1/10 4WD Buggy

Pro kits tend to be less durable (at least with associated). I know that the factory team kits for the B4 and T4 use a compressed carbon chassis instead fo the stock plastic chassis. They do this to reduce weight (car will then go faster, you will stand a better chance to win the race). But the over time you would be more likely to crack the carbon chassis (the plastic has more flex, it can absorb more of an impact).
