    Just put 80mm studs on (pics)

    Got my 80mm stud kit from Vorshlag - wicked price, 75 bucks includes studs, nuts and locktite. It also includes a useless allen key. Their smaller studs have an allen key hole. The 80mm ones do not. I noticed it on the site, I figured they just posted a pic of an unfinished or wrong stud. Nope, no key hole. I just locked two lugs on each one when I put them on. Putting wheels on an E30 without worrying about lining up holes or holding the wheel from falling is every bit as wonderful as you think. :)



    (yes I know my rotors are pitted, they're from the previous owner, I have all new brakes but the rotors are thick and the pads are almost like new, I can't bring myself to change them until they wear out)



    Put on two nuts, tighten them against each other:



    Locktite:



    Tighten modestly:



    Loosen the locked nuts:



    Done another stud:



    A few more studs, throw the wheel on, flick the nuts on, tighten, done:

    That's a great mod to do but that's not very much for threads on the hub side.
    6 threads.


    DO NOT READ PAST THIS PoST, IT"S NOT WORTH YOUR TIME. EVERYTHING ABOUT STUD LEGTH IS IN THIS POST.

    I told about the too long stud bases hitting the brake mechanisms, because I felt that somebody could get longer base studs because you claimed that the bases of the studs on first post were too short, and that would lead to major problems. And I do see it relevant.

    In this picture you see an oem e30 rim bolt, the push dial in bottom is set to ~25-26mm which is quite near to an inch. As you can see the threaded section is less than inch.



    In the second picture you see the e30 stock front hub(sorry, I had no separate rear hub on stock), with a bolt turned as deep as it will go(sorry I had no stud so you have to use your imagination), as the threaded section is less than inch as we figured on first picture, we'll understand that inch long section on stud would collide brakes(on rear of course).




    And finaly a third picture, oem e30 front hub, oem e30 brake dics and oem e30 steelie bolted together with oem e30 bolt, same method as in real car. The bolt end doesn't come out from back of the hub.


    This is my last post to this topic, I wish not to argue over this, and don't want to provoke anyone, I just wanted to state that those studs in first post are ok, while longer base studs are not. I hate all the missinfo spreading around net, specially on message boards I personaly use on daily bases.

      It's more than the lug bolts that your car has on now... you can feel the threads behind the front rotors, I checked on purpose. These come out about 1-2mm behind the hub, so the same or more than stock (not that it matters once you penetrate the hub).

          On average, on hubs and hub flanges, there are only about five full threads. The main thing to be sure is that there is at least as much depth through the hub face as the stud diameter, that is where the breaking point is.

          Looks good man. I like the route your car is going.

              There is definately more than 5 threads even on the stock bottlecaps.
              If you feel good about it, that's all that matters a guess.
              Wheels look great.

                The threads dont go into the wheel. The lug stud gos through the wheel, then a spacer if one is present, then through the brake rotor. Not threading into any of the above, then finally threading into the hub/flange. I have a brand new set sitting next to me. 5 thread lines. Oh yeah, these are m3 ones too.

                  BigD: What size spacers are you using? How does the quality feel, look?

                  I am thinking about getting this kit because I will be using an 18mm spacer and was told this is safer than longer bolts. Are the studs as safe or safer than longer bolts?

                    The quality seems great, except they packed everything loose and in shipping some of the threads got slightly dinged. Nothing major but annoying when you're trying to thread a 17mm nut onto a stick with no grip. Once you thread the nut through and the threads clean up, then it's fine. If I had to do it again I'd make sure to write in the shipping instructions to pack the box tightly.

                    The spacers I'm using are 15mm hubcentric (from 57.1 to 73 bore). E30 Groupie can give you more details if you need them. I doubt studs are any safer than long bolts, in that they're all perfectly safe. But it's a big enough pain in the ass to fumble with stock wheels and normal bolts without having to worry about extra length and lining up the holes on another disc inbetween. It's a great mod for stock wheels and the only way to go imo if you get spacers.

                      Whats the offset on the Koseis?

                      As time went on, the factory developed the car each year, making it faster, more comfortable, and capable of handling at higher speeds.
                      You don’t want this. You want the trickiest, most dangerous, oldest model you can find. Only then can you prove to the world that you’re a man.

                        I need to do this, my lugnuts are getting wasted from swapping wheels all the time. plus it would make swapping easier..

                            Brand new set of what? Studs? From the same manufacturer of the studs that BigD is using?
                            I realise that but the thickness of the wheel will determine how many threads go into the hub. The bottlecaps and the stock bolts have about 1" of threads that go into the hub.
                            Even the SCCA requires 8 threads.

                            I'm sure it will be fine....I hope.;) If BigD isn't worried about it, then I have no reason to worry for him.

                              Does anyone sell black nuts with locks on them? I dont want my stuff to get stolen in the great Ohio city
