Captive Nut Holding Diagonal Brace to Body

[Eric-986]

Does anyone know if the captive nut that seems to be welded to the body that attaches the front of the diagonal braces (rear suspension) with the M12 bolt is solid enough to have a TimeSert put into it, or is it just going to snap off? Found out why the bolt in my car was missing..... threads are trashed. Replacement bolt spins at about 25 lbs, can't get to the required 80......

This is on an 09 Cayman S.

Thanks for any words of wisdom.....

I think that will work. In the 986s it's not just a nut welded at the bottom, but a long cylinder that is welded to structure at both ends.

Here's the inside view (bottom panel cut off) looking at the cylinder that the bolt goes into. 'Quarter scale'.

Hello 78F350, I saw your pictures on your flicker site and it seems that auto crossing on a dirt track should be a lot of fun!

It is very fun. On a Rallycross course you can drive the car on the edge of control at 60 mph and below rather than the danger of a track at 120 mph. It can be very hard on the cars though.
Here's a drone shot of the venue that North Texas Rallycross uses:


Here's Woody's old car shortly before he blew the engine. He gave me an awesome deal on the car and my current project is putting a drivetrain back in it for next season.

Thank you for the pic. It's a bit unclear to me, am I looking at the end that the bolt threads into?

Yes. I know that pic is hard to relate to. It's junk in a scrap pile, so zooming out or another angle doesn't help much.
Here... I just did this:



Better?

Perfect, clear with significant welds at the top and bottom......

Thank you again!
