YES I have. You should be fine without using the extended studs IF you use the extended lug nuts.
Since I was going to have to change my studs out anyway, I thought I might as well use the slightly longer studs.
The studs on the back wheels are FINE. It's the BRAKE HEAT on the front that caused the studs to fatigue along with two of the lug nuts being damaged.
I am waiting now AT LEAST 30 minutes before I change back to my street wheel/tires after I am done tracking for the day. I also use a breaker bar to LOOSEN the lugnuts as well as just snugging them down with an impact prior to final tightening with a torque wrench at 140 ft lbs
The fatigue point on those extended lug nuts is the little shoulder that goes INSIDE the wheel. If you use your impact wrench like an air hammer then that portion of the lugnut can fracture ESPECIALLY if the lug nut is hot. Also if you try using the impact wrench to break loose the lug nut without using a breaker bar FIRST then THAT can also fatigue the lug nut.
