If you want to apply a big optical transformation to your car, then I highly recommend adding sideskirts and a front splitter/lip. As usual, I wanted to choose something else than Maxton design and I found this German company called CSR automotive. Their products looked good and I gave it a try

I was most excited about the sideskirts, I love the design of this "wing-type" sideskirt, just wow
And then the splitter, a simple design which coincides with lines in the bumper
My girlfriend helping with the test fitment
Yes, this will look good (it already looked good!)
Stay tuned...
