I bought a set off Dan under 70 quid i think  2020 Porsche Panamera Turbo Hybrid (V FAST)
2017 Range Rover Autobiography 5.0 V8
2018 JCW Mini Cooper
2018 Skoda VRS

would anyone recommend copper greasing the threads or am i being stupid. Do you still get the same torque grip or will they slip over time? 405 AB exec seats Baltic and Cirrus

Gone in order:

93 Classic hard dash Plymouth Blue
03 L322 Oslo Blue
2000 Disco TD5 ES Epsom Green

The correct torque settings are for dry threads not greased/copper slip/or any other lubes

Words of caution................. If your nuts have been over tightened, it will make your eyes water
If your wheel nuts have been over tightened, you run the very real risk of the studs shearing off and the wheel overtaking you as you bounce down the road. I would strongly recommend that you talk to Land Rover Technical, to try and find out how much over torque the studs will handle before the car becomes a ticking time bomb. I have firstish hand experience of this, and have had to pick up the pieces after 2 Nissan Patrols have lost rear wheels and a Landcruiser a front one He was very luck to walk away from that.
I never get my tyres done at a place where I can't see what's going on, and i'm fully prepared to shout at the Chimp as he goes for a windy gun to replace my wheels. I insist that the wheels are torqued up by hand, again under supervision, it's your life that they are playing with. If they don't like what they are hearing I'm fully prepared to put the wheels on myself, I carry a calibrated torque wrench in the car. Always torque to your nuts, because if you just carry on regardless with a windy gun they may just up and leave you.
And while we are on this happy note, all you caravaners and trailer owners, get a torque wrench, less than £20, trailers will not tolerate more than a 5-10 % over tighten before they all snap, just as your overtaking a lorry on the motorway. And what makes it worse is some of the wheel studs are rated at 54 lb.ft. which is easily obtained with a spanner, let alone a breaker bar. Impact Wrenches are great for removing wheel nuts, and the worst thing for putting them back on again.
This is just an example, this is the very first torque wrench that popped up on Fleabay

Less than £20 and it could save your life and the lives of those around you, would you like to loose a wheel in the fast lane, or how about as your driving past a school at kick out time. Even if the car does not hit anything, what about the wheel? If an ultra light F1 wheel can kill 4 people in an offing, what do you think a heavy FFRR will do? I for one, do not intend to find out. Be safe people and keep your nuts at the right pressure  Yesterday I couldn't spell Engineer... Today I are one!

Got to say agree totally with miggit I always retorque back at home and I always do my own tyre pressures at home that way I get consistency wise words miggit
