Alright so iv fitted my new PM rims to my 08 St Bob with my matchin PM disc's. Next modification is dual disc upgrade upfront. Plan is to to purchase another matchin disc and 4-pot PM calipers upfront. As i also have a PM matchin disc on the rear i will only need to upgrade to a PM rear 4-pot caliper. Has any1 had any experiance with these parts? also iv heard that chrome calipers are no good aas it keeps the heat in, is this true?
