A few more notes. From the ADRO specifications (click on any part and scroll down to find this):
"Using computational fluid dynamics (CFD), our team of aerodynamicists tested the efficiency gains of a Tesla Model Y fitted with ADRO’s full body kit compared to a factory car. Our CFD analyses showed a 4.4% reduction in total vehicle drag and a downforce increase of 727 N, resulting from the installation of all four ADRO parts - front lip, side skirt, rear diffuser, and spoiler. This means that ADRO’s Premium Prepreg Carbon Fiber Full Body Kit made the Model Y even more aerodynamically efficient, which will ultimately result in a positive effect on overall range and performance."
I bought a different wing for my car from LM Tuning on AliExpress and it got a little damaged when shipped, so I suggest that you consider using the RPM Tesla Colossus to avoid that possibility.
Normally I think ADRO located in SoCal deserves the money instead of a counterfeiter but they are often out of stock from Korea when the fab is done (I had to wait months). But the aero kit truely is functional!
Best of luck.
