So if you’re planning to roll the rotisserie outdoors across dirt or gravel without this kit, it ain’t happening. The quality is solid, but 1 of my tires was losing air. I contacted Jason at Redline and he sent me a new tire/wheel so I’m good to go now. Pay attention to the fact that the wheels in the center mount higher than the standard wheels. This causes you to have to raise the car higher in order to rotate the car to clear the larger wheels. I think the price is a little high for what it is, but if you gotta have it, you gotta have it.
