The ER Series coilovers bring with them the high quality and unique features seen on the BR and RM type but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates.\u003c\/p\u003e\n\u003ch3\u003eEXTERNAL RESERVOIR\u003c\/h3\u003e\n\u003cp\u003eThe external reservoir ER Series coilovers allow BC Racing to increase the oil capacity of the damper unit. The additional oil capacity reduces peak oil temperatures which decreases variations in damping rates due to oil viscosity changes. The reduction in damping rate variations improves handling and ultimate on road and track performance.\u003c\/p\u003e\n\u003ch3\u003eSEPARATE COMPRESSION AND REBOUND DAMPING ADJUSTMENT\u003c\/h3\u003e\n\u003cp\u003eBy separating the adjustment for damping compression and rebound the ER Series allows you to dial the vehicle in to your exact needs. When braking hard whilst approaching a corner you want the car to transfer weight to the front tyres to maximise grip for the braking effort and also to allow you to trail brake into the corner without the car understeering.\u003c\/p\u003e\n\u003cp\u003eAs you start to lift off the brakes on corner entry you don’t want the suspension to snap back up too quickly as this will remove the loading from the front tires too quickly and lead to understeer. As soon as the car starts to understeer you need to wind off the steering lock to reduce the work effort applied to the tires to allow them to regain traction. This slows the vehicles ultimate speed.\u003c\/p\u003e\n\u003cp\u003eThe compression damping adjustment allows you to fine tune the way the car rolls onto its front tires during braking and the separate rebound adjustment allows you to fine tune the way the car responds as you come off the brakes to enter the corner proper and keep the front end hooked up. This allows you to get back on the power sooner and maximize corner exit speed. Corner exit speed is vital because this determines you maximum speed achieved down the next straight.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eCustom spring rates are available. You can request custom spring rates by entering the rates you want in the special instructions box after clicking add to cart. Spring rates up to 18K are available in BC Springs. Rates higher than 18K will require Swift spring upgrade.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003e\u003cstrong\u003e\u003cu\u003ePLEASE NOTE:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eSUPER LOW KIT, CUSTOM SPRING RATES, OR SWIFT SPRINGS ARE BUILT TO ORDER (\u003cstrong\u003e4-6 WEEK BUILD TIME\u003c\/strong\u003e)\u003c\/p\u003e","brand":"BC Racing","offers":[{"title":"Default Title","offer_id":46731764957371,"sku":"BC Racing Coilovers-I-02-ER","price":2675.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/9556\/2683\/products\/image_228ee3f5-171c-45df-ac88-34fe3b3ca04b.jpg?v=1751245975","url":"https:\/\/drifthq.com\/en-ca\/products\/bc-racing-coilovers-er-series-coilover-for-99-05-bmw-3-series-sedan-i-02-er","provider":"Drift HQ","version":"1.0","type":"link"}
