It replaces the standard dampers and springs with Bilstein DampTronic dampers and matched Eibach lowering springs, lowering the car while keeping the electronic damper control working.\u003c\/p\u003e\n\u003cp\u003eThe dampers connect to the car's existing wiring, so the factory system carries on adjusting them as you drive.

Where the car has front struts, they must be dismantled with spring compressors to swap the springs. Check the top mounts, bearings and bump stops while everything is apart and replace any that are worn. Make sure every connector is clipped in fully before the first drive, then let the springs settle and have a four-wheel alignment carried out. We recommend professional fitting.\u003c\/p\u003e\n\u003ch3\u003eWill this fit every BMW 3-Series F31?\u003c\/h3\u003e\n\u003cp\u003eNo. Bilstein makes separate kits for different versions of this car, split by body style, drivetrain, engine or axle load. This one is for the BMW 3-Series 335d 335i F31 Estate xDrive (2012-2019). Check the Fitment section and the Not suitable for line, and contact us with your registration if you're unsure.\u003c\/p\u003e\n\u003ch3\u003eHow much lower will my car sit?\u003c\/h3\u003e\n\u003cp\u003eBilstein doesn't list an exact figure for this part in our data. Across the range the drop is fixed lowering, varies by car (see Performance); contact us and we'll check the figure for your car.\u003c\/p\u003e\n\u003ch3\u003eIs the ride height adjustable?\u003c\/h3\u003e\n\u003cp\u003eNo. The B12 gives a fixed drop set by the springs. If you want to set the height yourself, look at Bilstein's B14 or B16 coilovers for your car.\u003c\/p\u003e\n\u003ch3\u003eWill my car's adaptive damping still work?\u003c\/h3\u003e\n\u003cp\u003eYes. This kit connects to the car's own electronic damper control, so the system keeps adjusting the dampers as before. It is only for cars that came with electronic damping from the factory.\u003c\/p\u003e\n\u003ch3\u003eDo I need a wheel alignment after fitting?\u003c\/h3\u003e\n\u003cp\u003eYes. Changing the ride height changes the suspension geometry, so a four-wheel alignment is needed after fitting. Let the springs settle for a few hundred miles first.\u003c\/p\u003e\n\u003ch3\u003eIs it road legal in the UK?\u003c\/h3\u003e\n\u003cp\u003eYes, this kit is designed for road use. As with any suspension modification, you should tell your insurer once it has been fitted.\u003c\/p\u003e\n\u003ch3\u003eWhat type of dampers does it use?\u003c\/h3\u003e\n\u003cp\u003eTwin-tube gas-pressure, according to Bilstein's data for this part number. Gas-pressure dampers resist fading when they get hot during hard driving.\u003c\/p\u003e\n\u003ch3\u003eIs there a warranty?\u003c\/h3\u003e\n\u003cp\u003eYes. Bilstein suspension is covered against defects in materials and workmanship. Contact us with your order number if you have any problem.\u003c\/p\u003e\n\u003ch3\u003eDo I need new top mounts?\u003c\/h3\u003e\n\u003cp\u003eThey are not included. If your existing top mounts, bearings or bump stops are worn, replace them while the suspension is apart, as worn mounts can cause knocks and affect the alignment.\u003c\/p\u003e","brand":"Bilstein","offers":[{"title":"Default Title","offer_id":58918520881535,"sku":"46-331489","price":2216.16,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6251\/6693\/files\/bilstein-b12_965f7d17-c7d3-42dd-b705-905b1ffa7637.jpg?v=1792759978","url":"https:\/\/coilovers.co.uk\/products\/bilstein-b12-damptronic-coilovers-bmw-335d-335i-f31-estate-xdrive-12-19","provider":"Coilovers.co.uk","version":"1.0","type":"link"}
