What exactly is an RCX? I'm guessing it has something to do with suspension because it's in the suspension forum.

I'm going to rant off topic a bit here but why does everybody abreviate so much that you are clueless to what anything actually is. It took me 3 months to figure out what SLR was. For example, after I joined XOC i found out I had an LSD then I went to SLR and bought an ARB.
