For a track-focused installation, professional four-wheel alignment and corner-weighting should also be considered once the final ride height has been established.\u003c\/p\u003e\n\n\u003cp style=\"margin: 0 0 8px;\"\u003e\u003cstrong\u003eUseful tools \/ consumables:\u003c\/strong\u003e Suitable vehicle lifting equipment and axle stands, socket and spanner set, torque wrench, penetrating fluid, anti-seize compound and the appropriate BC Racing coilover adjustment tools.

Installation involves replacement of the complete front and rear suspension assemblies together with installation and positioning of the external reservoir components. Ride height, geometry, compression and rebound damping must then be set correctly. Professional installation and setup are recommended for a suspension system of this type.\u003c\/p\u003e\n\n\u003cp style=\"margin: 0 0 8px;\"\u003e\u003cstrong\u003eWhy BC Racing?\u003c\/strong\u003e BC Racing ER Series suspension provides independently adjustable compression and rebound damping together with external reservoirs, giving considerably greater suspension tuning control than a conventional single-adjustable coilover. The combination of monotube dampers, increased oil capacity, independent ride-height adjustment and separate 30-position compression and rebound adjustment makes the ER Series particularly well suited to serious fast-road, track-day and motorsport applications.\u003c\/p\u003e\n\n\u003cp style=\"margin: 0 0 8px;\"\u003e\u003cstrong\u003eWhat’s in the box:\u003c\/strong\u003e Complete four-corner BC Racing ER Series coilover suspension kit with front and rear dampers, 10 kg\/mm front springs, 7 kg\/mm rear springs, external reservoir assemblies, applicable upper mounting components and associated adjustment and installation components supplied with the N-11-ER-ER kit.\u003c\/p\u003e\n\n\u003cp style=\"margin: 0 0 8px;\"\u003e\u003cstrong\u003eInstallation \/ setup notes:\u003c\/strong\u003e The external reservoirs must be positioned and secured correctly during installation. Ride height, spring preload, compression damping and rebound damping should be set methodically, starting from a known baseline and making controlled adjustments. Once the required ride height has been established, all suspension mounting hardware should be tightened to the appropriate specification and a full four-wheel geometry alignment carried out before final suspension tuning.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BC Racing","offers":[{"title":"Default Title","offer_id":57979867693438,"sku":"N-11-ER-ER","price":1844.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/8274\/9408\/files\/ERSeries.jpg?v=1788679919","url":"https:\/\/www.mazspec.co.uk\/products\/bc-racing-er-series-coilover-kit-mazda-mx-5-mk1-mk2-na-nb-1989-2005-n-04-er-copy","provider":"MazSpec","version":"1.0","type":"link"}
