A bunch of us had those carbon center shafts in our hands and they are very light...but none of us bought the bullet and picked on up.
In regards to "Blue" I am removing the blue aluminum steering blocks. That, along with the aluminum front carriers adds up to way too much unsprung weight...Although there is absolutely no slop in the steering system, taking a shot into a wall would transfer ALL impact energy through the suspension and directly into my poor little servo. I guess I need a "weak" spot somewhere. For those Tamiya Track locals who want some bling bling Square Steering blocks (C1/C2) come see me at the track this weekend.
