i have the front range Tacoma break kit on my 85 and it is one of the best mods i have done.
i just test drove a 85 4 runner with high steer fj rotors and ifs calipers (same as my old setup) with land cruiser master and i felt like it would not stop!
i let the guy drive my truck and he was sold on the kit!
my set up is 92 4 runner master and booster, tied up lspv, front range brackets for callipers, swap knuckles from driver to passenger, ifs hub turned down to fit inside a factory 2000 tacoma rotor, and tacoma calipers.
added bonus is to change the birf all you have to do is take off the hub dial. pull the snap ring and remove the 8 bolts holding the spindle on the knuckles. !!!!! no wheel bearings need to be touched!!!
also to do a brake job, just pull the caliper!!
only way to fly!
