I decided after extensive reading that their kits are too hit-and-miss for me. I didn’t want to be waiting on them to send parts or answer questions as to what to do to make them work. Seems there were plenty of people who ended up taking a long time to get those brakes to work, which might be ok for a project car or something you didn’t need back on the road right away. Which is too bad because they’re awesome looking brakes and something you don’t see every day. I went with Wilwoods 16” 6-piston fronts/ 14.25” 4-piston rears. They’re awesome and no issues installing them.
