For all you engineer's and 4runner die-hards, I'm new here(purchased an 07 in April). Over the past month I've been trying to decide between which brake setup I want to do, a mix of stoptech and 5th gen calipers, the power stop z36. Now, after watching videos of other car builds I've got to wondering, what are the dimensions of our calipers and and what else may be a factor in switching calipers. I know some Honda's can use Porsche 911 calipers, is there a Porsche for our 4runners? Or a different manufacturer. Just a thought. Would love more info from you smarties.
