The Brabus spoiler can be bought directly from smart for approximately £130.00 in primer, it then needs to be colour coded to your car.

When you are happy with the colour match, the spoiler will need bonding to the boot lid itself, there are no screws fixing the spoiler so ensure you use a quality adhesive such as Tiger Seal.

Ensure the boot lid and bottom of the spoiler is clean of any grease or polish by rubbing over them with thinners.

Apply a even amount of adhesive to the spoiler itself, be careful not to add too much as when the spoiler is pressed onto the car you don't want it squirting out from around the edges.

Press the spoiler onto the car and tape the corners down with gaffer tape until the adhesive cures.
