I just purchased a set of OEM locking lug nuts ($117.00 at the dealer) for my BS and SL55. Does anyone know what the correct torque requirements are for these cars? I also want to re-torque all the tires when I install the new lug nuts. Thanks

I believe that it is 90 lb/ft

On a C32, it is 82 lb/ft

Almost every car out there I have seen is between 80-90 ft-lbs. Choose 85 and you can't go wrong.

Operator's Manual says 96 lb-ft (130Nm).

Thanks, after closely re-reading the instructions that came with the lug nuts they call for 110 lbs which I think is too high. I think I'll follow the owner's manual. However, has anyone heard of torqueing locking lugs nuts tighter than non-locking lug nuts, I haven't?

does anyone know the wheel lug size for the CLK Black Series? I recall once getting some lugs from the dealership to use for my rims with spacers...they turn up to be too narrow. The mechanic ended up giving me another set which turned out to be different from what the dealership had and it worked. I know usually they have some numbers i.e. M(number)X(number). I believe the first number indicated the diameter and the second the trend pattern. Does anyone know the correct these two numbers for the CLK Black Series wheel lug bolts? Also, what is the OEM lenght for the bolts? I am considering getting the titanium lugs and wanted to make sure i order the right size lugs. Thanks,

I recently sold my BS but kept the MB wheel locks and MB trickle charger. PM me if you're interested in a deal for both.
