► 1 – Installation Guide

Tools Required:

► 1/4” Drill
► Drill Motor
► 2 – Clamps
► Philips Screw Driver
► Jack and Jack Stands (optional)

Note: This install was performed on a hoist for ease of taking photographs, however it is not required. Elevating the car and placing the car on Jack Stands may make the installation easier, but it is optional. Follow all safety procedures if you choose to place the vehicle on Jack Stands.

Installation Procedure:

1. Begin with the Driver Side Splitter. Hold Splitter up to the bottom of the Fascia. Align the inside edge of the Splitter to the inside edge of the Fascia. Place the front of the splitter up against the factory mud flap. Temporarily hold in place with a clamp.

2. Using the Splitter as a drill guide, drill the most rearward hole in to the fascia with a ¼” drill. Press in Scrivet. Hint: Using a Philips Screw Driver will make this step much easier than using your finger tips. Recheck your alignment and drill the 2 remaining holes and install Scrivets.

3. Repeat this process for the passenger side.

4. Align the sides of the splitter as shown in the picture below. Align the rear edge of the splitter to the back edge of the fascia. Use 2 clamps to hold in place.

5. Drill a hole on 1 side and install a scrivet. Check alignment, drill hole at opposite side and install scrivet. Drill remaining holes and install the scrivets.
