I have these wheels... and some advice........
I spoke with Mark at Carrozzeria about a few issues with these wheels. One of the issues was the bolts. They told me they were 'rare' but let's get real, that's a joke. They should have made the brake disk carrier with slightly larger recesses to told a larger headed bolt instead of sourcing 'rare' bolts,,,, geez.
What I did was purchase stainless M8x1,25x16mm stainless, button head, bolts (check McMaster Carr online. They carry just what you need;

He put each bolt on his lathe and just cut the head down enough to fit into the recess of the black painted carrier section. You could do this yourself the hard way by putting each bolt, one at a time, into a drill and then spinning it while filling the head to a smaller diameter to fit. Then spin the bolt while cleaning it with a scotch bright pad to polish it.
To mount the brake disks to this carrier, I used my stock bolts and just cut them off to about 20mm and filed them smooth at the threads so they went into the holes without fuss. I used NONE of the bolts Carrozzeria sent to me. They're crap. When I took them off, not only were they kind of loose, but two holes had a smaller length bolt then the other holes (like they ran out of the correct ones and just through what they had in that spot). The heads of the Carrozzeria bolts are small also. The button heads have larger surface areas for better 'bite' in the rotor and carrier. Safer, the way I look at it.
If you look at my pic, I also found a front wheel seal that fits the Carrozzeria on the side opposite the speedometer drive. It's a 28mm ID with a 52mm OD and 5mm thick. Just barely fits inside the wheel for a perfect fit. Mark told me I didn't need a seal being the bearings are sealed. But the wheel looks like crap without a seal, plus what's going to hold the spacer in while you mount the wheel??? Would look shitty as dust and dirt fills that area over time. The seal solves the problem.
All in all, I love these wheels. But, in my opinion, you have to be willing to deal with the details on your own if you want these things to look great, and look like an almost $2000 set of wheels. Seems Carrozzeria doesn't sweat the small stuff and leaves is up to the customer.
