You said without spending any money unless I read wrong???
raptorman57 hit an a couple of freebie mods. If you can solder split that battery pack up, if your running the standard 6 cell, 7.2 volt pack. Make it 3 cells on one side of the front axle, and three on the other side. Just pay attention when you take it apart, so you put it back together with your positive and negative poles in the correct place. He also said narrow up the chassis. You can do this (which is good) but it's going to take a little work. You probably won't be able to use the skid plate that comes with the kit, but if you have an old cutting board (not wood, lol), you can cut a piece the size you need. With the AX-10 tranny and chassis plates you will most likely run into another problem; fitting the trans inside of the chassis plates once narrowed. You can notch out one of the side chassis plates so that the motor extends about halfway over the side, but be sure and brace the top of that plate if you do. I take no responsibility for any modifications:twisted: If you can get it narrow enough however I would move the top of the shocks to the outside of the chassis, and use short standoffs.
The next thing to do is get rid of those ridiculously wide, side body post. The way they are made with the hex shaped base you can drill through them and make top body mounts. Here's a huge difference, otherwise you'll be getting hung up on those all of the time.
This is just a matter of preference, but I wouldn't worry about trying to triangulate the lower links until I had some money to spend on parts. What you can do though, is move the lower links inbound at the skid, so you don't have those sticking out there to get hung up. When you get some money dump the three link setup, and then go with the standard 4 link, or triangulated upper 4 link.
You may be able to flip your shocks upside down to lower your c.o.g. a little, but you'll need to mess around with the lower mounting to make sure it doesn't bind throughout it's range of motion.
