ST Suspensions XTA Coilover Kit for MINI R50, R52 and R53

The ST Suspensions XTA 18220842 coilover kit combines adjustable ride height, externally adjustable rebound damping and aluminium uniball front top mounts for a more configurable first-generation MINI suspension setup. Tune the stance and damping to suit your driving priorities rather than relying on a fixed lowering spring and damper combination. Ships fast across Canada and the US.

Adjustment and Design

• Listed lowering range: 20–50 mm front and rear, approximately 0.8–2.0 inches.
• Externally adjustable rebound damping using KW damper technology.
• Aluminium uniball top mounts with front camber adjustment.
• Race spring system with adjustable spring perches.
• Galvanized steel strut housings with additional corrosion protection.
• Twin-tube damper design with dust protection.

Vehicle Fitment

• MINI Cooper R50 hatchback, listed North American application: 2002–2006.
• MINI Cooper S R53 hatchback, listed North American application: 2002–2006.
• MINI R52 convertible, including Cooper and Cooper S applications; confirm exact year and vehicle details before ordering.

The R52 convertible is a separate chassis, not an R50 convertible. Do not assume fitment for later R56 hatchbacks or R57 convertibles based on the Cooper name alone. Build date, axle-load limits and the current application documentation must match the vehicle.

Installation and Setup

Follow the supplied installation and damper-setup instructions and remain within the approved adjustment range. Check wheel-to-strut clearance, tyre-to-body clearance, suspension travel and brake-hose routing throughout steering and suspension movement. Original wheels and tyres may require spacers; assess compatibility rather than assuming an aggressive wheel fitment will clear.

Have the vehicle aligned after installation and after significant ride-height or camber changes. Actual lowering varies with vehicle specification and starting ride height. Inspect and maintain the threaded adjusters, especially after winter road-salt exposure; galvanized housings are not stainless steel. This is the XTA kit, not the separately specified XTA Plus 3 system.
