Add some weight...
Change the aluminium closed lug nut to open galvanised steel one which need to be match painted.
This add 2.8 oz per wheel (5.9 oz vice 3.1 oz) thus 11.2 oz total which would translate to a lost of .007 hp
Before someone ask, the thread engagement is 16.5mm on a 14mm stud (1.19 ratio), on submarine First Level systems we require a 1.5 ratio so I'm not worry . While its hard to see, there is ~3 thread exposed which 2 of them are hidden by the recess grove.
