Step 1  Remove pins on bottom of trunk using a flathead screwdriver and set the carpet to the side 

Step 2  

Tape the included plastic templates to the bottom of spoiler so they remain in place and don't fall out

Place the spoiler on the trunk in the position you will be mounting it, then tape down the templates directly to the trunk 

Step 4  

Remove the spoiler and add additional tape to support templates in order to avoid any movement 

Step 5  

Use your center punch to poke an initial mark on each of the 6 templates openings to indicate where the holes will be drilled 

Step 6  

Drill 1/8” inch pilot holes on all 6 punches that you made with the center punch 

Step 7  

Drill 9/32” inch holes to expand the size of original 1/8” holes you just drilled 

Step 8  

Drill 1/8” inch hole through the entire trunk on the innermost hole on both sides to puncture through to the bottom side 

Step 9  

Drill a 5/8 hole on the bottom side of the trunk where your pilot hole is showing through 

Step 10

Apply gaskets over each hole on the top of the trunk 

Step 11  

Apply foam tape to the edges of the bottom of the spoiler and use scissors to cut as needed around the edges 

Step 12  

Set spoiler on trunk and get one of your 10mm bolts started on each side and tighten hand tight to ensure proper alignment  

Step 13

Get the rest of the 10 mm bolts into place and tighten them down all the way (You will need to use your extension to get the third bolt on)
