I drive around town on 33s. race on 28s. it came factory with 4.88s, but yeah different for sure. Waiting for nice weather then i want to bolt on some paddles and play in the sand. I have had it in the hills and it didnt have any problems. Im not a rock crawler like most on here. Just a die hard Toyota guy. Thought i would mix it up a bit ha. So far it has either impressed or pissed off some people. The camaro guys watch me drive to the strip and swap to the drag tires and run faster than them. scratching their heads haha. kinda funny. But i can say this. That r150f is a tough sucker. i have beaten on that thing. Built it myself too, just used the marlin parts.
