First thing I would do is put RPM arms all the way around. The whole set will only run around $40, and it's on the top of the list for best all time T-Maxx upgrades, and that's saying a lot with all the parts out there. When driving onroad you're going to be crashing harder, so I would have those arms and a spare pair of bulkheads in the pit box just in case. The RPM arms will lower the ride height a little without throwing the shocks at too much of an angle which is a good thing. Once you get the suspension adjusted like you like it, I would do the clutch and clutch bell. The 3.3 tranny is really stout out of the box, and it should be ok until you put some monster motor on it. Next would be the pro-line road rage tires or something similar, and then the rest is up to you.
