Stiffening plate bolts

[crystalworks]

Uh oh.

Edit: tartilla, here is a link to the thread where this has been discussed ad nauseum. Andrew did some great testing in there and came to a determination about reusing the OE bolts, replacing them with cheaper alternatives, and torquing techniques. https://xoutpost.com/bmw-sav-forums/...llation-7.html

Thank you for the link. Seems I missed that post.

I'm not against the replacement of certain bolts like TTY per say.

My Mack U Bolts at 1-14" and the 1800ft.lb tq spec, I would never re-use them. Despite the extreme cost and poor availability. An extreme example.

Head bolts would be another area of concern.

I'll be yanking my plate off soon, so I'll have more perspective. Hopefully no curses.

Great forum here, by the way. Lot's of good info, and community.

One can have their cake and eat it too. You can order the same grade, size and type of bolts from Belmetric.com for about $20 total. So, by the less expensive bolts every time and torque them to spec and you will always be doing what BMW says, but at significantly lower cost.

You can also buy them from FCP Euro, yes, they are more than $20, but because the are TTY bolts and considered single use by BMW, FCP Euro will replace them for you for life under their lifetime warranty program . Buy them once and replace them free for life.

True, but you will have to pay to ship them both ways. The only thing they refund is the value of the bolts.

Agreed, that is true - makes the $20 bolts look good for sure (and probably the route I would go)

Was just tossing the option out there for the die hard “BMW part number” guys.

I went the $20 route with 12.9 bolts. Won't ever have to replace them as they won't yield at specified torque and added angle.

Guys, let me tell you from personal experience because of my steep drive way that is slanted left to right. If I don't replace the bolts, when I'm at the bottom of the drive way going up or down, the front suspension creaks. Problem always solved by replacing these bolts, therefore it's necessary to replace them. But I always do so when I'm finally done with any repairs that requires removing them. For example, I have new ones waiting till I'm done with all the oil leaks etc I'm dealing with.
