Front subframe torque moments cq20v

[Tom_]

I have 10.9 bolts and today i was test the torque so i set up a 80Nm on the torque wrench and it clap immediately. So i move on 90Nm and it have a lot of room to clap it...So i think, that will be ok...I put it yesterday on Loctite, so i hope that will be no problem

Well, my experience is different

When you go 35nm + 90deg, you can continue turning the bolt before you hit 80nm. I am sure this is the stretch in the standard bolt. That's why I use 12.9s. I wonder why Audi changed to 12mm bolts and more tightening torque on the later cars?

[Mikes2]

35 Nm + 90 degrees is a higher torque than 80 Nm.

I never had any problems on track with the standard torque. The most important bit is that it's done with the car on the ground

You think? **** i used loctite yesterday, but i get bolts tightened on 35Nm + 90° turn...so now i am nervous, if i could them remove

[Rusty]

careful with loctite or you'll never get them off due to the captive nuts not being captive...

Ok Alex, I do it again, 80NM, i have 12.9 bolts aswell and blue Loctite and i think that will be no problem Thanks everyone

As per my PM Tom, mine used to come loose on track using factory settings.
I now use 12.9 high tensile bolts and do them up to 80nm - no problems

Nuvo : thank you . Do you think that is enough? I will visit a circuit in Brno, so i want to be sure, that no problém will happened , if you understand me

[Nuvo]

Tom, the spec you gave is correct for the M10 bolts used on your car.

I am shocked too and now i dont know whats the true...This manual looks good and its very usefull, but now i am a little bit nervous, if its there a true/correct informations...

Looks like you have your B3 info and you can just ignore my C4 info. I am shocked at the low torques on that diagram, even with the 90 deg turn comment.

I find the same numbers here... http://www.s2-audi.co.uk/tech_articl...r_subframe.htm I know, but the front and the rear are the same torque...Maybe that 90° can be another 60 Nm, isnt it?

Thanks lot, i have some manula and there are 35NM+ 1/4 turn, so can i trust to your information? I know, its more than mine, but i want to be sure . Thank you

You can trust my info for a C4 UrS. 35 Nm is not very much. The spark plugs are 30 Nm. I would check (no pun intended) your data again.
