SEMA is about more than just Supras with big wheels and roof-mounted tents on everything [“Overlanding is so hot right now,” I overheard someone unironically say]. It’s supposed to be a trade show, you know, where you show your new product to other people in your trade. When it comes to truly new product, this self-contained active aero wing is the only thing that really got me rev’d up. Victor Racing was tucked away in a lesser traveled section of the show, and they were more than happy to show me how it works.
Usually, an active aero setup has to tap into the car’s electronics somehow to tell the wing when to move, for example, when you’re at full throttle or when you brake. The Victor Racing setup uses a configurable accelerometer to turn the wing into an air brake or flatten it out when you’re headed down a long straight.
A friend of mine once built active aero for his LS-powered Miata using a pair of pop-up headlight motors tied into the brake light circuit.
This system doesn’t need to tie into your CAN bus, or your OBD port, or hard wire into your brake or throttle systems. It just needs a 12v power supply from anywhere in your car, and it’s otherwise completely stand-alone, which I found very interesting.
