Ok so i was ready to buy the parts to do the tundra break upgrade then i noticed that on rock auto under my 2002 4runner breaks they offer a z36 upgrade kit for the 4runner which has 319mm rotors and the tundra is a 231mm so my question is which is better both say they our best for towing which i will be doing is there difference? Is the tundra still the better option. I have 16” rims with no lift 2wd and dont want to modify too much any advise would be much appreciated
You're confusing rotor and caliper sizes. The 199mm and 231mm are caliper sizes, the 319mm you mentioned are rotor sizes. Tundra calipers go with thicker Tundra rotors than 4Runners have, that's their main advantage.
