Installing  rear car spoilers:

1Measure the length and width of the trunk lid. Take into consideration the brace structure on the underside of the lid to help you determine where to install the spoiler.

2

Purchase the rear spoiler. Be sure to get one that will fit your car. Take your measurements with you to make sure the spoiler does actually fit where you intend to install it.

3

Put the rear spoiler wing brackets together. Carefully tighten all the bolts that hold the rear spoiler to the brackets.

When measuring where to mount your new rear spoiler, you will need to find the center of the rear spoiler and the center of the rear deck lid(trunk lid). Then line up the two center points and the measure out to where you will drill your mounting holes.

4

Mark the holes on the outside of the trunk where you intend to install the rear spoiler, I suggest using masking tape to mark where to drill your holes. Make sure you have the rear spoiler pointing in the right direction.

5

Drill holes through the top sheet metal of the trunk and the metal underside. Start with a smaller hole than necessary. Progressive drill larger holes until you have a large enough hole for the bolts to pass through. Vacuum the scraps from the trunk when you finish this step.

6

Smooth the insides of the holes with a hand tool equipped with a small sander. Paint the inside of the holes with touch-up paint to keep rust from forming.

7

Attach the rear spoiler to the trunk with the help of a friend. Be sure to put the washers in place before your tighten the bolts. The spoiler should not be loose. Make sure all the bolts have equal pressure on them.
