    Jk big brake kit and 15" wheels?

    As the title states has anyone tried this combo? I'm wondering if theres a magic back spacing combo that will allow for clearance of the brake caliper. I'm needing to run the j8 brake rotors and I'm contemplating cutting down the diameter of the rotor to the factory jk 11.9" if it wont fit. (I'm running 5x5.5" bolt pattern which is why I need the different brakes) thanks for any input

    Easiest solution...17” wheels. Dynatrac Progrips were close on the wheels I had, at that.

    This is going to sound stupid but... if I run 17s I'm going to have to run 40s on my rig for it to look right. I'm looking at 15s so I can run a 37x14.5r15 toyo mt. This isnt going on a jeep but I'm most deffinatly using a jeep front axle.

    You wouldn't happen to know the diameter of the central hub on the rotor would you?

    Yeah, so close that the weights added inside the wheels need to be installed out line with the caliper.

    No, your good. Most of the Jeeps you see on here are running 17s. Whether they are running 33s or 40s. 17s basically are the standard.

    Dynatrac has a template on their website you can print out and see if your current setup will fit. If I recall, they do recommend 17" wheels minimum.

    This ^^. They won't clear anything under 17" wheels. And even some of them may not fit.

    Yep. I had to grind a little off of the rear calipers.

    Any issues with Progrips on 17” KMc machetes ? Seems like a common combo . Hoping no surprises before I go to install next weekend .
