Rear spoiler extension
Very happy with the look of the extension. Item definitely gives the car a way better look from the back. Item was packaged very well and arrived faster than expected. Instructions could use some work but their online video they provide does a great job at explaining the installation and make the process so much easier. Would definitely recommend.
Wanted a low profile, heavy duty lip splitter after breaking the cheap ones a couple times. This one was a bit pricey to get to USA because large tariff, which was as much as the shipping, but I’m very pleased the product. And it looks great!
