The SP2 consists of top shaft, motor spacers, shorter shock shafts, different rear arms and hub carriers.
For some reason I think there was something else but I can't remember off the top of my head. Joe Pillars just bagged up all the parts I needed for the conversion except for the top shaft and the motor spacers because they didn't have those in stock at the time.
I love the car, it's in excellent shape and clean enough to eat off of, I just want to stick with 4wd cars and trucks right now cause that's what I'm having those most fun with.
Trying to race two totally opposite classes from one another just isn't working for me. So I'm consolidating my my rc collection some to help offset the cost of a new ZX5 FS2 and a RC8be.
