Looking for maximum performance for your car? Our adjustable ST XTA Coilover kits are the upgrade you need. All ST XTA systems are delivered with a linear race springs system, adjustable dampers, and aluminum unibal camber adjustable top mounts. ST XTA Coilover kits deliver precise adjustment to your ride heig ht so you control the look of your car. We manufacture the adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability while the stainless steel insert provides strength and confidence! ST XTA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 16 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, performance, or something in between; ST XTA puts the finer details of the driving dynamics in your hands. The top mounts included with our ST XTA Coilover kits allow you to adjust the camber at the front axle to dial in aggressive wheel and tire fitment. They also allow you to maximize the tire's contact patch for driving in fast corners and any other driving scenario that demands maximum grip. Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs. We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing.

Height Adjustable Coilovers with Aluminum Top Mounts and Adjustable Damping
- 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.
- 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.
- ST XTA coilovers feature adjustable rebound damping which puts you in control of how comfortable or sporty your car feels.
- Galvanized steel housing for improved resistance to corrosion.
- 5 Year Limited Warranty - Unlimited Mileage

ST Suspension XTA Performance Coilover System 02-06 Mini R50 (Incl. Conv./Cooper/Cooper S) - 18220842 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.
