Extended studs question!!

AstatenateZ · 07-22-2017, 05:27 PM

So I bought some 10mm hub centric spacers and don't want to run them on stock studs for obvious reasons. I have a closed end acorn tuner steel lug nut. So I need to know, what size stud do I need? I found 50mm I guess I just need to 10mm bigger than stock. Can't find a defeninative answer on what the stock size mm stud is.

TIA!

That's perfect!
So 46mm is stock size!? Great. I found some titanium 50mm studs. The whole thing is 73mm but the actual stud is 50mm. It may be over kill? That seems to be about 20mm bigger. Seems to big.

Are these overkill?

Your original knurled length plus 10mm. It's best you go up to the next closest length unless you are limited to a closed head lug nut.

Those look to be way too long if you say you have closed end lug nuts.

Yes I believe so! I have after market Lugs but they're closed end acorn. So does anyone know what the thread side is? If the whole stud is 46mm stock then what is the stock stud thread size? Really don't feel like pulling off a wheel to find out. But guess I will measure in inches. Convert to mm how long the rear studs threads are and order 10mm bigger than that

If you don't feel like doing measurements, buy two lengths and send back the set that is too long.

OR you can take off the wheel, get a ruler, measure the length from the brake pad to the tip end and add 10mm.

I measured the stud (threads) from rotor to end and it's 1" (25mm)

Chose the 10mm longer than stock. I bought some long studs on ebay and the head length was too long and I couldnt put the brake rotor on all the way.

Old but still funny

Ordered them @AARON ! Thanks man! Heard install is pretty easy, remove rotor / caliper, knock out old ones with hammer, impact new ones on using lug nut / some washers to pull the new stud through? Anything else I need to know?

Don't use your normal lug nuts to pull them through. Instead go to Napa/Autozone/parts store of choice and get some very basic open lug nuts to pull them through.
