Every kit is extensively tested on the MK5 chassis and refined until it balances ride quality with performance — the reason 06-09 Volkswagen Golf coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.\u003c\/p\u003e\n\u003cp\u003eER Series kits run a linear twin-piston design in a mono-tube body, with compression and rebound on separate external adjusters. That lets you fine-tune chassis balance corner by corner — stiffer front for turn-in, softer rear for exit grip, whatever the session calls for. BC Racing takes pride in choosing spring rates and damper valving that balance comfort and performance — you never end up with the oversprung, harsh-riding kit some brands ship as their only option. Drivers who want to deviate from the factory setup can order Swift Springs, custom spring rates, and custom valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of customization most brands reserve for their top-tier race kits.\u003c\/p\u003e\n\u003cp\u003eBC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep customization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These 06-09 Volkswagen Golf coilovers arrive tuned for the MK5 chassis and ready to bolt in — no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts — no unit replacement required when it's time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e30-level rebound adjustment (top of damper)\u003c\/li\u003e\n\u003cli\u003e30-level compression adjustment (external reservoir)\u003c\/li\u003e\n\u003cli\u003eMono-tube damper with linear twin-piston design\u003c\/li\u003e\n\u003cli\u003eRide height adjustable independent of spring preload\u003c\/li\u003e\n\u003cli\u003eFront and rear camber plates standard on applicable kits\u003c\/li\u003e\n\u003cli\u003ePillowball upper mounts standard where camber plates do not apply\u003c\/li\u003e\n\u003cli\u003eSwift Spring and custom spring rate upgrades available at checkout\u003c\/li\u003e\n\u003cli\u003eCustom damper valving paired with custom spring rates on request\u003c\/li\u003e\n\u003cli\u003eFully rebuildable — replacement parts available from BC for the life of the shock\u003c\/li\u003e\n\u003cli\u003e2-year manufacturer warranty against defects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"table table-striped table-primary\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eH-75-ER\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Name\u003c\/td\u003e\n\u003ctd\u003eER Series Coilovers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle\u003c\/td\u003e\n\u003ctd\u003e2005-2013 Audi 06-09 Volkswagen Golf\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrivetrain\u003c\/td\u003e\n\u003ctd\u003eFWD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Code\u003c\/td\u003e\n\u003ctd\u003eMK5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDamping Adjustment\u003c\/td\u003e\n\u003ctd\u003e2-Way (30 levels rebound 30 levels compression)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRide-Height Adjustable\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Front\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Rear\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCamber Plates - Front\u003c\/td\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCamber Plates - Rear\u003c\/td\u003e\n\u003ctd\u003eNot Applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuspension Design - Front\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuspension Design - Rear\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotes\u003c\/td\u003e\n\u003ctd\u003e\u003cul\u003e\n\u003cli\u003eTrue-Rear coilover conversion replaces the factory divorced shock-and-spring with a single coilover unit.\u003c\/li\u003e\n\u003cli\u003eThe ER Series is not available in Extreme-Low configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eVehicle Fitment\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e2005 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2006 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2007 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2008 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2009 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2010 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2011 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2012 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003cli\u003e2013 Audi 06-09 Volkswagen Golf FWD (MK5)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BC Racing","offers":[{"title":"Default Title","offer_id":63498109682033,"sku":"H-75-ER","price":1935.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2534\/9336\/files\/D-17-BR-RS-TRUE-1_a5cad277-5613-469f-9c24-ea4d4b72996f.jpg?v=1777258045","url":"https:\/\/bc.springrates.com\/products\/bc-racing-er-series-coilovers-2005-2013-audi-06-09-volkswagen-golf-mk5","provider":"BC Racing - Springrates.com","version":"1.0","type":"link"}
