The factory specs were always fine for me.

 

Ok yeah I contacted the mfg and they specify 83 ft lb but said the factory spec 88 ft lb should be fine too.

Did you take your wheels off and re torque the spacers after 50km or whatever as is recommended for wheels?

 

Re torque not needed, as long as the wheel is fully flush to the hub when you begin torquing. The only issue could be if you drop the car down with the wheel face not fully on the hub, then you will hit torque but the wheels wont be tight. 88 is fine. If you want to be safe though and prevent headaches later, clean the hub lips with a wire wheel and spread antiseize. Ive seen many cars that cant get the spacers off after a lease period because they are seized on.

 

Thanks yeah I did clean them all with a wire brush and put some silicone brake caliper lube on the face. I'll re torque the wheels as normal and leave the spacers alone.
