I just finished my H&R spring install and i'm wondering what are the torque specs for the F10? Cant find definite answers on the forums....

- Front Top Struts Bolts
- Front Bottom Nut/bolt
- Front Sway bar links nut

- Rear Top Strut Nuts
- Rear Bottom Strut Bolt

Thanks, AJ

Did you ever gotten this info? I need the specs as well. For some odd reason, forum members won't share Bentley torque specs. This is what I gathered from random sources:

Control arm to steering knuckle
M14 8.8 bolt (replace with new).....80Nm (59 ft-lb)
M14 10.9 bolt (replace with new)....165Nm (122 ft-lb)
Control arm to subframe
M12 8.8 bolt (replace with new).....68Nm (50 ft-lb) + 90 degree
M12 10.9 bolt (replace with new)....100Nm (74 ft-lb) + 90 degree

Road wheel to hub........................120 Nm (102 ft-lb) - I just do mine at 95 ft-lb to be safe

Tension strut to steering knuckle (replace wit new).....165 Nm (122 ft-lb)
Tension strut to subframe
M12 8.8 (replace with new).....................................68 Nm (50 ft-lb) + 90 degree

Outer tie rod bolts ( 18mm nuts, and #5 allen ) : 65 Nm (48 ft-lb).
Stabilizer bar bottom (16mm ) : 65 Nm (48 ft-lb)
Struts .. TOP (3 nuts, 13mm) : 34 Nm (25 ft-lb)
Struts.. BOTTOM (18 mm / 16mm ) : 81 Nm (59 ft-lb)

E92 can't be too far off from our tq specs, as long as the bot size/dimension are similar. If anyone has this info the F10, that would be much appreciated.

The rule of thumb for BMWs is if the bolt is made of aluminum, it's made to be used once. i.e. oil drain plugs.

For lowering the car, none of those bolts should be impacted. Strut bolts are reusable. Oh, use BLUE Locktite for the thread.

DIY thread below, but the OP wouldn't share the torque specs after many have asked:

Oh damn thanks

Why is 95 ft-lbs on wheel lugs safer than the spec of 102?
