1768526814","url":"https:\/\/www.chicaneaustralia.com.au\/products\/ast-5100-series-inverted-coilovers-bmw-m2-f87-pre-lci-lci","provider":"Chicane Australia","version":"1.0","type":"link"}
