You're basically paying $750 to increase the speed limiter. The other $1750 pays for the 1-day M School.

With that said, there are only two ways to increase the speed limiter above 155: M Driver's Package or unlock the ECU and get a tune.

Why was it worth it to me? Because if you do not get the M Driver's Package there is absolutely no way to retrofit it. Of course, in hindsight I shouldn't have done it because I ended up tuning my car anyway, but at the time I didn't think that I was going to do that.

TL;DR - If you plan on unlocking and tuning the ECU you absolutely SHOULD NOT get the M Driver's Package. If you do not plan on unlocking and tuning the ECU, it is the only way to increase the speed limiter.
