Base bumper and RTR rear side bumper Splitters ?

The only thing that bugs me on my 2016 is the base bumper oh well so I was thinking of maybe adding the RTR rear side rocker splitters to help the bumper blend with the stock side splitters on the side of the car ?

Any here installed a set on a base bumper, here is a link.

I've heard some trimming is required to fit them to the base bumper. I just converted my base to the premium bumper. I couldn't stand how it looked as well. Now I have diffuser and valence options that weren't available.

How much were you able to find the bumper for?

added the RTR splitters to my base rear bumper but just picked up a GT350 lower valance so i'll be replacing the cover with a premium one.

Pics installed ?

Well fuck if that didn't just sell me on the Roush spoiler.

Where did you get just the side pieces? Did you have to modify them to fit?
