The dampers are rebuildable, allowing them to be serviced rather than requiring the complete suspension to be replaced when servicing becomes necessary. Rebound adjustment changes the resistance as the damper extends after compression, while the spring platforms provide ride-height adjustment. Changing the rebound setting does not change the spring rate.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfiguration differences\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eStreet\u003c\/strong\u003e kit retains the original front and rear top mounts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStreet Performance\u003c\/strong\u003e adds camber-adjustable front top mounts, providing an additional alignment adjustment at the front strut mounting. This is separate from the damping adjustment: both kits remain single-adjustable 5100 systems. The original rear top mounts are retained with the Street and Street Performance versions, and drop links are included with those versions. Because both versions keep the separate rear spring and damper layout, choosing \u003cstrong\u003eStreet Performance\u003c\/strong\u003e does not convert the rear suspension to a true coilover. The main purchasing distinction is the front mounting equipment. Final ride height and alignment should be set together, with wheel and tyre clearance checked through the suspension's working travel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eClub Racing – Front \u0026amp; Rear Top Mounts:\u003c\/strong\u003e The ACC-B1605SD configuration uses an inverted coilover arrangement with front and rear top mounts, rather than the separate rear spring and damper layout offered by Street and Street Performance. Select this configuration only where the application and mounting requirements are confirmed. Confirm exact accessory contents and installation requirements before ordering.\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 fitting non-electronic coilovers, where supported for the vehicle. A compatible KW EDC cancellation kit is a separately available hardware alternative. Neither approach retains electronic adjustment of these replacement dampers.\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":"Street – Original Top Mounts","offer_id":55690305110392,"sku":"ACU-B1603SD","price":3012.0,"currency_code":"GBP","in_stock":true},{"title":"Street Performance – Front Top Mounts","offer_id":55690305143160,"sku":"ACT-B1603SD","price":3072.0,"currency_code":"GBP","in_stock":true},{"title":"Club Racing – Front \u0026 Rear Top Mounts","offer_id":55695540027768,"sku":"ACC-B1605SD","price":3528.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/7375\/5750\/files\/ast-5100-coilovers-bmw-e82-1m-e9x-m3-9589062.png?v=1792787180","url":"https:\/\/clubsportgarage.co.uk\/products\/ast-5100-coilovers-bmw-e82-1m-e9x-m3","provider":"Clubsport Garage","version":"1.0","type":"link"}
