Fitment guarantee and VIN verification

Each bracket undergoes a geometry check to ensure there is no warping and that the mounting points for bodywork attachment are correct.

Fitment note: The left bracket (4K8821131B / 4K8821157B) works with the right-side bracket (4K8821132B / 4K8821158B). Before purchase, we recommend comparing the OE number stamped on the old part or verifying fitment using the vehicle's VIN.
