Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Ok, here is good one. I am in the process of upgrading my brakes to GT3 MkII (04-05). Everyone told me I needed to buy the GT3 front uprights and associated bearings, bearing car, etc. in addition to the calipers, rotors and pads. Today, I took off the "C2" uprights and low and behold I cannot find a damn difference on them that would make the brakes not work with them. There are some very minor machining differences on how the inner brake dust shield mounts, but the caliper bolt holes are the same size, on the same centers and the same distance from the wheel hub. Everything lines up exactly the same. My calipers should be here on Tuesday so I guess I will know 100% then. Any one know of any differences????
