Rebound, low-speed compression and high-speed compression can be set separately, providing a more detailed compression adjustment than the two-way 5200 system.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0276\/7375\/5750\/files\/ast-coilover-technical-overview.png?v=1791459751\" alt=\"AST coilover technical overview\" loading=\"lazy\" style=\"width:100%;height:auto;\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDamper design \u0026amp; adjustment:\u003c\/strong\u003e The high-pressure monotube dampers use inverted front struts and remote reservoirs. Both compression controls are located on the reservoirs, with rebound adjusted independently. Low-speed and high-speed refer to the damper's movement rather than road speed; the settings address different suspension inputs, not separate driving-speed modes. Rebound affects resistance during extension after compression.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMounting, supplied equipment \u0026amp; reservoirs:\u003c\/strong\u003e Springs and camber-adjustable front top mounts are supplied. The camber adjustment changes the front alignment at the strut mounting and is distinct from damping and ride-height adjustment. RAC-B2102SD is the three-bolt pre-LCI application and RAC-B2106SD is the five-bolt LCI application. \u003cstrong\u003eDrop links are included\u003c\/strong\u003e with both kits. AST's rebuildable construction allows the dampers to be serviced during their working life. External reservoirs need a secure mounting position and hose routing that remains clear throughout steering and suspension movement. \u003cstrong\u003eReservoir mounting brackets are optional accessories\u003c\/strong\u003e. Wheel and tyre clearance should be checked for the car's actual wheel specification and chosen ride height.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation \u0026amp; setup:\u003c\/strong\u003e For cars fitted with factory Electronic Damper Control, Clubsport Garage recommends coding out EDC when installing non-electronic coilovers, where supported. A compatible KW EDC cancellation kit is a separately available hardware alternative. The replacement dampers remain manually adjusted. Final ride height and alignment should be established as part of the installation, before developing the damping settings around the car's intended use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eFurther information below.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"AST Suspension","offers":[{"title":"Pre-LCI – 3-Bolt","offer_id":55690309501304,"sku":"RAC-B2102SD","price":5064.0,"currency_code":"GBP","in_stock":true},{"title":"LCI – 5-Bolt","offer_id":55690309534072,"sku":"RAC-B2106SD","price":5064.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/7375\/5750\/files\/ast-5300-3-way-motorsport-coilovers-bmw-f80-m3-f82-m4-f83-m4-6977960.png?v=1792787178","url":"https:\/\/clubsportgarage.co.uk\/products\/ast-5300-3-way-motorsport-coilovers-bmw-f80-m3-f82-m4-f83-m4","provider":"Clubsport Garage","version":"1.0","type":"link"}
