Have you fitted these? To my eye, the offset on the disc looks different, but I could be wrong.

From memory ( please dont quote me as its been sometime ) but as i remember the discs for the 456 and the 550 were the same as the 4200's thats hee i think Enzo was coming from

I agree. The 550 is definitely the same. No idea if the 456 shared with the 550 though.

The one thing about EU approval often though is how much does it actually mean?

The amount of approved electronics especially power supplies adapters I've seen over the years that are dangerous, overheat.and can and do catch fire is plentiful. I'm not saying stuff shouldn't be tested and approved but it doesn't mean necessarily it is flawless or 100% safe.
Is it approved though or just made in china with the stamp on

I have found the data on the offsets, at last. Tarox has them.

Ferrari 456 Front (Offset 62 mm)
Ferrari 456 Rear (Offset 81.5 mm)
Ferrari 550 (Front Offset 61 mm, Rear Offset 80 mm)
Maserati 3200 (Front Offset 61 mm, Rear Offset 80 mm)
Maserati 4200 (Front Offset 61 mm, Rear Offset 80.5 mm)

The diameters and the PCDs are all the same. Maserati says that the rear rotors for 3200 and 4200 are the same, so Tarox's measurement may not be reliable, however.

It’s interesting then that FD are advertising their discs as fitting both 456 and 550. A 1mm difference is probably not a hill of beans as it’s main impact will be the centring of the disc in the caliper.

i can confirm that I have the bremos front on my 4200 coming from the Maranello, that i got straight from brembo, not to have to pay the extra to put the trident brand, worth another 500 euros..

One thing that Tarox has probably measured but does not publish is the thickness of the hat of the rotors. I don't know if the wording "hat" is correct for one-piece rotors. Regardless, what I want to mention is the distance between the hub and the wheel. This distance is like a wheel spacer, thus virtually affects the offset of the wheel.

Agreed. Worth investigating though.

I measured this at 7.2mm. I'll release the model and drawings for the OEM rotors once I'm absolutely certain I have the correct dimensions. I don't want anyone using them if they're even a little off or missing any details.

I measured the offset at 60mm, after taking into account some wear but I've only measured the rotor in place (being lazy to just get started). I've been looking through Brembo catalogues to try and figure out which caliper ours is based off of so I can get the centering and rotor width limits. That would be nice to know!

A guy on the other forum was telling me he couldn't get their rotors to fit and the shop needed to cut them down to fit. He changed the pads at the same time, if everything were fresh 1mm could make that difference.

Indeed, hence the probably. So they would have shaved the pads a little?

Perhaps they machined 1mm from the hat hub thickness...!!!?
Noy saying FD and agrucultural in the same sentence here boss...!

Would someone be so kind as to tell me the size of the black line? I won't be home for another three weeks, and I haven't had much access to my car to check it. I've had the hub quoted and ready to go for a few weeks and I want to just order it so I can fit my new brake selection when I'm home and start working on the rears! I wanted to verify the diameter of the mounting face to make sure my hub fits before I pull the trigger on some space age aluminium...

Cheers!
