Yeah I agree I like 15’s on these trucks so I might go with the kit that allows you to use the first GEN Tacoma brakes which I believe you can fit under 15 inch wheels. I would just use the V6 calipers but I need the parts off my front hubs for my rear hubs to move over to a fully floating rear axle and I want the extra 3 inches I get from switching over to ISF hubs up front. Also I really like that this kit allows the rotor to fit over the hub so you don’t have to press out your wheel studs every time you service your rotors.
16.5’s would be fine if I was going to put like 37‘s or 40s on but I don’t think I’m going any bigger than 33’s maybe not even that big.
