I have the R1 BBK. It was designed to fit with 17” wheels, but I can assure you it does not. You NEED 18’s minimum.
Here’s the low down. The installation was a nightmare. The provided brackets did not fit properly and we had to machine (I think) 50 thousandths off of it so that the caliper would not contact the rotor. No shims were included in the kit. 5e instructions were lousy as well.
All of that said, the brakes do work well. I picked up a firmer pedal feel and the stopping power is nice. They were a noticeable improvement over stock. I just got back from Baja about an hour ago and they worked very well. But so did all the other trucks with stock brakes.
Overall the look good and work well, but it was an expensive experiment when I had to buy wheels/tires just to make them fit on the truck.
those def look badass and i contemplating on seeing if they were a better option to the alcons, the thing i liked about them is the ligher calipers and the sweet look design. but i also read what you just confirmed on the bad install information they provide and other fitment issues that i ddint have with alcon. i have the icon 17 wheels and i would not want to go with 18s so i guess i just stick to alcon, they do brake really well and stop so much easier than stock trucks do, my brother has a raptor with stock brakes and everytime he takes it for a spin he always has to say man i love your brakes lol. they may not look the best but they are not very visible anyway under the 17s
