AST ASTLS-23-081 Lowering Springs for 2017-2024 Mini Countryman John Cooper Work

Vehicle Fitment

• 2017-2020 MINI Countryman John Cooper Works ALL4 (F60, B48 2.0L TwinPower Turbo I4 231 PS / 228 hp, ALL4 AWD, 6-speed manual or 8-speed Steptronic automatic)
• 2019-2024 MINI Countryman John Cooper Works ALL4 (F60 / F60 LCI, B48 2.0L TwinPower Turbo I4 306 PS / 302 hp, ALL4 AWD, 8-speed Steptronic automatic) - uprated JCW tune introduced from summer 2019, standard on 2021 LCI facelift onward

Fitment Notes

• This kit covers the second-generation Mini Countryman JCW (F60) in full production from 2017 through to the 2024 model year - the final year of the F60 generation before the third-generation U25 Countryman replaced it. The U25 Countryman (from late 2023/early 2024) is a different platform and is not covered by this application.
• The F60 Countryman JCW is exclusively available with ALL4 all-wheel drive in all markets globally - there is no FWD variant of the JCW Countryman. This kit is therefore a universal fit for all F60 JCW Countryman models worldwide, regardless of market or year.
• Two distinct power outputs exist within the F60 JCW production run: the original 231 PS specification (2017-2019/2020) and the uprated 306 PS specification introduced from summer 2019 in select markets and standardised across the 2020 LCI facelift. Both use the same B48 2.0L TwinPower Turbo I4 engine family and share the same UKL2 platform suspension architecture - this spring kit is confirmed to cover both power outputs.
• The asymmetric 25mm front / 30mm rear drop is a deliberate calibration for the F60 JCW's transverse front-engine, FWD-derived UKL2 platform with ALL4 rear drive unit. The front-heavy weight distribution of this layout requires a more conservative front spring rate change than the rear, producing a level, balanced lowered stance rather than a nose-down or tail-low appearance.
• The F60 Countryman Cooper S (FWD and ALL4) and Cooper S E ALL4 plug-in hybrid are separate models on the same UKL2 platform but use different spring rates and are separate AST applications. This kit is confirmed for the JCW only.
• Front drop: 25mm / Rear drop: 30mm. These are fixed values - this is not an adjustable spring kit.
• ABS sensor re-adjustment is required following installation. Full four-wheel alignment must be verified and corrected after fitting.

Features

• F60 JCW-specific progressive spring rate, developed and calibrated by AST engineers for the JCW Countryman's UKL2 platform with ALL4 all-wheel drive - accounting for the B48 engine's transverse front-mounted mass, the ALL4 rear drive unit's additional rear axle weight, and the Countryman's SUV ride height and spring perch geometry.
• Asymmetric 25mm front / 30mm rear drop - calibrated to the F60 JCW's front-biased weight distribution and elevated factory ride height, delivering a level stance improvement rather than an uneven drop that would compromise suspension geometry or alignment correction range.
• Meaningfully lowers the Countryman JCW's elevated SUV center of gravity, reducing body roll in corners, improving front-end response, and sharpening the dynamic character of the ALL4 system's torque distribution in spirited driving - chassis improvements that are particularly effective on a taller SUV body where CoG reduction has a proportionally greater effect than on a lower coupe or sedan.
• Progressive spring design improves body motion control at speed while preserving the ride compliance appropriate to the Countryman's crossover character - balancing the JCW's sporting intent with the everyday practicality that distinguishes it from a pure sports car.
• Direct OEM spring replacement - installs into the factory MacPherson strut front housings and multi-link rear spring perches using original mounting hardware; no modification to the ALL4 system, rear drive unit, JCW suspension geometry, or factory electronics required.
• Developed and tested to work correctly with the factory OEM shock absorbers and struts, allowing spring-only installation without concurrent damper replacement.
• Manufactured from premium high-tensile chromium-silicon wire, individually handpicked by AST engineers for material quality and long-term fatigue resistance.
• Cold-wound on precision Wafios coiling machines, then heat-treated to increase hardness and eliminate residual winding stress from the manufacturing process.
• Each spring is individually shot peened, phosphate treated, and powder coated for maximum corrosion resistance and long-term service life.
• Each spring is blocked and computer-tested prior to shipment to minimise post-installation settling, so the 25mm/30mm target drop is achieved immediately upon installation.
• Most AST spring applications are TUV certified - certificates available upon request for technical inspection or registration compliance.
• Lifetime warranty against breakage - backed by AST Suspension's manufacturer guarantee.

Product Description

The AST ASTLS-23-081 Lowering Spring Kit is purpose-built for the second-generation MINI Countryman John Cooper Works ALL4 (F60), covering the full production run from the 2017 model year through the 2024 model year final year of the F60 generation. The F60 JCW Countryman occupies a unique position in the MINI lineup: it delivers genuine JCW performance credentials - up to 306 PS and 450 Nm in the updated specification - from an ALL4 all-wheel drive SUV body that rides notably higher than any MINI hardtop or Clubman. That elevated factory ride height makes lowering springs a particularly high-impact modification on this platform. Reducing the center of gravity of a taller SUV body yields proportionally greater reductions in body roll and improvements in cornering composure than the same drop would on a lower-slung car.

The asymmetric 25mm front and 30mm rear drop is engineered specifically for the UKL2 platform's front-biased weight distribution. The F60 is built on a transverse front-engine architecture where the B48 engine and transmission sit entirely ahead of the front axle, creating a front-heavy layout that requires a more conservative spring rate change at the front than the rear. The larger rear drop brings the rear ride height down to match, delivering a level, balanced stance rather than the nose-low or tail-high appearance that a symmetric drop would produce on this weight distribution. This calibration retains proper suspension geometry and keeps alignment correction comfortably within the range of standard four-wheel setup.

The kit covers both the 231 PS original JCW specification and the uprated 306 PS version introduced from 2019 - both share the same UKL2 suspension architecture and spring geometry, making a single kit application appropriate for the entire F60 JCW production run. Owners of the third-generation U25 Countryman JCW (production from late 2023, sold from 2024) should note that the U25 is a different platform and requires its own application. Every spring is manufactured from premium chromium-silicon wire on Wafios coiling machines in the Netherlands, individually computer-load tested before shipment, and backed by AST's lifetime warranty against breakage. TUV certification documentation is available on request.
