I reached out to PB brakes and they can sell the rotors for $640 for 356mm front set with $200 shipping. I found some nice calipers from a C63 AMG for $450 add pads and parts for that another $100. Still have to make/design a mounting bracket for that. So even for a “cheap” setup that’s going to be like $1600. Can buy the whole shebang from PB for $1875 shipped that’s brand new calipers, sport pads, SS pistons in the caliper, custom powder coated, SS brake lines, and no work trying to figure things out.
