I had a rear diffuser up on the FB marketplace and I was asked if I would like to trade for Brembo brake set up, Said they needed the hardware and rotors.So I thought I was getting a killer deal. Well I got the calipers home and realized they did not have any of the bolts (pinch bolts/bridge bolts) that hold the two halves of each caliper together. Now I am on this mission trying to find these bolts as well as the o-rings that go between each caliper. I have searched and seearched this forum and the world wide web and havent came up with anything other than these bolts probably should have never been taken out. Doe anyone what specs these bolts are. I know the front caliper are all the same size and it looks like there is two different Lengths for the rear calipers.
