These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

Putting an order into ECP for discs and pads, have decided on Pagid discs but they are showing two sizes for the front of my 3.6 C2. One are 67mm high, 26mm thick and 318 od, the other are 70mm, 32mm and 330od. I'm thinking the bigger the better but can anyone confirm?

POST 2Original post

Only one size will fit the calipers you have. I suspect the larger size is for the turbo brakes but I don't know the size for sure.

POST 3Original post

Standard size is 318mm on the front. C4S and Turbo etc had larger.

POST 4Original post

Can 330mm discs be used with spacers and larger pads?

POST 6 / ORIGINAL POSTEROriginal post

Thanks all, I took the old ones off first so I could measure and be sure, 318 front, 299 rear.
