Dinan also converts the rear from the stock progressive-rate springs to a more predictable linear-rate design, reducing body roll without compromising compliance. The system allows up to 2\" of drop in front and 2-1\/8\" in the rear, though Dinan recommends 1\" front and 1-1\/8\" rear to maintain the civilized ride quality the M5 is built for.\u003c\/p\u003e\u003cp\u003eThreaded collars allow precise ride height adjustment front and rear. Suspension packers are included to fine-tune bump stop clearance for your preferred balance of handling and comfort. Components are machined from 6061-T6 aluminum and black anodized.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDinan F90 M5 Adjustable Coilover System Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e+\u003c\/strong\u003e Retains factory electronic shocks — Dinan replaces springs only\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Spring rates 20% stiffer front, 15% stiffer rear\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Rear converted from progressive to linear rate for improved predictability\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Up to 2\" drop front, 2-1\/8\" rear (Dinan recommended: 1\" front, 1-1\/8\" rear)\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Threaded collars for precise front and rear ride height adjustment\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Progressive bump stops and suspension packers included\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Helper springs maintain proper operation under droop conditions\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Components machined from 6061-T6 aluminum, black anodized\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Stock upper spring mounts retained for quiet operation\u003cbr\u003e\u003cstrong\u003e+\u003c\/strong\u003e Substantial reduction in body roll\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":51268686872822,"sku":"DNND190-0901","price":1599.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/fb537dac4b094f9e776b6d40644be0d3L.jpg?v=1784135423","url":"https:\/\/autotecknic.com\/products\/dinan-adjustable-coilover-suspension-system-bmw-f90-m5","provider":"AutoTecknic USA","version":"1.0","type":"link"}
