How do you complain about a low speed limit?

Theres a street by my house where the speed limit is 35, and you are perfectly safe going 45. Now, I know this is common, but, there's cops sitting there 80% of the time who will pull you over for going 2 over. They are part of a small municipality in St. Louis called Bella Villa whos income is put on the backs of motorests driving down Bayless rd. I hate that If I invite friends over I have a disclamer as fallows: "The speed limit is 35, drive 30. Make sure that all your lights on your car work including liscense plate lights. Also make sure your tags are up to date. Maintain at least 2 car lengths between yours and the car your fallowing. If you are unable to meet any of these criteria take River City Blvd." I really say this. Still, some don't make it Its also a safty issue. I find myself driving down this road with my eyes on the speedometer 60% of the time glancing up at the road every second or so for just a fraction of a second. I HAVE almost rearended somebody.

So again, what has to be done to get a roads speed limit raised?

Or even better how do you disband a municipality?
