Their bolts aren't really OEM and here's why. I was wondering the same thing and wanted to find the part number of those 8 bolts. If you check BMW ETK (item #4), you'll see the part number for those ASA bolts is 11237575488. After finding this out, I went ahead and ordered 9 of them but then realized these bolts are probably not long enough to account for the thickness of the bolt capture. Then I sent an email to H2 Motors (German guys) asking the part number. Here's their reply:
"Hello, nice to read that you like our videos, thank you! Many competitors simply copied our work, therefore we would like to keep this as our little secret. Sorry, but we can not tell you the number. The screws have the same strength as the original screws, they are just 5mm longer to compensate the thickness of the lock. Kind regards" Long story short, they use the same OEM strength bolts but theirs are slightly modified in length, hence not really OEM. I think I'll just stick with the bolts that VTT provides. |

Are the VTT bolts also 5mm longer than the OEM bolts to compensate for the thickness of CBC?

The Vargas bolts were longer than stock. Unfortunately, I didn’t get a picture of them before installation.

It appears the H2 has bigger eyelets for the holes which would be more forgiving during install. Ie the central bolt doesn't need to be tweaked if it doesn't line up.

hey guys. Of course, our bolts are longer to compensate for the capture. Those button heads in the photos were taken prob 2 years ago when we first released these. Those bolts were never shipped. We have sent, and will always send grade 12.9 socket caps. Our bolts are 12mm longer than factory to not only make up for the width of the capture but also use as much of the available thread as possible in the hub. So to hit all points. VTT bolts 28mm of thread, 12.9 grade. Factory 16mm of thread 8.8 or 10.9 grade(not sure which). Our bolts are not only longer, but also stronger (see attached chart). Hope that helps!

I'm probably going to get this myself as a "just in case" sort of thing but it frustrates me that the SCH is common enough to be a worry (on forums at least) but uncommon enough that the effectiveness of the fixes is damn near impossible to gauge... Would the cars with these fixes even have spun the hub without them or been one of the masses that never spun it at all? It feels a little like giving someone a talisman to avoid getting hit by lightning.

Here is a pic of my CBC with hardware from Vargas I just received yesterday.
I'm curious of Torque Specs for the new bolts, and do we use Blue Threadlock.... Also gonna make sure my Crank Bolt did not come loose before installing. [IMG][/IMG]

Just as a practical matter, I'd much rather have external torx than those socket cap screws.

Not enough data. CBC alone only does not make you immune from a SPH.

For all we know, the CBC fixes this issue completely. Until someone spins with the CBC installed, we really don't know if it works or not. It's a waiting game now.... who's gonna win the "Spun my hub with CBC" award first? I'll donate $100 to the first person who does it. |
