Question 1

Is the s550 kit difficult to install

Accepted Answer

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).

Question 2

Do I need to permanently modify my vehicle to use the s550 kit?

Accepted Answer

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.

Question 3

Does the app have to be open for the controller to work?

Accepted Answer

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.

Question 4

How does Circuit Mode work

Accepted Answer

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.

Question 5

How does Roll Race mode work?

Accepted Answer

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.
