Separate low-speed and high-speed compression controls are located on the reservoirs, with an independent rebound adjustment. The compression ranges refer to damper velocity rather than road speed, giving separate control over different suspension inputs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMounting, supplied equipment \u0026amp; reservoirs:\u003c\/strong\u003e Springs and camber-adjustable front top mounts are included, with rear mounting provision following the application-specific kit specification. Front camber adjustment acts on alignment and is separate from the three damper controls. Ride height is set through the spring platforms; changing a damping setting does not change the spring rate. \u003cstrong\u003eDrop links are included\u003c\/strong\u003e with both drivetrain versions. RAC-B2022SD is the rear-wheel-drive kit and RAC-B2024SD is the xDrive kit for the applications listed. The external reservoirs require secure mounting and hose routing that remains clear throughout steering and suspension travel. \u003cstrong\u003eReservoir mounting brackets are optional accessories\u003c\/strong\u003e rather than standard kit contents.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation \u0026amp; setup:\u003c\/strong\u003e For factory Electronic Damper Control applications, Clubsport Garage recommends coding out EDC when fitting non-electronic coilovers, where supported. A compatible KW EDC cancellation kit provides a separately available hardware alternative. The replacement dampers remain manually controlled. Final installation should include ride-height and alignment setup and checks for wheel, tyre and hose clearance at the selected height.\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":"Rear-Wheel Drive","offer_id":55690309566840,"sku":"RAC-B2022SD","price":5160.0,"currency_code":"GBP","in_stock":true},{"title":"xDrive","offer_id":55690309599608,"sku":"RAC-B2024SD","price":5160.0,"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-g20g21-m340i-g22-m440i-g42-m240i-4122535.png?v=1792787172","url":"https:\/\/clubsportgarage.co.uk\/products\/ast-5300-3-way-motorsport-coilovers-bmw-g20-g21-m340i-g22-m440i-g42-m240i","provider":"Clubsport Garage","version":"1.0","type":"link"}
