I'm still in the planning/assembly stages right now deciding on wheel size for my 88 K5. I am going to run hydroboost and I have already swaped discs onto my 14FF. I am wondering if anyone knows of front brake swaps with newer 1-ton trucks running larger rotors, possibly multi-piston calipers that are available or even a possiblity for a D60. I haven't decided on a wheel size yet but would like to be able to do this in the future. I'm going to run around a 38" tire and have found what I need for a 17" rim, but from what I see from the aftermarket (16" rotor kits) they would require atleast a 18" wheel which doesn't have the same tire selection yet. I'm not sure if the factory versions require 18" rims. I haven't driven a hydro with rear discs yet, I'm only using my M1008 on 34" as a judge that I want more braking power on the street for my K5, which is where I'll be driving for an hour to get to a place to wheel. off-road I'm not worried, on-road I want as much insurance to avoid accidents with idiots in my "grey area legal" truck in PA. Can anyone point me in the right direction? I haven't gone to the parts stores to start taking measurments of rotors and calipers yet, thought I'd ask first. Thanks in Advance.
