I would drive it for a while the way it is. Determine if you have an oversteer or understeer condition. From what I can remember, setting on the front affects the rear and vice versa. There was a thread on here (or myg37) that went into great details how to adjust it based on what you're experiencing.
Fwiw, when I installed mine, set the front to the softest, rear to middle and haven't touched it in nearly 5 years. Given your car is lighter with much different driving dynamics this may not be directly applicable
