Order the Team Losi XXX-S front steering blocks. They will npt strip out the screws like the AE ones. This is a big problem, for me at leats. I used to have to replace the knuckles at least once a month, and now, I dont have to at all.
Order some A-Arms, caster blocks, hinge pins, and the plastic arm mounts. Thats about all I ever break. Also, order an RPM wide front bumper; that will save you a lot of parts.
