Bmw m4 crank bolt capture install ~ diy
I purchased a lightly used BMW M4 COMP 6 Speed and the FIRST Mod on the list was the CRANK BOLT CAPTURE from VVT. This small billet part mounts to the front balancer/pulley and makes sure the crank bolt can't loosen. Theoretically the crank bolt will "never' slip if the factory torque spec is properly maintained. I hope this install video helps and thanks for watching!

Man that's a lot of effort when all you need to do is remove the carbon brace and driver's side intake tube, and go from the top/side.

But, if you can get it from the top, by all means it's the way to go.

Mine just got delivered today! One of those things where it's better to have it, and not need it, vs needing it, and not having it. Be happy as a clam if I never need its added protection :-)

I see you're in Phoenix. I'm guessing the shop is Parts Score. Shocker that a for profit shop would recommend a $4k fix over a DIY $100 fix. If you have the money, do the full fix. But there is nothing wrong with doing the CBC. It has a good track record.

Let me put it this way, no one has spun the hub with just a CBC without money-shifting a 6 speed yet these shops somehow know that the CBC does nothing? Interesting. People can do as they please but multiple VTT full fixed have spun the hub because they didn't have a CBC with their "fix", looks to me like the CBC is what keeps the whole thing from falling apart. Why do people even care at the end of the day, it's a win win situation. You either never spin (yay!) Or you become the first ever to spin (yay!) and become super famous and everyone knows you, and you are the sole contributor to the inner workings on why the CBC doesn't work. I don't know about you, but either situation is a win in my book. |

Thanks for the DIY video!! After watching your way to install the CBC, I went ahead and order the VTT CBC from X-PH.... maybe the best money spent for this car!
