I got some new 17 x 9.5" rims and lug nuts (acorn style) for the rears and wondering if they are secured good enough. I got 4.25 complete revolutions out of the lug nuts when torqued down. On the front wheels I got 7 revolutions. Are 4 revolutions enough for the back wheels. Should it make a difference I'm running 430hp at the fly with 12 bolt posi and 5 spd.
