The problem with the rubber bands (or o-rings for that matter) is that it really doesn't get rid of the slop, it just makes you think it does. The forces and stresses that our cars produce is more than enough to over come the strength of the rubber bands. The car will feel better (less sloppy) on the bench, but you will still have slop while running. That is not to say there is no benefit, as I would expect the car to center better in a straight line (providing you have a good servo), and maybe be more sensitive off center.
I used to use teflon plumbers tape. Just cut a square (maybe 1cm x 1cm) then ball it up, put it in your ball cup, and press it on. It is remarkable how much you can compress this material inside th cup. The down side is that it will eventually work its way out of the cup (usually 3-4 runs). -Jeff

Body bags are nice and thin so they work well for taking the play out of ball cups. Just make sure when you're removing play from your car that you don't add any binding at all. The car will handle much worse if there is a slight amount of binding compared to a little amount of play. I actually think that the cars work better with a little amount of play, theory being that the adjustments on them no matter how carefully done, theyre never perfect, because anything in rc is never perfect, and a little amount of play covers up those inperfections. So if something is a little sloppy, don't worry about replacing it or trying to make it zero play, a lot of how a car is going to handle can be mental too. If you think a change is going to make it way better than you probably will think it's faster and vice versa. That's why when I make changes I try to drive the car with a "lets see how this worked " kind of mentality

I've been doing some reading and is it safe to say that the mi2 likes to run with close or the same springs in the front and rear?

Schumacher sell rose joints (Pt number U728 )
I've replaced the middle bell crank link and the connection between the servo and the steering arm - these joints have zero slop!
You'll need a couple of different screws but I'm sure we've all got tons of these hanging around in our pit boxes!
Cost about £4 ($7) and works a treat

The rubber band trick has worked foe me. Yes the forces will overcome the bands in turns but mine was mainly for the straights and it has made the car track perfect down the straights. I don't mind the slop as the car from the first run has gone straight so to me as long as it continues that way I don't care how much slop I get. The car runs very consistant so the little slop I have isn't affecting its performance. I will say I have my bands on pretty tight and takes a good amount of effort to move them. I have really short ones folded around twice.
I have heard of the plastic bag trick many of times but never actually tried it but from others posting on here and other threads I know it works.

I agree with Weylin. The little bit of slop that's inherent in our cars makes them much more drivable. To me, tightening everything up too much, beside the potential for binding, could make the cars more twitchy and sensitive to imperfections in the track. That little bit of slop should make the car more forgiving.

I remember years ago racing oval I shimmed a car to have zero slop anywhere on the car. Man I practiced twice and the car was absolutely horrible. I took a shim or two out and had a little slop back in the car and it was perfect. From then on I learned that some slop is needed in a car to make it track straight and work properly.
