I've been brainstorming in anticipation of the Xmods. Maybe we can all post some ideas for mods we can try on our Xmods here to keep us busy until they get here.
The first one I can think of is for lowering the cars. It's fairly easy and pretty much done the way some lower their real cars. I have yet to see the springs, but maybe you can just cut out a few of the coils to give the chassis a lower ride. Think it will work?
