I got your point, and generally speaking yes, you are right.
however, while I was checking the Z1 website, I really liked the stillen splitter/lip but it is compatible for 09-12 models. And my friend used to have it, and he got it for track use, and his feedback was positive.
That's why I thought maybe the evo-r or anything similar to Stillen will be find for 2013 and up models ...
I don't need something heavy duty because I use the car on weekend too.
