Trouble with Rotor rings

[eternallx]

Hey Track fam

Wondering if anyone got some input/advice for the problem am having
I bought this car with these custom BBK setup previous owner got from a BMW race team in England when he and the car were stationed in Europe.

The calipers are Gallardo fronts and 997T rears.
Now I was told the rotors were PFC but upon emailing Bimmerworld and some research it looks like I got Brembo hats and rings even though the slots on the rings look just like the PFC ones.

I measured the whole thing to be 375 or 376mm x 32mm
Which I guess that means I cant just get the 380x32mm brembo rings.

Any ideas on who else I should reach out to about this?

Alcon and AP racing are both British companies that make 376mm rotors. They don't look like theirs because the slots in rotors are different but maybe they can help you..

I know you said they are not pfc but those slots look like pfc rotors...

I have v2 and v3 rotors from PFC and these are neither

I'll send this thread to Bimmerworld and they'll be able to tell us

Thanks everyone. Going to get better measurements for Bimmerworld and then they are going to forward it to PFC directly so see if they have any insight.

This replacement rotor ring might fit.

The anti-rattle clips/springs look like Brembo, if I'm being honest.

Rotor diameter and thickness isn't the only thing to consider -- you need to look at the annulus, too.

Coleman Racing can make you any size rotor that you need. Can send them the old ones and have them re made

It would be last resort as I dont want any downtime at the moment.

Dumb question, but can't you just contact the seller and ask what the rotors were?

Those look like the same calipers used from the akmotorsport kit. That kit runs on stock rotors. Maybe the race team fabricated custom brackets instead. You may be able to purchase just brackets from ak to run stock sized rotors. Check their website www.akmotorsport.net. Good luck.

We run the same fronts but not the same rears.
Plus definitely dont want to go back to oem sized rotors.

When seller sold the car to me he just said it was PFC, no model number or anything. And after a new phone I've lost his contact

I would call PFC directly. Their tech support guys are pretty good albeit tough to get on the phone.

Otherwise, maybe Dave Zeckhausen can help.
