I went with the PowerStop kit from Amazon for the 231mm Tundra brake upgrade, also upgraded the hose to stainless steel while I was there. The brakes have been great; they feel a lot stiffer than I expected, which I guess is a good thing? They're super smooth though, much nicer than the rotors that were on there.
I went with the Milestar Patagonia 265/75r16's and I've been really impressed with them. They are my first set of M/T tires and they ride smoother than the cheap all-terrains I've used in the past. They do have road noise but it's really not noticeable unless you have the radio/AC off and are listening for it. They rub a tiny bit at full lock in some situations, but I'm also running the 2nd gen taco "snowflake" wheels, so that might mess with the spacing.
I got them stuck once, trying to crawl up a hill made of loose dirt right after it had rained, in 4HI, and at 34psi. So not really the fault of the tires

I'm excited to get them out on more trails though!
