Bilstein OEM Replacements??

Depending on the strut mount the bolts are integral to the strut mount. I'm saying that because of the added thickness of the strut tower reinforcement plate and the strut tower brace means that less of that bolt is available for the factory nuts to screw down onto, so depending on the thickness of the strut tower brace's mounting plates, you'll need nuts that basically extend downwards so it can thread onto more of the bolt than what is sticking out above the strut tower brace bracket.

Factory strut tower nuts. Notice how they are flat on the bottom. With the added thickness of the strut tower reenforcement plate and a strut tower brace, the factory strut tower nuts won't have much threading from the strut mount bolts to actually screw onto



Bolt 51717895241 has an extension so it will go down and attach further on the strut mount bolt/threading.

I need a few of those for my car, with the M3 strut bar the threads don't even come out the top of the nuts. But at $10.50 a pop, yikes man, $63 for some nuts?!

It's nuts, right?! I found some very nice barely-used ones for half the price from a guy parting cars over at E46Fans.

Yeah, it's not a great price. See if you can get them used off a part out M3 as John in VA said. Lucky for me my M3 strut bar came with them.

Ah - ok, I get it now...Thanks.

The price is steep but it's better than the price of a strut popping out of it's mount.
