AST ASTLS-22-294 Lowering Springs for 22-24 BMW G42 2 Series M240i xDrive Coupe

Vehicle Fitment

• 2022-2024 BMW M240i xDrive Coupe (G42, B58 3.0L TwinPower Turbo I6 369-382hp depending on market, xDrive AWD, 8-speed Steptronic automatic)

Fitment Notes

• This kit is specifically engineered for the G42 M240i in xDrive (all-wheel drive) configuration. The M240i xDrive was the only drivetrain available at launch and remains the primary variant in most markets. A rear-wheel-drive M240i entered production in Summer 2022 for the 2023 model year in select markets - the RWD M240i requires a separate, different AST spring application. Confirm your drivetrain before ordering.
• The G42 2 Series Coupe is available in one body style only - there is no G42 Convertible or Gran Coupe. This part number covers the two-door Coupe body across all trim levels equipped with the M240i xDrive drivetrain.
• The M240i xDrive features a significantly wider front track (+63mm) and rear track (+35mm) compared to the standard G42 220i/230i models. This wider-track xDrive platform requires its own dedicated spring calibration - separate from any RWD G42 application.
• The asymmetric 30mm front / 25mm rear drop reflects the additional front-end weight of the M240i's xDrive front axle and B58 engine, correcting for the slightly nose-heavy weight distribution that AWD adds to the platform. This calibration produces a level, balanced lowered stance.
• G42 M240i xDrive models optionally equipped with Adaptive M Suspension (electronically controlled variable dampers): EDC compatibility for this fixed spring kit has not been explicitly confirmed in available AST documentation. If your M240i xDrive has factory Adaptive M Suspension, confirm EDC compatibility directly with AST before ordering. A separate AST Adjustable Lowering Spring kit (ASTALS-21-003) covers the G42 M240i xDrive with confirmed EDC compatibility.
• The M240i xDrive is equipped with an M Sports differential (fully variable electronically controlled) as standard. This spring kit does not interact with or affect the differential's operation.
• For cars with standard M Sport suspension (as fitted to most M240i variants): the indicated 30mm front / 25mm rear drop is measured from the factory M Sport ride height. As delivered, the M240i already has an M Sport suspension tune - vehicles with any additional factory lowering option will see a modestly reduced effective drop.
• Front drop: 30mm / Rear drop: 25mm. These are fixed values - this is not an adjustable spring kit.
• Wheel alignment must be verified and corrected following installation. ABS sensor positions should be re-adjusted post-installation.

Features

• G42 M240i xDrive-specific progressive spring rate, developed and validated by AST engineers for the M240i's wider-track xDrive platform on the CLAR architecture - a distinct calibration from both the RWD M240i and the G22 M440i xDrive applications, reflecting the G42's specific weight distribution, front track geometry, and M Sports differential interaction.
• Asymmetric 30mm front / 25mm rear drop - the greater front drop corrects for the xDrive front axle's additional mass and the B58 engine's front-heavy contribution, delivering a level, balanced lowered stance without a tail-high or nose-down appearance.
• Lowers the M240i's center of gravity meaningfully at both axles, reducing body roll, sharpening corner-entry response, and enhancing the chassis composure of a platform that is already rear-biased and dynamically engaging from the factory.
• Progressive spring design improves body motion control at spirited pace while retaining sufficient compliance for everyday use - the M240i's intended dual personality as a daily-driver sports coupe and spirited canyon or track-day tool.
• Direct OEM spring replacement - installs into the factory front MacPherson strut housings and rear multi-link spring perches using original mounting hardware; no modification to the xDrive system, M Sports differential, or suspension geometry required.
• Developed and tested to work correctly with the factory shock absorbers and struts, allowing a spring-only installation without requiring 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 30mm/25mm 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-22-294 Lowering Spring Kit is engineered for the second-generation BMW 2 Series Coupe M240i in xDrive all-wheel drive specification (G42), covering 2022-onward production. The G42 M240i xDrive sits on BMW's CLAR rear-wheel-drive platform - the same architecture underpinning the G20 3 Series and G22 4 Series - making it a genuinely rear-biased AWD platform that handles very differently from the front-heavy FWD-based 2 Series Gran Coupe. The xDrive version of the M240i has a meaningfully wider front and rear track than the standard G42 220i/230i models (63mm wider at the front, 35mm wider at the rear), which is one of the reasons this kit carries a separate part number from any RWD M240i spring application. These wider-track dimensions change the front and rear spring perch geometry and weight distribution enough to warrant a dedicated calibration.

The 30mm front and 25mm rear asymmetric drop addresses this directly. The greater drop at the front corrects for the xDrive front axle's additional mass and the B58 engine's forward weight contribution, ensuring the car sits level rather than tail-down after installation. At these values the G42's MacPherson strut front and multi-link rear geometry remain within the range where standard alignment correction efficiently restores all four corners to optimal settings. The practical improvements on an already-engaging platform are real: less body roll under cornering, a more committed initial steering response, and a stance that better reflects the dynamic character the M240i delivers on the road.

Owners with factory Adaptive M Suspension (variable electronically-controlled dampers) who want confirmed EDC compatibility should consider the AST Adjustable Lowering Spring kit (ASTALS-21-003) for the G42 M240i xDrive. For standard suspension M240i xDrive configurations, the ASTLS-22-294 provides a proven, direct-replacement fixed-drop solution. 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.
