Hi Ross, those washers above are .060" (nominal) thick, you won't give up 1 full thread! The photo below shows the thickness, it is really a negligible amount of thread loss.
I put another shot below showing the bolt sitting in the washer. Having said this we do use .125" thick washers but not on the stock length bolts.
Thanks, Gary in N.Y.
P.S. There's nothing gets posted up here that hasn't been thoroughly tested by us between the dyno and customer feedback.
