The most obvious part that is needed is a forged knuckle with slight drop. About the most you can do is 1/2 inch drop before you get into the lower ball joint. There are a couple of dropped knuckles on the market but they aren't really a good design.

If you're clever with the forging blank then you can take the knuckle a couple of different ways including having a C body rotor/Viper caliper bolt on deal.

I know how to do most of this so if you guys have the tooling budget I can help with some engineering consulting.
