F56 Spacers and Extended Wheel Bolts

[offspring86]

I've taken delivery of some spacers (2 x 10mm and 2 x 12mm) for my Mini and want to order some locking wheel bolts for them, but I'm a little confused on what length would be appropriate.

These are the locking bolts available. Based on the standard length being 27mm the 37mm would be fine for the front (10mm spacer), but possibly a bit too short for the rear (12mm). I did think about the 47mm locking bolt, but would it be able to go in deep enough (quiet, at the back)? Am I just overthinking?

Not sure but perhaps simply buy some that have the same length as the ones supplied with the spacers. Or is that not available?
