Getting roof down while driving???

The smart top chip does NOT allow you to operate the top past 20 mph, and you can set the speed limit by programming the chip. Ive operated the top many times during bumper to bumper traffic without having to stop so its worth the money. Plus you can operate the top with your keypad which just makes all the ladies drop their panties. Fave mod for the z.

The Smart Top will let you go up to 40mph and is easy to change the max setting (at least the one I have allows that). I would never try it that fast, but it does allow for it.

The Smart Top is the best mod I have done. I use it every time I drive, primarily when I pull into my driveway or parking garage, I can one touch get the top closing while I am pulling in. I know it "only" takes 20+/- seconds to put the top up or down, but I've had multiple convertible cars with auto tops and the Z is by far the slowest. Compared to my old S2000, I can almost feel myself aging waiting on the Z top to finish.

Another thing I really like with the Smart Top is when I am walking to the car I can use the remote to put the top and windows down. The Smart Top also allows you to program an "auto-lock" feature on your car to lock the doors once you reach a certain speed, etc. All in all a really cool device.
