I wanted to make a post showing how I modified my stock base model rear bumper to work with the RTR rear diffuser. I've seen a lot of people asking about adding diffusers to base model cars so I figured I'd share how I did it. I want to start by saying that there is no right or wrong way to do this and that it is in no way just as easy bolt on. It's requires serious modification and work not matter how you choose to do it.
First things first. You need to buy the premium rear valance from Ford ($169.99) and the RTR diffuser ($399.99). I purchased these from American Muscle. The next step was to cut the rear bumper. I cut the rear bumper at the lower part of the seam on the bumper. Then I drilled slots for the clips on the backside of the valance to snap into the bumper and hold it on.
The valance leaves a slight gap between the bumper and the valance right above the exhaust were the bumper curves towards the wheel. You could probably leave it be but because I am so OCD I had to come up with a solution. I came up with the idea to make the bumper look like the factory one piece base model bumper.
So to eliminate that gap I actually had the premium valance molded to the bumper. Filling the gaps perfectly so that it had the same flow and look as the stock bumper. I painted it to match instead of the flat black so it looked like a factory one piece bumper but with RTR diffuser installed to give it a way more aggressive look.
It was a lot of work. Not just a simple bolt on. But if you take the time and do it right I think it turns out pretty bad ass. The alternative is obviously to buy a premium rear bumper, valance, diffuser, and have it painted. But when I did the math it was more cost effective to do it on my own. Plus now I have a customer rear bumper that I built which is pretty cool. Just wanted to share with everybody. Curious to see what everybody thinks of my work.
