Thanks everyone for weighing in on this problem. Very helpful feedback. I had not heard of Keensert / Timesert before, but those certainly seem like a good route to go assuming that the female threads are beyond salvage (my eyeballs say most likely yes). I did a broader search on the board and found that some other owners with the same problem had good success with the timesert / keensert https://rennlist.com/forums/996-gt2-...bolt-help.html

I'm thinking the previous had track seats in the car and swapped them out before selling. If you go with a larger bolt the metal sleeve that fits into the seat belt end will be too small. The insert is the way to go.

I fixed a similar issue in my 964 by using a tap from a previous cross thread. I went **very** slowly and took a a lot of time along with using some lubricant. I then used a new seat belt bolt and the threads straightened out just fine...just don't rush. If that doesn't work then you will have to go with the other recommendations of an insert.

Good luck,

Also be sure to keep the tap perfectly straight to the hole. Sears usually has good tap and die sets and lubrucating oil.

My Gearwrench Tap and Die set are the best I've used and guaranteed for life. I've broken a couple and they sent me replacements. Aside from the quality of the taps and dies themselves the holders and ratchets that work with them and are included in the kit make it very easy to keep then straight and running true while applying pressure.

Good luck with your repair.

If you do a bunch of repairs, I agree buy better tap and die set. A one or two of repair, I say Sears is ok, but not harbor freight or JC Whitney.....never buy that crap.

I used my Sears set...

I have a set of Harbor Freight taps and dies - they are ok for cleaning out threads but I wouldn't like to try them on cutting new threads.

So the shop got a new OE bolt from Porsche but tapping the female side was a bust...too far gone.

Shop isn't comfortable doing the keensert / timesert in-house (not the type of work they do), so we're on the hunt for a So Cal shop recommendation. Any suggestions (please)?

I had the same problem and time sert was the answer
It's easy you can do it yourself if needed

By the way: the seatbelt bolt is the ONLY bolt in your car that's not metric. Because of DOT regulations I guess
So if someone replaces the bolt he probably thinks it's metric and a the metric bolt kind-a fits until it gives more and more resistance. Well if you don't back up at this point but apply more force that's the end of the thread and I guess that's what happened

Call BBI Autosport. I'm sure their fabricator can fix this. They might have other solutions too.

Wow, that is interesting. I never would have thought to verify if it was standard vs metric...just assumed metric. Thanks for the tip!
