IMO it made the truck. I was chassis slapping and rolling over bad with the stockers. These will pull wheelies, yet can still corner faster. I'm not really happy with these tires, so I have some Losi 320 Zombie's on the way. I hope they provide as much traction, while they are wider, so hopefully will add more stability.
Right now I'm geared 12/54, on 3s it's good for around 50mph.
