Lugs/Studs - when to change?
I was taking off my wheels the other night to put the track pads on and started to think how many times I've done this in the past 2 years.
They were getting kind of ratty from all the impact action...
Do you guys change the lugs/studs out for new after so many mounts/dismounts?
I assume after a while they'd start to lose their ability to hold torque.

Not trying to hijack the thread, but I had multiple problems at the track this past weekend with the jacketed lug nuts getting stuck in the impact socket. Any suggestions? Does anyone make a solid lug nut without jacketing for the track?

I have never known anyone who broke a properly torqued wheel stud. One guy swore up and down that his 3 broken studs where torqued, but when we removed the wheel, the two remaining lug nut were finger tight. With cyclic loading the studs break due to fatigue. The remaining 3 wheels on his car were torqued.
I raced a Fiero for 11 years with the same stock wheel studs without a failure. The wheels were on and off every other weekend during the AX/Timetrials season.The peak cornering loads on my G-Analyst were typically around 1.25 G's on R-compound tires, which is probably a lot more than GM ever planned on the lowly Fiero/Grand Am/Chevette suspension. I replaced the lug nuts 3 times over this period because the hex was wearing and difficult to get out of the Snap-On Flank Drive socket I used to torque wheels.
My 96 Grand Sport did 5 seasons without changing studs and the Z06 is on the 3rd season. Your mileage may vary.
By the way, I enjoyed your event at Grattan. Erik

I don't bother with the plastic caps.

Thanks for the replies.
I'll probably pick up some new lugs just because my cheapo Harbor Freight impact sockets have a tendency to round them off a bit.
Erik,
Glad you had a good time and looking forward to October. I need to get some of those scrubs
Going to pick up the car tonight and trailer it home.

I have some hardened open ended lug nuts I got from NAPA.

I would mount that manifold block rigidly to frame somwhere. I don't think the mass moving around does those flex lines any favors. Maybe even ditch the line-lock completely if you are not using it.

Then you are out the cost of a new socket in addition to the nut. For years GM used them on a lot of their other cars but not Corvettes. I was really disappointed when they went away from the good lug nuts with the plastic covers. I use a set of lug nuts from a 97 on my track wheels. They work fine but the ones with the threads on the outside for the plastic covers stick out further and are easier to get a wrench on. The lug nuts that GM used for the ZR1 and GS wheels are excellent.

You'll feel them start to get harder to spin the nut on. Replace them before it gets completely jacked up with your race tires on at the track, in the rain, with no other way home.

Wheel studs
If you have stock ones definitely replace them with ARP or similar. I would get them an extra 1/2 in. in length in case you use brakes and or wheels that need spacers.
I just saw a Camaro that had stock studs after two seasons and his repair bill for replacing the front end of this car was rather expensive.
