Well having read this sticky & recently installed my spacers, I would like add my

While this write up is good, I think that it's really a short cut & short cuts can become interesting at times. With that said I would recommend pulling the hub as it's only 4 bolts away, especially if you are running 20mm longer studs up front. You will also not need an impact wrench because you can tap the new studs out & into pace on a vise instead of trying to fish the studs through the heat shield. You can also visually see the seat of the stud for reassurance of a job well done. I have an impact wrench & prefer to do it as listed above.

If you find your rotor is frozen & won't come off there is a simple solution to this as well. Get yourself (2) Grade 8 1/2"x3" bolts, (4) matching nuts. (4) washers. Fit bolts through caliper bolt holes then place a washer or 2 on the back side then double nut it. Tighten bolt while backing up the nut. Outside nut pushes rotor, inside nut will cause bolt w/nut to push on rotor. You will hear it pop. Rotate rotor 180 & repeat. Rotor will come off easily.

Just another way to accomplish the task folks & it only takes a few more minutes

YMMV

Well said, I had the frozen bolts and it was a PITA to get off.

What is the stock stud length? I have 8mm spacers for the front, so I only want my studs 10mm longer or so because I want to use closed end lugs.

Just measured an extra loose one I had: 39mm to be exact.

You at correct, but they brand them at 40mm. The stock lugs have about 10mm of headroom.

So, if i want to put my 8mm spacer on, i should technically get some that are 47mm, but would 50mm be ok? I've seen some Ichiba studs that are 50mm.

Yes. Get 50mm. You'll be fine

When you measured the stud, did you measure the entire thing, or just the threads?

I just installed 20mm on the rear, and when I go to remove the front wheel there is an extra small nut on the hub that doesn't match up with any of the holes on the spacer, I assume I we can remove this? Someone please confirm this. I've installed spacers on other cars before but never seen this. Thanks!

Yes. You don't need it. It was discussed on page 3:

Will be buying an impact gun and have no experience with one. When pulling the new stud into place, do I need to worry about stripping the stud? At some point the stud will be in, and the gun will keep spinning the nut. Or no?

No.The nut will stop the same way it does when you are installing a wheel.
