Sure .Take the " nut " out of the seat - no problem. Fixes everything !

Thanks for posting; great idea. Tried to do it tonight but my Torx 40 was too small. Gotta get a bigger set of Torx bits. I wonder if maybe they changed stuff in the 2011s to a bigger one. Ah well, just another excuse to buy more tools!

In tension you're correct but the shear load on the bolt is increased during a lateral impact or load. So maybe people don't complain just to complain but you don't understand structural engineering.

Whether or not its enough to cause catastrophic failure would take some analysis. Seat mounting and retention is rather important when it comes to crash safety.

THIS!

No difference!

I do understand structural engineering and you have a point BUT the discussion the other guy was referring to was a guy that said to get a longer bolt. As long as the bolt is fully threaded, longer would make no difference... in this case.

Now... I also agree that you are changing a lot of the geometry of the bolt stresses. Enough to make a difference in a crash? Unlikely but I don't want to find out.

SUX... You're likely fine but the insurance company would have a field day with that... heaven forbid.

May want to take it out and just tell your wife to deal with it. Not being rude, my wife used to complain. She since stopped bc there is nothing I can do about it and continuing to bitch does nothing.

Well the people that were saying no way were likely considering shear strength and not thread engagement. Although looking at the bolt the first 1/2" definitely doesn't have threads that would properly engage the nut. Without seeing the underside there's no way to tell whats happening.

And like you said, I aint planning on finding out. But people considering this should also hear both sides of it and decide for themselves. Shear loads the bolt sees from lateral impacts is increased. Personally I don't care to find out what it is or where the failure point lies because I have no interest in messing with it.

I think you missed the point I was trying to ask......

Say hypothetically the hole has 8 threads & the torx bolt has 10 threads.. Sure I see your point as there is no difference that 2 threads are sticking out underneath the car...

But my thought/questions is... if the spacer Nut takes up (hypothetically) 6 threads of the torz bolt... thus leaving only 2 threads to catch in the hole.... Wouldn't this cause some kind of safety issue?

I'm not complaining I am asking a legit question for something I do not know.

Please read my above...
Does this sound like a reasonable question? I'm just curious because I don't know how many threads are lost by using the nut and if it is or isn't enough to make a difference

Totally agree. Especially with your last few lines!

Ject... I am a civil professional engineer.

IF the nut holding the seat in (not the spacer nut)... Forget the bolt for now... If the nut has 8 threads, then you need 8 threads.

As Synner was saying, we have no clue how far the end of the bolt sticks out the bottom. If it sticks out more than the size of the spacer you put in, and the bolt can still get fully threaded (all 8) AND still sticks out the bottom, a longer bolt would not accomplish anything.

BUT... As Synner and I stated, the geometry of the bolt has changed. No denying that. Enough to make a difference? I didn't do the structural analysis on the bolt, the seat or the car.

Worst case, you get hit in the side and the bolt shears because you changed the force geometry and the seat flys out.... Willing to try it?

Oh, and if that happens and you kill your passenger, you better hope no one ever knows you modified the seat.

That's worst case....

It's a valid question. As long as the retention nut on the underside is fully engaged with threads you're fine from a tension/compression standpoint. But look at the pic of the bolt pulled out and see how the threads are tapered initially. That first 1/2" isn't structural and could cause the threads to shear off if the nut is partially engaged on those and partially on the "good" threads. So having any portion of that inside the retention nut is bad in any situation.

But we've just been sidetracked on the safety of lateral loading on a bolt that keeps you from flying like superman in the event of a crash. I personally view that as a much more critical concern in this instance but thread engagement is critical for any bolt to do its job effectively. Hope that helps.

I didn't notice the tapered section. He's totally right. Those CAN NOT be used to hold the seat down. Chance of failure would greatly increase of you were trying to use the taper section to mount the seat.

Synner uses even larger engineering geek terms than me. .

Thanks
and yes it does help a lot.
