You will need to remove the (2) bottom-most retaining clips in each of the rear wheel wells.

Once you remove these (2) clips, you'll be able to access (1) of the (3) 7mm screws that you will need to remove from the side of the rear valance where it meets the side of the bumper.

Although you can access the front-most screw from this orientation, I found it easiest to remove it from the underside with a nut driver.



256E0F81-4686-4226-9C3E-FD6C0536CE36_1.jpg




Remove the remaining (2) 7mm screws from underneath the rear bumper coming from the side. This makes for a total of (3) 7mm screws to remove from the side of the rear bumper/valance. Repeat on the other side.

Pull the (2) retaining clips from the underside of the rear bumper where it meets the valance from the side. Repeat on the other side.

Move to the very rear of the vehicle and look for the (2) retaining clips on the outer edge of the stock rear valance, and the (2) 7mm screws in the middle of the stock rear valance. Remove these.

Once you have removed the (2) clips and (2) 7mm screws from the underside of the factory valance, you are ready to remove the (4) 7mm screws holding the reverse light housing into the stock valance.

Pull down on the valance from under the car to get a little more room and to see where the (4) screws are. Turn the light socket 90* counter clockwise and pull out of the way before removing the reverse light.



62799A61-1C95-457E-B2EC-18CB2C34ACAB.jpg




One more retaining clip to remove from the reverse light housing to free it from the bulb harness and then pull it free from the rear bumper and set it aside.

Here is where you'll want to crack open that first beer.

Time to remove the black valance from the factory bumper. All of the hardware has been removed and have just a few more body panel wedges to get past.

Work your way from the edge near the wheel well. Pulling firmly in a quick motion while supporting the bumper with your other hand, you'll see how the valance will remove.

Work your fingers up as far as they'll go as a wedge, and you'll have no trouble removing the valance from the bumper.

Tape up along the following line to be sure you don't bump the factory paint while cutting off the factory diffuser. Be sure to check for clearance before cutting. Use a dremel and make quick work of the rear valance.

Too late to turn back now!

Now you are home free! Crack open that second beer and get ready to enjoy your work!

With the stock valance removed from the car, and set down, begin to clip the RTR Rear Valance Diffuser into the OEM Valance.

Install the Reverse Light Housing into the RTR Rear Valance Diffuser using the (4) oem 7mm screws. Starting from the middle, place the complete diffuser unit into the rear bumper starting from the middle. You will feel/hear the "snap" as each of the clips slides into the OEM bumper. It shouldn't take much effort, but be sure each section is fully seated and secure.

Reinstall the remaining oem hardware (2) retaining clips from below the diffuser in the rear, (2) 7mm screws from below the reverse light in the rear. (3) 7mm screws on either side of the rear bumper where it meets the valance, (2) retaining clips on the bottom-most section of both rear wheel wells.

Place Reverse Light Bulb into socket and turn clockwise 90* until "locked" into place. Push reverse light harness retaining clip through the hole in the harness to secure it.

Sit back and enjoy!

Looking good sir!

Grabber you'll be there soon enough. Can't wait to see the rear on yours as well.

That looks awesome! Just curious, why would it not work on a base model bumper?

Chip, it's a whole different bumper all together on the base model. It doesn't have the plastic valence that the diffuser needs to clip onto.

Ok, Trevor, that makes sense. I thought you might could just trim more off of the base model bumper, but then I guess you wouldn't have any slots to clip the new diffuser to, correct?

Nice work man!

Looks like 50000x easier than a Roush quad valence with backup sensors. I'll never do another one of those again.

Damn it! You beat me to it!:lmaf:

Great write up though man! Looks good. Excited to put mine on tonight.

Take a look at the write-up beforehand. I literally covered every step in more detail than you'd need.

My 7mm nut driver was key. Really the best tool for the job.

It'll take 1.5-2 hours tops.

Those look pretty great!

Thank you sir!

Yeeeeee! Very proud to rock these RTR parts from you guys!

That looks awesome! Just curious, why would it not work on a base model bumper?

It will, technically, but it will require an awful lot of body work. Check out my buddy Steve's detailed explanation of how to make this work with the base bumper:

Correct...lots of body work needed to make this happen.

Yup, I've had the Roush Quad Valance in my garage for a few months now, and have dreaded the install, and was never really a fan of how it looked. Always thought the RTR looked awesome in pics, so I waited to install the Roush Valance until I saw the RTR in person.

Needless to say, I have a brand new in box Roush Valance w/ Back Up Sensors and a new set of Corsa Black Quad Tips for sale!
