Bought 2 of these, one for my son and one for myself.
Purchased the one way tube, the upgraded aluminum steering and the wide angle shafts that were previously mentioned in earlier posts and this thing is sweeeeeet!!!!.
The kit itself is very well designed and set up is perfect out of the box.
It is the closest to a full rear wheel cs car out of the box.
I am very pleased with it, so is my son and he's a picky guy too.
I recommend this kit for intermediate and up builder and driver.
