Damn, wheel bolts. Who the hell would put wheel bolts on a wheel that is not hub-centric? Obviously some brilliant engineer who forgot studs are better than bolts.

I forgot how much fun these cars are.

The crazy thing is that several manufacturers STILL use the bolts! I have no idea why; even though the hubs/wheels are of course designed with the appropriate geometry, do they think it's "fun" trying to mount a 35lb wheel+tire one-handed while the other hand -- the weaker/uncoordinated side of course -- attempts to start the lug bolt w/o cross-threading it?

Studs are a good thing...for a track car, they're a necessity IMO

Yes! I get to help!
Back when I was a Distilled Petroleum Distribution Engineer (Pump jocky at a full service gas station), one of my many tasks was mounting and balancing wheels, fixing flats, etc. I always got ticked off about the wheel bolts too, until I discovered a trick. Sit facing the car, stick your legs under the car, rest the tire on your thighs or shins, centered on the hub, and lift into the approximate position with your legs. This leaves both hands free to thread two or three bolts, which'll hold the wheel on while you insert and tighten the rest. Voila!

Yup...but some of the better ones provide a 4" threaded rod...screw it into the hub and you've got something to hang the wheel on while starting the bolts...shouldn't be too hard to make something similar..

My first car was a '58 VW and changing the tires was a challenge until I "discovered" that method of balancing the wheel on my shins while locating the first bolt. I once read an engineer's reason for bolts over studs on road wheels. I'll try to find it again.

There is no engineering reason for using a bolt in place of a stud. It is a bean counter issue.

Brilliant!! (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif) Simple and effective!

Through a couple of threaded rods in with the spare. Then install them across from each other on the hub to hold the wheel in place while you install the bolts.

I usually do the "sit on your ass and hold the wheel with your shins" method, but something's getting dirty doing it this way, and I never did like the idea of having my legs under the car with out a jack stand as back up.

My Passat came with one. VW calls it a "Tommy Bar". It works great on the 914. I picked up an extra one at the VW parts counter. It cost me around $3.00.

Studs suck, have them on some other car, everytime the wheel is removed or replaced, it drags a bit on one or more of the studs, eventually it will wear the exposed threads. When using the leg/shim support method of botled wheels, there is little chance of bugging up a thread, and even so, it is much easier to replace a bolt, than a stud.

I think them Germans were up to something. Bugger up a thread on a stud, and you got potentially a headache of a replacement, bolts, no sweat.

My 914 has influenced my commercial lawn mower designs. I had an ouside company develope a new hub drum with studs for the rear drive wheels.

There are other things that the 914 inspired but this is the most noticeable on my machines.

Go to The Gizmow mower

And look at the video.

Slick mower Mark! The video really illustrates the cam controlled front wheel steering. Made it all the way through the AX course without some much as bumping a cone. (IMG:http://www.914world.com/bbs2/html/emoticons/driving.gif)

The jack handle on mine was small enough that it fit in the wheel hole and the drum/rotor....stick it in....hold the wheel thread the first bolt in and the next two...pull the handle BAM....yer there.

I have had the wheels off and on my cars more in 5 years than most people have over the life time of there cars. Never ever had a problem with wheels measing up threads. How does a soft cast aluminum wheel bend steel. Not possible. You won't ever wear the stud out.

My A6 has lug bolts too. They're a bit harder to install than lug nuts although the lip on the hub helps center the tire. Then a knee to the bottom of the tire when mounting leaves both hands free.

technically, they are screws, not bolts. Bolts are always used with a nut, and screws are always threaded into a part, I think.

That is the difference between a screw and a bolt.

I hate the screws too and therefore, pressed in 911 studs when I did my brake rotors. Much better.
