The XTA plus 3 coilover kit gives your car maximum performance for the road and the tools you need for any challenge. From the factory, the XTA plus 3 coilover kit is equipped with KW dampers that are adjustable in high-speed and low- speed compression as well as adjustable rebound damping. With 24 clicks of adjustment for each, high-speed and low-speed compression damping and 18 clicks of rebound adjustment, your suspension knows no limits. It doesn't matter if you bolt in an aftermarket roll cage, weld in a cage, upgrade to spherical bushing or changed wheel loads - the XTA plus 3 coilover has what it takes to keep your car dialed! Of course, the XTA plus 3 also includes a parts approval certificate, race springs and aluminium unibal top mounts. Easy lowering adjustment: Like all ST coilovers the ride height adjustment is made via seamless thread on the galvanized strut housing. This even allows the ride height to be adjusted even when the kit is installed by adjustubg the spring perch higher or lower! NOTE: The lowering of each vehicle differs greatly with ST XTA plus 3 coilovers due to the type of construction. KW Engineering: Exclusive for ST suspension. The high-quality ST XTA plus 3 coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a mono block guide and seal package reduces the friction of the damper as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions.
The most versatile ST coilover kit ever built. Seamless ride height adjustability, aluminum unibal top mounts, 24 clicks of low-speed and high-speed compression adjustability, 18 clicks of rebound adjustability put you in absolute control!
ST XTA PLUS 3 COILOVER KIT (ADJUSTABLE DAMPING WITH TOP MOUNTS) - 1820220842
Height and 3 Way Damping Adjustable Coilovers with Aluminum Top Mounts
- Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
- Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
- ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it's making the proper forces before being put into the ST box.
- Seamless Ride Height Adjustment - ST's composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look.
- From the factory, the XTA plus 3 coilover kit is equipped with KW dampers that are adjustable in high- and lowspeed compression as well as adjustable rebound damping.
- Linear race spring system provides a consistent response while driving and makes it easy to swap rates to further personalize your setup.
- Aluminum unibal top mounts improve steering response and feedback while allowing you to dial in your camber when applicable.
- Galvanized steel housing for improved resistance to corrosion.
- 5 Year Limited Warranty - Unlimited Mileage

ST XTA Plus 3 Coilover Kit Mini Cooper R50/R53 (incl. Conv./Cooper/Cooper S) - 1820220842 FAQ
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.
Ride height is set on the threaded body or the lower mount, and the damping (how firm the shock feels) with the adjuster when the kit has one. Some kits also let you set spring preload and camber at the top mount. The Part details above list what this exact kit adjusts.
Yes. Changing ride height changes camber and toe, so have the car aligned once the height is set and the suspension has settled after a short drive.
Set all four corners before the alignment, keep the drop inside the maker's range, and re-check the height after the first drive because the springs settle. Going lower than the maker recommends costs ride quality and tire life.
The car settles a little over the first few drives. After that, re-check the ride height, the lock rings on the collars and the top-mount hardware, then get the alignment done.
Yes. Most coilovers are built for daily use when set to the maker's recommended height and a softer damping setting. Track-focused series ride firmer.
Yes — monthly options show right under the Add to Cart button. Affirm, Klarna, PayPal Pay Later and Snap Finance are offered at checkout, and checking what you qualify for does not affect your credit score.
Install and care: coilovers
Before you start
- Read the maker's guide and note the recommended ride-height range for your car.
- Book an alignment for after the install; the car needs one.
Do
- Set all four corners to the same drop before the alignment and re-check the height after the first drive.
- Keep the threads clean and lightly lubricated so the collars still turn next season.
Don't
- Don't go lower than the maker's range; it costs ride quality and tire life.
- Don't skip the alignment.
