Each corner uses a high gas-pressure monotube damper, which runs cooler and stays more consistent than a twin-tube design when the car is driven hard for long periods – ideal for fast road use, track days and drifting.\u003c\/p\u003e\n\u003cp\u003eOn cars with MacPherson strut front suspension the MonoPro uses an inverted damper design for extra strength under cornering and braking loads, and a low-friction damper coating helps the suspension react to small inputs. The 16-way damping adjuster lets you go from a softer road setting to a firmer track setting in a few clicks. Ride height is set by screwing the damper body up or down, separately from spring preload, so you can lower the car without losing suspension travel or changing how the spring behaves. This version bolts to your existing front top mounts to keep road noise and vibration to a minimum; it does not add camber adjustment.\u003c\/p\u003e\n\u003cp\u003eThe latest Version 2 front lower brackets have the anti-roll bar drop link mount built in, so fitting is simpler than on earlier kits. This is the Default spring rate kit (8kg front, 10kg rear), the best choice for road cars and occasional track days. A stiffer Track Pack is listed separately.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper type:\u003c\/strong\u003e high gas-pressure monotube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping adjustment:\u003c\/strong\u003e 16-way, soft to hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring pack:\u003c\/strong\u003e Default\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront spring:\u003c\/strong\u003e 8kg\/mm (approx. 78 N\/mm), 175mm long, 65mm ID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear spring:\u003c\/strong\u003e 10kg\/mm (approx. 98 N\/mm), 200mm long, 65mm ID\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment:\u003c\/strong\u003e Height and Damping\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront top mounts:\u003c\/strong\u003e uses your existing OEM top mounts (not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHSD part number:\u003c\/strong\u003e HSD8-MP-BM17\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e16-way adjustable high gas-pressure monotube dampers for consistent performance when driven hard\u003c\/li\u003e\n\u003cli\u003eInverted damper design on strut front suspension and low-friction damper coating\u003c\/li\u003e\n\u003cli\u003eFull-length height adjustment, separate from spring preload\u003c\/li\u003e\n\u003cli\u003eUses your standard top mounts for low noise and vibration\u003c\/li\u003e\n\u003cli\u003e6061 aluminium spring seat collars\u003c\/li\u003e\n\u003cli\u003eZinc-plated damper bodies with e-coated lower mounts and full-length dust boots for corrosion protection\u003c\/li\u003e\n\u003cli\u003eVersion 2 front brackets with built-in anti-roll bar drop link mount\u003c\/li\u003e\n\u003cli\u003eRear adjuster takes 200mm coilover springs for easy spring rate changes from 6kg to 20kg\u003c\/li\u003e\n\u003cli\u003eDesigned as a bolt-on kit for this car, with spares and rebuild support through the UK distributor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's in the Kit?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4 x HSD MonoPro coilovers\u003c\/li\u003e\n\u003cli\u003eShorter front anti-roll bar drop links\u003c\/li\u003e\n\u003cli\u003e2 x C-spanners for height and preload adjustment\u003c\/li\u003e\n\u003cli\u003e1 x set of fitting instructions\u003c\/li\u003e\n\u003cli\u003e2 x HSD stickers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e the HSD feature graphics in the gallery are illustrations of the range; the coilovers supplied are specific to this car.\u003c\/p\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW 3 Series F34 Gran Turismo (2013-2020)\u003c\/li\u003e\n\u003cli\u003eAll models\u003c\/li\u003e\n\u003cli\u003eUses your existing front top mounts\u003c\/li\u003e\n\u003cli\u003eEngines\/models: 316i, 318i, 320i, 328i, 330i, 335i, 340i, 316d, 318d, 320d, 325d, 330d, 335d\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e Any model not listed above.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThe kit is a direct replacement for the standard dampers and springs on the BMW 3 Series F34 Gran Turismo, using the factory mounting points with no cutting or drilling. Your existing front top mounts are transferred to the new coilovers, so check their condition and replace them if worn. Fit the shorter anti-roll bar drop links supplied to the integrated mount on the front brackets. Set an even ride height side to side using the body adjustment rather than the preload collars, tighten every lock ring, then have a full four-wheel alignment done. Check the ride height and that all bolts and lock rings are tight again after the first few hundred miles. We recommend professional fitting by a garage with spring compressors and alignment equipment.\u003c\/p\u003e\n\u003ch3\u003eShould I choose the Default or Track Pack springs?\u003c\/h3\u003e\n\u003cp\u003eChoose Default for road use and occasional track days. The Track Pack's stiffer springs reduce body roll and suit regular track use or very low ride heights, but the ride is firmer. This listing is the Default kit.\u003c\/p\u003e\n\u003ch3\u003eDoes this kit fit my car?\u003c\/h3\u003e\n\u003cp\u003eHSD lists this kit for the BMW 3 Series F34 Gran Turismo (2013-2020). Not suitable for: any model not listed above.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between the OEM and camber top mount versions?\u003c\/h3\u003e\n\u003cp\u003eThe OEM version reuses your standard rubber top mounts for the quietest ride but has no camber adjustment. The camber top mount version adds adjustable front camber for better tyre contact on track, with slightly more noise and vibration.\u003c\/p\u003e\n\u003ch3\u003eAre MonoPro coilovers too firm for daily driving?\u003c\/h3\u003e\n\u003cp\u003eNo. With the Default springs and a softer damper setting the MonoPro rides well on the road, and you can firm up the damping for track days. The Track Pack is noticeably firmer.\u003c\/p\u003e\n\u003ch3\u003eCan I lower the car without changing the spring preload?\u003c\/h3\u003e\n\u003cp\u003eYes. HSD coilovers adjust ride height by screwing the damper body in its lower mount, separately from the spring preload collar, so you keep the same spring behaviour and damper travel.\u003c\/p\u003e\n\u003ch3\u003eDo I need a wheel alignment after fitting?\u003c\/h3\u003e\n\u003cp\u003eYes. Changing ride height alters toe and camber, so a full four-wheel alignment is needed after fitting and after any big height change.\u003c\/p\u003e\n\u003ch3\u003eAre these coilovers road legal?\u003c\/h3\u003e\n\u003cp\u003eYes, they are designed for road use. Lowering is a modification, so tell your insurer, and keep enough ground clearance and suspension travel for UK roads.\u003c\/p\u003e\n\u003ch3\u003eWhat warranty do HSD coilovers have?\u003c\/h3\u003e\n\u003cp\u003eHSD coilovers are covered by a 12-month warranty against defects in materials and workmanship. Spare parts, springs and rebuild support are available through the UK distributor.\u003c\/p\u003e","brand":"HSD","offers":[{"title":"Default Title","offer_id":58919667892607,"sku":"HSD-K-BMW-3-SERIES-F34-GT-M-D","price":854.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6251\/6693\/files\/hs8-mp-bm17_1_29_53104713-d2f8-4744-9023-f7974e27a6f9.jpg?v=1792766822","url":"https:\/\/coilovers.co.uk\/products\/hsd-monopro-coilovers-bmw-3-series-f34-gran-turismo-oem-top-mount-13-20","provider":"Coilovers.co.uk","version":"1.0","type":"link"}
