Vehicle Fitment

• 2021+ BMW M2 (G87)

• 2021+ BMW M3 Touring (G81)
• 2021+ BMW M4 Coupe (G82)
• 2021+ BMW M4 Convertible (G83)

Fitment Notes

• This kit addresses a known interference issue specific to the G8X platform - the factory fender liner's plastic air-directing vents (part of the front-mounted heat exchanger ducting) contact the tire during full-lock steering turns after the vehicle has been lowered, fitted with wider wheels, wider tires, or wheel spacers.
• Suitable for any G8X M2/M3/M4 owner running a lowered suspension setup, aftermarket wheels with greater width or offset, or wheel spacers that reduce tire-to-liner clearance.
• Also beneficial for vehicles running stock suspension if larger-diameter or wider tires are installed.
• Bolt-on installation using factory liner mounting points - no drilling or cutting required.

Features

• Eliminates tire-to-fender-liner rubbing during steering lock in modified G8X M2/M3/M4 applications - a direct solution to one of the most commonly reported fitment issues on the G8X platform when lowering or widening the wheel/tire package.
• Designed by AST/MOTON to maintain critical airflow to the front-mounted heat exchangers - unlike trimming or removing the OEM vent, this kit preserves the factory cooling architecture.
• Black anodized metal construction - significantly more durable than the OEM plastic vent it replaces, with a clean, purposeful appearance inside the wheel arch.
• All necessary mounting hardware is included - the kit bolts directly to the existing fender liner attachment points for a straightforward installation.
• Sold as a complete set of 2 pieces covering both the driver and passenger side front wheel arches.
• Engineered by AST/MOTON, a motorsport-pedigreed suspension and chassis components manufacturer with extensive experience developing solutions for high-performance BMW platforms.

Product Description

The AST 89GK-G8X-A1-266S Front Wheel Arch Clearance Kit solves one of the most common issues G8X M2/M3/M4 owners encounter after modifying their suspension or wheel/tire setup: the factory plastic air-duct vents in the front fender liner making contact with the tire at full steering lock. Rather than trimming away the OEM vent - which can compromise cooling to the front heat exchangers - AST/MOTON engineered this purpose-built replacement that provides the additional clearance needed while keeping the factory airflow path intact.

The two black anodized metal plates bolt directly to the existing fender liner mounting points on both sides of the front axle, requiring no drilling, cutting, or permanent modification. The anodized metal construction is a significant durability upgrade over the OEM plastic, and the clean matte black finish blends naturally within the wheel arch. Whether you're running coilovers, an AST cup kit, lowering springs, wheel spacers, or a wider wheel-and-tire combination, this kit is a clean, affordable, and purpose-engineered fix for the G8X platform.
