STOP! READ IMPORTANT SAFETY CAUTIONS AND WARNINGS BEFORE PROCEEDING. IMPORTANT SAFETY NOTICE Appropriate disassembly, assembly methods and procedures are essential to ensure the personal safety of the individual performing the kit installation. Improper installation due to the failure to correctly follow these instructions could cause personal injury or death. Read each step of the installation manual carefully before starting the actual installation.
1) Always wear safety glasses for eye protection.
2) Place ignition switch in the OFF position.
3) Always apply the parking brake when working on a vehicle.
4) Block the front and rear tire surface to prevent unexpected vehicle movement.
5) If working without a lift, always consult vehicle manual for correct lifting specifications.
6) Operate the engine only in well-ventilated areas to avoid exposure to carbon monoxide.
7) Do not smoke or use flammable items near or around the fuel system.
8) Use chemicals and cleaners in well-ventilated areas.
9) Batteries produce explosive gases, which can cause personal injury. Therefore, do not allow flames, sparks or flammable substances to come near the battery.
10) Keeps hands and any other objects away from the radiator fan blades.

1) Wipe each part with plastic prep (Dupont® 2319 or equivalent)
2) Wipe entire part with tack cloth
3) Apply adhesion promoter (Dupont® 2330S or equivalent) prior to color and clear coat applications. This part is made of TPO (Thermoplastic Polyolefin) and requires a promoter for paint adhesion.
1) Wear eye protection
2) Clean Rear fascia and quarter panel thoroughly before using drill template.
3) Lift vehicle up for removal of rear wheels
4) Secure vehicle on jack stands
5) Remove the rear wheels
Remove Fascia Attachments
1) Remove pushpins underneath the fascia, 3 total (Refer to Figure A).
2) Remove the trim from the inside of the trunk, by removing 4 pushpins and 2 plastic fasteners (Refer to Figures B & C).
3) With the trunk trim removed, loosen the nuts that secure the rear fascia to the vehicle until they are near the ends of the studs, 4 total (Refer to Figure D).
4) Remove screws in the rear wheel well that hold the fascia to the body, 2 each side (Refer to Figure E). Keep the screws; they will need to be replaced when the valance is reinstalled.
Drill Fastener Holes in Rear Fascia
1) Rear Valance Center, Lower Holes
a. Tape Drill Template #R03030089 to rear fascia (Refer to Figure L).
b. Pre drill holes (3) with 1/8” drill bit, and then drill holes (3) using 5/16” drill bit.
c. Remove drill template from rear fascia.
Prepare Rear Valance
1) Rear Valance Center (Refer to Figure F for the following steps):
a. Install supplied u-nuts to center valance, 4 total.
b. Apply adhesion promoter to the areas where double-sided tape will be used.
c. Install supplied tape strips to center valance.
2) Rear Valance Side LH/RH (Refer to Figure G, next page, for the following steps):
a. Install supplied u-nuts to side valance, 3 per side.
b. Apply adhesion promoter to the areas were double-sided tape will be used.
c. Install supplied tape strips to side valance.
d. Repeat procedure for other side valance.
3) Mark Faster Hole Center Line on Valance Components
a. Using a grease pencil mark the center of the fastener locations on the top outside edge of the valance components: Rear Valance Side LH/RH and Center (Refer to Figure H)
Modify Rear Fascia
1) Install Center Valance to rear fascia. The top of the valence should fit flush with the body lines of the rear fascia/license plate indent. (Do not remove red tape covering at this time).
a. Use masking tape to fixture center valance to the vehicle (Refer to Figure I)
2) Install side valances (Do not remove red tape covering at this time).
a. Hold Side Valences onto vehicle
b. Check fit of parts: verify consistent gaps to body and center valence.
c. Align holes of Side Valances to the 2 screws in the wheel well (2 per side).
d. Use masking tape to hold the side valences in place. Trace the outline of the Center, LH, and RH Side Valence onto the rear fascia with a grease pencil.
e. Transfer the fastener center line marks from the Center, LH, and RH Side Valence onto the rear fascia with a grease pencil. (Refer to Figure J).
f. Measure 22 mm down from trace outline where fastener center line marks are identified (Refer to Figure K). This is the drill location for the valence fastener holes.
g. Pre drill mounting holes with 1/8” drill bit, and then drill holes using 5/16” drill bit.
3) Rear Valance Cutout
a. Trace cutout lines for exhaust tips from RH/LH Rear Valance components (Refer to Figure M).
b. Remove center and side valences from rear fascia of vehicle.
c. Cut above marked lines at the exhaust openings.

2) Install center valance to rear fascia by removing tape backing just enough to make a tab to pull once part is correctly situated on vehicle (Refer Figure Q).
3) Once the part is aligned to previously marked grease pencil lines, pull the tape backing off using the tabs and press firmly to ensure good adhesion (Refer Figure R).
4) Reach into the loosened fascia and install M4.2 x 18-mm screws into center valance (4 total). Do not over tighten screws or warping of the fascia will occur.
Side Valance Installation
1) Install side valances to rear fascia by removing tape backing just enough to make pull-tabs. Align part to previously marked lines.
