Thanks for the info.
If anyone has a link to a lugnut that will look like the original with the modification - post it.
By the way - the insert pictured above is a little bit to deep I have been told. I´ll check it on my wheels and update the measurment.
Original BRM Spacers are 3 MM longer then the 8 Spoke Spacers the long spacer is what the wheel should take unless someone has respotfaced the wheels I would make them a hair shorter anyway that way you know they are not bottoming out before the wheel is tight
