I just ordered a Brabus Wing Spoiler from an authorized dealer/retailer. He made sure everything will work for the GLA45 and Brabus did confirm it will. Good thing is that it doesn't need to be drilled. Some don't like the Aerodynamic package and I totally agree but the Brabus wing spoiler is subtle and not as bulky. It kept the elegance of the car/suv/xuv/cuv/hatchback or whatever type they call the GLA45 nowadays. My wife didn't want me to put one but every time I look at the rear, it just looks empty. I want it to look different. Anyways, I can't wait and I will post once it is done. They're also blacking out and smoking out all my emblems and grill. I have cosmo black paint so this will be a black on black on black build. No, it won't look like a teenager with a BMW and a can of Plastidip. It will look elegant. Pics to come soon!!!!!!!
