the 1inch difference doesnt realy show on this picture, but the stopping power was great with larger discs, locked up the frontwheels doing 120km/h/75mph with 225/45r17 wheels…
1. Remove everything, hubs/disc, caliper and brakeshield.
2. change brakeshield
3. switch the discs from the hub
4. get hub+disc back on
5. caliper in place
6. brakepads and bleed (the brakepads from w123 brakes fit the new calipers)
