what i have done is;

25nm

50nm

one rotation of 90 degrees

Then set torque wrench to 110nm and tightened all until it clicked.

I remember a couple of them already being 110nm when i went round so moved on, now im beginning to think i may have to buy new bolts and do it again! id rather do this if my method is not acceptable.

I beleive the final 90 degrees would torque the bolts further than 110nm!
