That design is for the DSM, using 1g 3000gt VR4 calipers and rotors for a mustang cobra, but I don't recall the year. There really is alot in the R&D of the brackets. The ones on tuners nation are made for the Galant, with 1g 3kGT Calipers and 2g 3kGT rotors IIRC. If you're going to make your own, go all out. Pick the rotor and caliper you want and gets to measuring, but I doubt someones going to give you the formula to their profitable idea. Just my humble opinion of course.
