Time to show off a couple mods I made:
1) I bought some extra bump-stops, cut one in half, and added each half to the rear shocks to increase the stock bump-stops' height by 50%. This helps keep the rear frame of the rollcage from smacking against the axle housing.
2) I bought a set of Traxxas 49mm camber links (part number 3643) to make adjustable steering links, then I added a bit of toe-out. The truck is more stable now, and easier to recover when it starts to traction-roll. I also bought a set of Dubro 3mm washers to use as shims to take up the extra space around the steering link ball-ends attached to the steering knuckles, because the ball-ends are not the same height as stock. They work fine once shimmed snug, though.
