Interesting morning today...

There are 3 or 4 different 10.9 grade axle bolts for Boxsters depending on year & trans application.

Yes! Also the S model and the base model use different bolts as well. Quite a plethora.
The 12.9 grade is terrific, I'd recommend it- I found my stock bolts starting to strip, even though I was not over tightening them!

Good to know. I torqued these bolts a month ago but don't recall if they were totally cleaned/degreased.
