Drag/Acceleration Caution RWDs using drag radials and brake snip

[Rakker]

I went to change my rear tires yesterday and found 2 broken lug bolts on each side. I'm assuming this is due to using drag radials and brake snip on a prepped track. Getting the lug bolts out is a pain in the ass btw.

Dang..

That has to be a manufacturing fault. We have much faster and heavier cars with the same 5-stud setup.

WOW! Normally you see broken axles before breaking lug bolts, from the stories I hear. Impressive lol.

Yea likely not from drag radials and also most likely not manufacture defect, but from improperly tightened lug nuts. Torque your lugs down with a torque wrench.. It’s easy to over tighten and stretch the bolts ( once stretched they snap easy) or under tightened it will just play back a forth until broken.

A bolt-on/tuned Stinger with radials on a prepped track won't be kind to the driveline at all but lug nuts wouldn't be my first guess to go. I'm curious now if anyone has found a point that the diff or driveshaft dislike..

How about some pictures of those drag radials!

I always do use a torque wrench

If you were shearing studs (our cars don't have that kind of power), I'd think the shear plane would be where the wheel meets the rotor.

Those are busted on the outbd face of the wheel, where stretching would most likely occur from over/under tightened lug nuts. Not saying you don't torque your lug nuts, perhaps they had faulty heat treat.

It’s not my intent to place a silver lining on the situation; however, how much improvement on your times do you expect to see once the lug bolts are fixed?

None with the heat and humidity we have here in Virginia right now lol

what size drag radial wheel/tire setup are you running?

I went down to 18" wheels 10.5" and using Nitto 555R 285s

What's a good torque wrench that is reasonably priced?

Thank you for the useful, non-moronic answer (no-snark). I'd asked because I've heard that the quality of torque wrenches can vary significantly based on the brand. I have not heard good things about HF, for example. There was one youtuber who worked on their own cars who broke theirs without much effort.

Dammit. I was soooo looking forward to providing a useless, moronic answer!

That’s my specialty.
