Fitment Note:

This billet aluminum strut brace is listed for compatible 2021+ BMW G80/G81 M3 and G82/G83 M4 applications, as well as 2023+ BMW G87 M2 applications.

Fitment should be determined using the complete combination of BMW model, chassis designation, production year, original upper engine-bay configuration, and mounting arrangement.

Before ordering, compare your vehicle's engine-bay and upper chassis mounting arrangement with the product photos. Pay particular attention to the mounting locations, brace geometry, factory components, surrounding covers, reservoirs, intake components, and available clearance.

Vehicles equipped with aftermarket intake systems, engine-bay braces, suspension components, reservoirs, covers, or other modified engine-bay components may require additional clearance and fitment verification.

The supplied product information does not provide measured chassis stiffness, handling improvement, or structural rigidity test data. Therefore, no specific percentage increase in chassis rigidity or handling performance is claimed.

Professional installation is recommended. Correct brace orientation, mounting-point alignment, fastener security, and clearance around surrounding engine-bay components should be carefully checked during installation.
