Please help identify Brembo Porsche Calipers?

[BON 3]

Guys, I need some help please in identifying calipers?
My mate got some calipers and was told from RS2.
The numbers shown on them are as follows:
20.4673.00 Rear
20.4564.00 Front

Does anyone have a clue what these are off?
I think he has been duped! (For the want of a better or more crude expression)
Any and all help welcome!

A pic would help I do a lot of work with Porsche Brembos and can recognise most of them.

That part number isn't a Porsche part number so they could be Audi parts but it doesn't look like an Audi number either so is most likely the Brembo number, see if there are any other markings on there.

I think those are casting numbers, would suggest posting a photo and measuring the piston diameter and the distance between the mounting holes

Thanks, will see him tomorrow and ask him for photos as at his house.
Would be great if you could help.
Any particular angle/angles of photo required?
Cheers

Will get him to do that thanks.
Arranging for him to send me some photos tomorrow.

it's also possible that they could be chinese / eastern knock offs of brembo's, they're appearing in big quantities now too

Sorry meant to ask, is there anywhere specific to look for markings on Brembos?

[wildoliver]

No specific pics just some pics to see what they look like, a combination of method of pad mounting, radial or axial caliper mounts, amount of pots and colour of caliper can narrow most of them down pretty easily.

I'd be interested in seeing some of these chinese knock offs, would be good to have a poke around one and see the quality, if weight and quality are ok then I'd be tempted to use them as some of the Brembos I use are getting on a bit and showing their age now, sadly I tend to find chinese stuff is either really impressive using someone elses design and up to date manufacturing facilities with skilled staff but saving money on the labour and development costs (by copying) or utter sh**e that is useless at best and dangerous at worst.

Those numbers are as S2_WOT says the Brembo casting numbers and as far as I know there is no cross referance data for these numbers...

I have tried to find one in the past... With no luck..

Only later Brembo's made for Porsche actual carry the Porsche part numbers...

Post some piccy's up and will see if I can help...

Too much of a risk for me.... I would not like to find out they were not upto the mark when my kids & wife were in the car!!

[s2_wot]

, totally, I'd skimp of loads of things but anchors and rubber are a big no no for me.

I don't think these are fakes, just not RS2s, but could be wrong about RS2 thing.
They are second hand and seem to be Brembo for definite.

if you google the part number you have listed you'll find several discussions about that part number; 1995 993 Carerra 4 Calipers HTH

Cheers, really useful, it would appear 993's.
I would still like to post the photo to get confirmation of their origin?
Just don't know how to on this site?
