Default Torque Spec thread

Hey everyone !

In addition to the torque spec thread that is stickied in this section, I thought I would do a little PDF files with the actual drawings and torque values.
Easy to read, print, and have in the garage.
Describing torques with this is a lot easier than writing the name of the actual part and torque value.

Here you go for the download : DOWNLOAD (updated 2017/3/3)

Please do not hesitate to comment for anything that could correct / make the file better !

Stay up to date !
Simple give me your email address using this link : http://goo.gl/forms/P19InSMaob
and I will send you update warnings about the file

Sorry, no turbro thread here.
But, it's not because the E46 M3 has no torque that it cannot be torqued right, right ?

So I made this : updated

I will add it to the torque thread. Tried to verify as many as possible, but of course I may have made mistakes, so please tell me if you see any !

I made this because we took a friend's car apart in order to repair the RACP, and we wanted to torque everything back to factory specs, which got me started.
I will print this and always leave it in the garage. Very easy to check tightening torques.

Any feedback on how to make it better appreciated !
