Rear disk conversion is over powered. It should be partnered with a biasing valve, after master cylinder. ABS kicks in during minor-moderate brake application. Looks cooler then drums...so I've been told.
Christ denied has the tundra racing bbk. He likes it. As does, sparkys Tacoma. Both of them are damn near, if not over 400hp.
6piston, rotora 355 kit...needless to say. Stops on a freaking dime. Repeatedly, fade free. Love it.
You allready have a decent brakes, do to having 4 piston, 11.5" rotors(can't remember size). Compared to xrunners, you have a bbk. Lol.
Torspd has the 6 piston 355 kit for prerunners/4x4. Stops his shit, almost as fast as it goes accelerateing. Hahaha
