Okay so I am looking at making so more brackets to fit the porsche calipers, I thought I would get some feed back from anyone interested in doing this and what they would like to see In terms of rotors. Currently I am looking at making the brackets to fit with rotors from the e46 bmw m3 these are 325x28mm with an overall depth of 52.5mm. The other option is the subaru wrx sti rotors which are 326x30mm with an overall depth of 52.7mm so basically either rotor would work with the bracket, the only difference would be the need to redrill the bolt pattern of the bmw rotors, and for the subaru rotors you would need to file the pins on the porsche caliper to fit the wider disc. Both would require hub rings to center the rotor on the hub which i would provide as well.
