just some info on aluminum parts. This diff case is garbage. Even if its barely screwed together you get binding. Tried everything, absolutely useless...... Only wanted an aluminum diff case because the ball stud mount looks like a very weak point on the plastic case.

I didnt install the aluminum arms, but the tolerances for the steering components and the bell crank was excellent. even came with bearings. It is comparable to the aluminum losi one. I have the pro version....I did use a 0.5 shim for the rear hubs. in regards to the bellcrank ..... I can't f'ing believe losi didnt include bearings with their aluminum ones. This was a a good purchase in my eyes.
