installation.

• Inspect the contents of this kit against the parts list to ensure that all components

modified with different size studs or lug patterns may require modifications to the
new hat that must be performed by a qualified machinist.

Raise the front wheels off the ground and support the front suspension
according to the vehicle manufacturer’s instructions.

Remove the front wheels, calipers and rotors.

the installation of the new brake components.
