Underbody K-Braces - Bolt torque confusion

Hi all,

Apologies for starting a new post on this, but I would like to clear up confusion over the torque specifications for the Front and Rear underbody braces.
The two smaller braces at the rear and the small rectangle bracket under the exhaust centre I am ok and have no confusion!

Vehicle is 2016reg, 2017MY, V6 S, Coupe (registered late Dec 16, hence 2017MY)

Reason for this confusion is that the info I downloaded from Topix a couple of weeks ago for my chassis# has contradictions depending upon which section you are in…for example

Rear subframe remove/refit
K-Brace
M8 - 25nm
M10 - 40nm
M12 - 133nm

Differential remove/refit
K-Brace
M8 - 25nm
M10 - 40nm
M12 - no mention, information is missing!

I am also pretty sure I have seen the M10 bolts specified as 48nm for the K-Brace somewhere?

Anyway, based on what I have found can someone please confirm if the below is correct and if not, what it should be?

Rear K-Brace
M8 Torx Flange (x2) - 25nm
M10 bolts (x4) - 40nm
M12 bolts (x6) - 133nm
Long subframe bolts (x2) - 60nm +240deg

Front A-Brace
Brace to front subframe (x2) - 70nm
Brace to bodywork (x4) - 48nm

Any confirmation of these torque specifications would be very gratefully received

Thanks to all in advance
 
FWIW a difference of 8nm is diddly-squat. Set your torque wrench for the higher setting and be done with it.
The rear braces on y V8R are subtly different construction so I won't quote their specs.
 
Glad I read this, I’m about to take off the braces on my 2020 r 575,
And assumed the torque specs were the same as I’d read on here,
Could you post the torque specs for the v8 r please
