I have the 37" Ridge Grapplers on my TRX, 12.50 width and IMO it makes the truck look correct. You are gonna lose a little bit of speed on launch but I'm still doing 4.5 0-60 and I still don't have the launch control totally figured out. I have the rogue perch collars and had no rubbing issues on the stock wheels, but when I went to a -12 offset, there was some plastic trimming required to make everything fit. (Truck sits perfectly level)
