Lug Nuts

[Jeff Stout]

You guys are making me nervous. 10.0 car with trans brake and 1/2 studs for 8 years

I think most stud breakage is due to inadequate clamping force .ie lug torque.. Plenty of fast cars on 1/2" studs for years.

Well between Larry and my Brother Bob and the stories, looks like I will go with 5/8". Looks like plenty of meat on the wheel to drill out for Lug Nuts.,

If you DO drill the wheels, wait til you get the studs. Now you are potentially looking at drilling and taping the axles,and front hubs also. On top of that, I am not aware of any sleeves made to go around the stud to sit between the wheel and stud. Just the larger nut and exterior washer. Most of the wheels I have had my hands on slip right over the "5/8" stud fairly tight tolerance. only had one a tad sloppy. Then just a half inch spacer and torque em at 85.

Strange lists 130lb. for torque. Even my 1/2" fronts go 90lbs.

I bent a set of 1/2" grade 8 on a mid to high 11 sec. car. I use steel wheels with aluminum drums (they might squirm more than steel or iron drums; don't know) and now run grade 8 bolts in 5/8". I don't torque over 120 ft lb with lubed threads; check what torque your wheels can stand.

Good decision, REMEMBER, ....it’s cheaper to buy the BEST parts first.....
