DAMMIT...

So some rims have a sfi rating but NHRA don't care..............
They do care that the lug nut are open at the end and that the thread proturde thru the lug nut.

When i put slick on my car i had to install a drive shaft loop and install much longer wheel studs. my lug nuts were shoulder acorns and i just hacked the end off of the acorn so that the thread could go threw then end.
Never had a tech oficial take a 2nt look at it in 20 year. AND I GUARANTEE THESE TURBO(SLOT/FINNED ALU WHEELS) would never past a SFI Rating.
Just saying......
