Extended studs question!!
 

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! :)

Hope this helps.

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.

You're a good man AARON! :tup:

You are about 2 years too late...nice try hahaa

Old but still funny :rofl2:

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.

Yep sorry didn't go into detail, but yes that's the plan! :tup:

yea real easy. any hammer will do they pop right out. make sure when you put the new stud in it goes in straight

And you have strong hands to hold the hub if your car is rear wheel drive (maybe use some rubber gloves with good grip)

The installer tool helps too but needs a washer between the hub and tool otherwise the bearing portion hits the hub face. Also stop tightening immediately once it is bottomed out or you'll be in the dark with a grinder grinding off the back of the stud so you can pull it through after the nut has siezed itself onto the stud threads (not having a humongous impact gun probably helps too). Do not ask how I learned this.

Jhill that is right make sure you dont over tighten because you wont be able to get the nut off. (when you put the wheel on it will keep the lug nut pressed in) Make sure you always keep a stud on there so you have something to hold onto while you try to loosen the one you just tightened. I didn't have to use a washer with the bearing installer

Be careful if using lug nuts to pull new studs. Use lots of anti-seize to keep from galling the threads. Get a handful of the lug nuts, because the threads won't hold up after 2 or 3 stud installs. Here's how I installed new studs.

Updated: I got them all installed Wednesday of last week, no vibrations, no weird noises so guess I got everything put back on correctly got my 10mm on and looks perfect my 19's sit perfectly flush with credit card fitment in rear! :tup:
