Once the OEM wing is removed and a fused 12-15v DC connection supplied, the bolt on kit can be installed using common tools in 30 minutes (depending on the installer skill level).

No, it is not required. For the s550 GT/GT350/GT500 kit, there is a recommended but optional 6mm hole drilled inside the trunk for additional airbrake support. The mounts on top of the trunk are designed to fit inside the footprint of the OEM spoiler.

No. The controller will default to the Circuit Mode behavior. This behavior works well for the street as well since it will remain in DRS (fuel economy) mode the majority of the time.

The wing remains at minimum angle until the vehicle takes a corner or hits the brakes harder than the user defined g-Force thresholds. The wing will return to minimum angle once the vehicle is accelerating below those thresholds. EXAMPLE Corner g-Force is set to 0.6g Corner wing angle is set to 10 degrees Brake g-Force is set to 1.05g Brake wing angle is set to 30 degrees Once the car exceeds the corner g-Force, the wing will remain at the corner wing angle until the following: Move to brake angle when the g-Forces exceed the brake g-Force threshold. Move to minimum angle when g-Forces are below the corner threshold and the car is accelerating.

If GPS is enabled and active and the vehicle speed is 5mph or less, the wing will move to the parked angle to shed water, snow, etc that may land on the wing surface.

The wing remains at a maximum angle until the vehicle reaches the user-defined begin speed. It gradually decreases the angle until it reaches the minimum angle at the user-defined finish speed. EXAMPLE The driver determines that maximum traction is needed until 70mph so the begin speed would be set to 70mph. Minimum traction is needed after 100mph so the finish speed would be set to 100mph. The wing angle will gradually move from maximum at 70mph to minimum at 100mph then remain there.
