Hi Guys.when Installing My New Hoshino Impul Wheels On My 73 240z I've Noticed My Wheel Studs Don't Stick Out As Far And Therefore I Don't Have That Many Revolutions On My Nuts When Tightening Them.does Any One Know How Many Turns I Should Be Getting So There Are Safe? And If I Do Need Longer Studs Where They Are Available.thanks.

dont know about turns but you might need extended ones...try ARP..they are strong for sure.

You should have at least 1-1.5 stud diameters of useable threads. So, since your studs are M12x1.25, you should have 10-12 threads engaged in the nuts ((12*1)/1.25=9.6 and (12x1.5)/1.25=12). Some lugnuts have a pilot with no threads for the first 3-4mm, so be sure you have 10-12 real threads. 10 is MINIMUM, 12 is recommended.

that's brilliant.i'll check this week on how much thread there is.thanks guys.
