OK, start here
The 3rd link has all the info, but i used the first link to make mine, it's so simple.I would buy the caliper bracket now, it takes half a day to make them, and the older i get, the more valuable my time is. I did it the first time to say "hey lookey what i done did" the second time wasnt nearly as fun, now on my third,it kinda sucks!
I Used the 12 inch rotors, but you could go to 13. I modified the 12 inch brkt, i shortened it up a little, moved the caliper closer to the hub, and I have 15 inch STOCK ralleys on my car. It's tight. I used a cheap alum. 1/4 spacer, and i felt better. I used the 12 inch stuff for the small wheel, and the 12 inch stuff is on v-6 cars, in other words, easy to get. I have never paid more than 100 bucks for it all. I don't take the used rotors, but i take the calipers, if ya got balls, you could use them i guess, but i use them as cores. The caliper core charge is 50 bucks. I will work on it to make it easier to understand, i am rambling..............
