Just got wheel studs...questions...

Just got my set of BBS studs in the mail. I'm confused because they don't have an end to screw them in with. What I mean is that the outside ends of the studs don't have an input for an alen or torx key to tighten them. So what gives? Do I just tighten them down by hand with a little bit of loctite?

Use two lug nuts. Thread one on to the stud and then thread the other one on till it is tight against the first. Then you can torque them down.

They shouldn't need to be torqued down, hand tight should be enough. If for some odd reason you can't hand tighten them you can do the double nut method. Also, clean the hub threads thoroughly with brake parts cleaner and the loctite will work much better.

Double nut is the way to go. I tighten the poop out of them and use red Loctite. For me, we do at speed tire changes and I have learned many moons ago, that having a stud back out during a pit stop, is a real downer.

If you are not going to do at speed tire changes, don't use too much Loctite. Seems that most people end up keeping their studs when they sell the car. If and when that time comes and you are having difficulty removing the studs, you'll have to take the rotors off and heat the hub with a torch (one you use for sweating pipes).

I got everything buttoned up just a little bit ago. Didn't get a chance to get started 'till about 9:30 tonight and finished by midnight...but that includes dinner, lazy time, phone calls, and waiting for the loctite to set. All in all I probably put in about 2 hours worth of work...I wanted to make sure that everything was perfect as it was my first time installing studs and I didn't want to risk any of them coming loose - items installed were studs, hub extenders, & spacers. Anyways, I took some pictures of the work...nothing impressive but whatever.

Brake Cleaner, 75mm Studs, & 17mm Nuts (I forgot to take pics of the hub extenders before I stated...sorry )


Front Axle Done...you also see the 5mm spacer I need for caliper clearance and the TMS hub extender.










Rear Axle...since I took the hub covers off the front hubs to install the hub extenders, I figured I'd install them in the rear since the hubs are exposed and were pretty nasty - so I cleaned them up and installed the covers.






So that's it - no biggie. Can't wait to go to the track and throw on the other set of wheels...should be a breeze now

Can those be cut down a bit to make them more flush with the rims? Maybe that defeats the purpose. Just wondering.

The purpose of studs is not only to simplify wheel changing, but also to allow thicker spacers to be used. So, for instance, this length allows me to go up to a 12 or 15mm spacer if I decide to go with a different wheel and tire package. IMHO, the extra length does make the studs easier to work with - it gives the wheel more room to come off/go on so it's less likely you'll accidentally slam it on the face of the caliper if it falls off the studs during changes.

What did you finally decide on as far as tightening them them down? Did you torque them tight or just snug them down and loctite them?

I doubled-up the nuts and used red (271) loctite.

Did you torque them(how much?) down or just go until the thread bottomed out?

Just went until the thread bottomed out...once they bottomed out the nuts would just start spinning together so that's where I left it. I checked to make sure that the inner part of the studs weren't hitting anything behind the hub - there was tons of clearance. I just made sure I used a good amount of the red stuff. Seem pretty good to ya?
