The spring sets are model-specific, and the selector combines the vehicle application with the stated front and rear lowering so that a spring specification intended for one body style is not treated as interchangeable with another.\u003c\/p\u003e\u003cp\u003eFor the F80 M3, ASTLS-21-025 gives a stated 25mm front and 10mm rear reduction, ASTLS-22-110 gives 30mm front and 10mm rear, and ASTLS-19-008 gives 30mm front and 20mm rear. The F82 M4 set, ASTLS-17-028, gives 25mm front and 20mm rear. ASTLS-19-009 is the F83 M4 convertible set, with a stated 30mm front and 30mm rear reduction.\u003c\/p\u003e\u003cp\u003eAST develops its lowering springs for original-equipment dampers, using cold-coiled construction and a progressive spring design. These kits replace the springs rather than supplying replacement dampers or new damping controls. The lowering figures describe each matched front\/rear spring set, not independent choices for the two axles.\u003c\/p\u003e\u003cp\u003eFixed lowering springs do not provide the threaded ride-height adjustment of an adjustable spring kit. The final installed height depends on the original vehicle specification and condition, so the largest quoted reduction should not be treated as automatically the most suitable setup.\u003c\/p\u003e\u003cp\u003eWith compatible original electronically controlled dampers retained, the spring installation retains that damper system; EDC cancellation is not a routine add-on for this product. Check the exact model, body style and original suspension specification before ordering. Installation should include an alignment check and clearance checks for the actual wheel and tyre combination at the new ride 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":"F80 M3 – 25\/10mm","offer_id":55690311467384,"sku":"ASTLS-21-025","price":250.06,"currency_code":"GBP","in_stock":true},{"title":"F80 M3 – 30\/10mm","offer_id":55690311500152,"sku":"ASTLS-22-110","price":254.49,"currency_code":"GBP","in_stock":true},{"title":"F80 M3 – 30\/20mm","offer_id":55690311532920,"sku":"ASTLS-19-008","price":234.04,"currency_code":"GBP","in_stock":true},{"title":"F82 M4 – 25\/20mm","offer_id":55690311565688,"sku":"ASTLS-17-028","price":229.61,"currency_code":"GBP","in_stock":true},{"title":"F83 M4 – 30\/30mm","offer_id":55690311598456,"sku":"ASTLS-19-009","price":262.4,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/7375\/5750\/files\/ast-lowering-springs-bmw-f80-m3-f82-m4-f83-m4-3207361.png?v=1792787172","url":"https:\/\/clubsportgarage.co.uk\/products\/ast-lowering-springs-bmw-f80-m3-f82-m4-f83-m4","provider":"Clubsport Garage","version":"1.0","type":"link"}
