I have searched but I cant seem to find where it is. I am not after the package Racing Brake offers. I am just after more information on the adapter you can buy for the standard c63 calipers for you to use the oem 390mm black series disks.

Phil the THRILL, baby!
There used to be a thread on here for aforementioned adapters made in Germany IIRC, and offered in a group buy by forum member Ernst Van B______ (forget the rest of his handle). That thread may have been deleted for violation of forum blah blah, but Ernst would be the first person I'd ask.
Especially since Racing Brake is not offering their adapters for separate sale. (This may have changed)
Best of luck

He changed his handle to dekraboy

That was deleted because the details were being posted in a RacingBrake thread. If you reach out to him he should have the info.

I believe Dads63 had the OEM calipers/brackets with black series 390mm front rotors. Pretty sure he used longer caliper bolts with aluminum spacers to bring the caliper out a bit more.

Thanks guys ill pm dekraboy, I was also wondering if the black series discs will be a straight swap or would I need to get custom bells because the black series is wider they may push the wheel out further changing the et?

Following this with interest
If you could buy just the bracket
Typically I've just replaced front ppp discs lol

Anyone any info? I contacted the person who people mentioned above but no reply.

Thinking of doing the same mod myself. If you have any luck in contacting him please let us know. Cheers.

If you just upgrade the front, there will be braking imbalance.

If this happens, the front ABS will kick in and you'll use only the rears to come to a complete stop, say to avoid a red light camera. As you approach the intersection again, you won't know what to do, because don't trust your brakes to completely stop you.

Slowing down is affected but in a different way, there is more weight transfer under braking and more diving under braking. This weight transfer makes moderate braking feel like oh-sh..braking, again making you nervous about your brakes.

I know because I did a Brembo front only upgrade to my Subaru, which per Brembo was designed to be.. front only.
I tried different brake pads for the front, OEM pads for the rear, all 4 pads of the same type, used my adjustable shocks settings to combat weight transfer under braking (which worked but turning handling was not great). Finally this was 90% solved when I replaced the rear calipers with the OEM Brembo option, used the same pads front and rear and biased the shocks slightly.
Then I go fed up with crashing around NYC potholes (without bottoming out) and loosened the front shocks. The change in handling was just awesome. And the brake diving came back... At this stage I didn't care anymore, I just loved the front softer shocks handling.

Folks, I am also looking for the adaptors.

I would like to go for the OE of Girodisc front rotors 380 mm rotors.

Have we been able to solve the adaptor mystery ?

Please share any contacts for this
