hey squirell, graphite make a RC have less flex but you give up durability. Graphite snaps pretty easy, the benefit is it just doesn't flex....unlike plastic that flexes way more which in turn alows you to take harder hits without breaking.....or something.

If your a decent driver on the track, graphite parts will help you drive faster because of less flex all around.

If your a not so good driver graphite is your worst enemy ($$$$$ and easy to break)
