1/2'' wheel studs enough?

[9secRR]

my moser axles have 1/2'' bolt in studs. will they hold up or should i upgrade to 5/8''? 1.23 60' (hopefully get it down to 1.20), car is 2700 lbs race weight. i have weld wheels which are soft compared to billet wheels.

5/8 is worth the upgrade.

I think on your stuff considering what ya bent up last year, you may want to upgrade & might find the 1/2 inch is already bending.
I have weld draglites & would like to do 5/8 studs on my stuff. Either that or run both bolt patterns with studs and 10 nuts

If you are questioning/worrying about em, add the 5/8ths.
Your car is light, the 1/2s are probably fine.
Wanna risk your car on "probably"?

I agree with upgrading once you start cutting those kinds of times, but even more so after reading post #3! Most machinist's agree it's okay to go larger as long as there is still going to be 1-1/2 hole diameters to the outside of the axle flange from the edge of the stud (the OEM factory drilled axles I've measured fall into those guidelines). Unless you're changing to a larger wheel bolt pattern, a 1/16 of an inch shouldn't be a concern in a chromoly axle flange.
