Also changed the rear to new OEM discs with the old pads as they had plenty of life in them.

The Girodisc are 8% larger (340mm vs 317mm) and fit using the stock caliper with a reduction in weight from 9.0kg to 7.8kg per disc.

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.

Outcome without a verified action link

Checked out Parr/Cargraphic who are the EU Girodisc supplier and it worked out more expensive.

POST 1 / ORIGINAL POSTEROriginal post

Upgraded the front rotors from OEM cross drilled to Girodisc slotted. The Girodisc are 8% larger (340mm vs 317mm) and fit using the stock caliper with a reduction in weight from 9.0kg to 7.8kg per disc. The increased diameter provides a larger effective radius giving more braking force for the same system pressure. I really didn't want to go down the Brembo BBK route requiring almost a complete new disc/caliper system and pressure/bias changes. Here you can see the quality... And here the size comparison with the OEM... It's a very easy install, the only difference to the usual disc change is the addition of the 12mm spacer to move the caliper further away from the arm. The spacers are included in the kit together with 12mm longer caliper bolts (strangely Porsche part numbered?). Finished... Thanks to Craig at rennstore for all the info and help... Now I just have to see how they compare at Bedford.... :thumb:

POST 2Original post

Nice one, did the Girodisc stuff come from the US or did you get it over here?

POST 3 / ORIGINAL POSTEROriginal post

From the States via rennstore. Checked out Parr/Cargraphic who are the EU Girodisc supplier and it worked out more expensive.

POST 4Original post

Nice job :thumb: Did you have to change the pads as well? TB

POST 5Original post

very good, be interesting to see them in action, weight savings with bigger surface area is certainly a bonus what pads are you running ?

POST 6 / ORIGINAL POSTEROriginal post

Running standard pads. I was told not to use new pads with the new discs by the supplier. Also changed the rear to new OEM discs with the old pads as they had plenty of life in them. Did the Pagid bedding in procedure.

POST 7Original post

interesting always had new pads with new discs, any reason why they said that ?

POST 8 / ORIGINAL POSTEROriginal post

Don't really know but they specifically said don't use new pads... :dont know:

POST 9Original post

Good job, is this another potential mod I see before me?? Interested to know how you get on with them :thumb:
