Twisting studs on the street??

[phillym5]

So i was taking off my rear wheels to clean them up from all the driving i've been doing in the Camaro the last few days.. and i had to find a SUPER thin wall socket to get it over the lugs.

Once i got the lugs off... I notice the studs were looking a bit...... crooked.
So i pulled the axle out... and all five of the studs were twisted.
Same on the other side as well. They are Strange grade 8, 1/2 inch studs.

I have been enjoying the fact that the car has been hooking up like crazy in 2nd and 3rd gear once the tires get warm. Actually i have been quite impressed. They are the Nitto NTO5's. 335/19's.

The car has been running 750-760 rwhp... so i would expect it to blow the tires off... but it pulls nice instead.

Anyone ever hear of this from a "street car"... it has yet to see a dragstrip... and has yet to be "hole shot'd".

I had to cut them off flush to the axle... then replaced them with some grade 9 studs. Please don't tell me i have to drill the axle and the wheels to put some bigger studs in there.....

Are you sure the studs were fully press into the axles when installed?

YEah... they were threaded in.

I wonder with the torque it has elongated the holes have you taken one out to inspect the flange?

Yes... i already have installed the higher grade bolts. Everything seemed good. The threads weren't damaged at all... and the new studs had no "slack" while putting them in. However... the old studs could not be threaded out. They had to be cut flush.. then backed out. I have a photo at the shop.. I'll post it in the morning.

These were just installed then I will wait until i see your pic to see what you have going on. It seems like those could be the only two things that could be wrong? But i could be wrong..

maybe a bad batch during the manufacturing process.. if its grade 8 bolts it should say it on there.. maybe the studd were imported from China..

That's some torque and horsepower right there. Good thing you pulled off the wheels to clean them off.
GOOD LUCK and stay safe!

It's hard for me to believe that the studs wouldn't withstand the force of a 2nd or 3rd gear romp with street tires regardless of power. I know that thing reall flies but the stresses of braking and hard cornering more than likely out weigh the acceleration. I can hit 100 in 8-9 seconds but it takes me 5 seconds to stop.....Are you sure they were always torqued correctly?

I originally thought the same... but the Torque was correct. I also thought maybe it was a "bad batch"... but they came with the axles... and they are Strange grade 8 studs... and they are always pretty consistent with the drag race guys.
I spoke with the drag racers(street racers) around here... and they said with the sticky ass tires i have... if it hooks in second... and im running over 750tq to the ground.. it can twist them on the street no doubt. They told me to drill them out and put some 5/8th studs in there.... or don't run such a sticky tire. I want to put the bigger studs in there... but i would have to get my rims drilled out.
Who knows..... i have some grade 9's in there as a temp fix... i'll be keeping my eye on them. A buddy of mine sheered his studs last year at the track in a 2nd gen.... destroyed his entire quarter panel. Im not trying to redue "my" quarters...lol.
