sounds to me like you want breaks regardless of what everyone else's opinion is of If YOU need them or not so pick up a set from BVM, you can get sport tires w/ breaks (2 1/4" tires) for less then 200 bucks, you'll need an air tank and tubing, and I'd recommend the smooth stop break valve. you'll have 300 bucks give or take in it and they'll be activated via the separate channel on your radio and air driven.

their is a electric brand out there that works with a micro switch (full down elevator activation) but it's pretty much junk.
