And so now the rear is done. Honestly, converting the whole rear brakes etc... was a decent bit of work. Getting the first corner was the hardest since I had to hunt for tools in the right size, and read up on things to make sure I do not damage anything. I am sure the fronts will take me much longer since there is a hub change involved as well as possibly making a caliper bracket. I gave myself a couple weeks to do it. I may start today though.
BTW Here is the weight difference for 185 and 205.
185: rotor 10lb, caliper 6lb 14oz
205:rotor 13lb 5oz, caliper 6lb 7oz
