It replaces all four factory dampers and springs with shortened Bilstein B8 performance dampers and Eibach Pro-Kit lowering springs, so the car sits lower and feels tighter without becoming harsh on UK roads.\u003c\/p\u003e\n\u003cp\u003eBecause the dampers are shortened to suit the lower spring height, they keep enough working stroke to control the body properly, which a set of lowering springs on worn or standard dampers can't do. The kit is developed for this specific car and uses the factory spring seat design, so it bolts in without changes to the bodywork or wheel arches.\u003c\/p\u003e\n\u003ch3\u003ePerformance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRide height:\u003c\/strong\u003e Fixed lowering, typically 30-50mm depending on the car\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping:\u003c\/strong\u003e Fixed, tuned for this car\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper design:\u003c\/strong\u003e Monotube gas-pressure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRide-height figures are Bilstein's application data for this part number, measured against the car's standard ride height.

Where the car has front struts, they must be dismantled with spring compressors to swap the springs, and where the car uses a strut insert the cartridge cap nut is tightened to 130 Nm with the Bilstein cartridge tool. Check the top mounts, bearings, bump stops and dust covers while everything is apart and replace any that are worn. Let the springs settle for a few hundred miles, then have a four-wheel alignment carried out and check the headlight aim. We recommend professional fitting.\u003c\/p\u003e\n\u003ch3\u003eHow do I check this fits my BMW X3?\u003c\/h3\u003e\n\u003cp\u003eThis kit is for the BMW X3 E83 (2003-2011). Check the details in the Fitment section, and if you're unsure, send us your registration or VIN and we'll confirm before you order.\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, typically 30-50mm depending on the car; 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\u003eCan I fit this to a car with electronic or adaptive dampers?\u003c\/h3\u003e\n\u003cp\u003eThis kit uses conventional dampers. If your car has factory electronic damping, check the Fitment notes above, as Bilstein makes separate DampTronic and EVO SE kits for many of these cars.\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's the difference between the B12 Pro-Kit and B12 Sportline?\u003c\/h3\u003e\n\u003cp\u003eBoth pair Bilstein dampers with Eibach springs. The Pro-Kit gives a moderate drop for everyday comfort; the Sportline sits lower and feels firmer. Not every car has both versions available.\u003c\/p\u003e\n\u003ch3\u003eWhat type of dampers does it use?\u003c\/h3\u003e\n\u003cp\u003eMonotube 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.
