That huge space is the wheel adapter. 1.25 inch. They bolt to the stock bolt pattern to extend the bolts to push the wheel farther out. I got them to fit the fifteen inch wheels, the black ones. I got fed up with them cause they were too close to the caliper for my comfort. So I took the wheels off. So I still have the adapters on with the stock wheels. These adapters install on top of the rotors. So to get new rotors the adapters come off.
Axle>Rotor>Adapter>Wheel.
The truck with the stock tires and wheels with the adapter gives it a slightly bigger stance compared to no adapter at all. I like the way it looks. She pulls to the left a little but My tires are worn and something causes it to wobble when the brakes are applied around 35+ MPH and it wobbles around 70. Not serious wobble but enough to annoy the hell out of me. Still looking into it. Been to hot to work outside. I hope that helps clear things up I have never been good at explaining things.
Correction when I say stock tires I have 265/70/R16 BF GoodRich All-Terrains on there.
It wobbles at those speeds because that is the natural frequency of the vehicle 35 and 35 x 2 so if you would add weight or remove weight it would change the natural frequency and eliminate the shimmy. I'm a vibration analyst and a Production plant so vibration is my specialty.
