Seriously the D8's turnbuckles weigh a ton. Mine work fine but man are they heavy.
The springs are a nice tuning aid, I found that a stiffer rear spring really wakes this truck up in the corners.
I've got the 1.2x8 kyosho pistons on order for my D8t. 1.2x6 is kinda oldschool. The truck comes with nice wheels , mugen rod ends will allow you to actually use them without rubbing unless you want to dremel your rod ends.
My only real beef is that the CVD's don't have a single captured pin! That's old fashioned IMO. I have setscrews in every one of my D8 CVD's while my Xray 809 has none.
