A question for all the people who have fitted H&R wheel spacers to their xk's.
What is the correct torque for the spacer nuts.

 

I would call/email H&R if that info is not on their website. I suspect, but don't know for sure, that it's the same as the torque spec for your wheels. See your Owner's Handbook. The spec for my 2009 is 92 lb.-ft., which may be the same for your car.

 

My H&R spacers (3035635) installation sheet says: "Torque to your factory wheel-torque specifications." For my 2012 XKR that would be 92 lb.-ft.
