My rear drums and shoes are about at the end of their service life, so when I do the hydroboost conversion, I'm going to bite the bullet and do the rear discs as well.
I know it's been posted both here and at Pirate, but I can't find the posts at either place. What I know so far is that the rotors have to be from a 1/2 ton Chevy truck ('90-ish K1500 pickup was the most common I seem to remember), can't be any wider than 1.25" (ie: no HD rotors), and according to the specs on TSM's site, must be 11.56" diameter (11 9/16"). So I'm looking on Summit, and all the rotors I can find for 1/2 ton Chevies are 1.283" wide and 11.61" diameter. Given how small the differences are, is this still usable? I want to be completely sure before spending 200 bucks for a pair of rotors.
I also remember that the center hole on the rotors needs to be machined to a larger size. Anyone remember what size it needs to be?
