yes you can do this to your street car, you know those lowriders you see with gold spoked rims.... they use the knockoff hub setup.
I.E. a single lug in the center. why do they call it a knockoff hub... I don't know....
but... I don't know, i heard they are not allowed but the first generation of the ferrari testarossa, not the 250, had them too and the bb's also. i'm confused.
It's not street legal anywhere in America. The ones you see here are fake, with a cover over the regular lugs.
They are called "knockoff hubs" because originally they didn't have real hex for a big wrench; they had little wings sticking out that you whacked with a sledgehammer to spin them off for fast wheel changes.
Yes you have, you just didn't know it.
A lot of old british car's have knock off's. In particular MG's and Trimuphs. But you must adhere to a strict tire rotation schedule. One of the main problems in MG's and Triumphs is the Spinner becoming "frozen" on the hub. The fix requires the spinner be cut off with a torch. That also ruins the hub and the wheel.
America's sweetheart, the Corvette, has knock off's available from '63-'67. In fact, it's considered one of the more "revered" options. A set of original Corvette knock-offs can run upwards of $2,000.
I wouldn't want to drive one, especially at speed. But even now some race-cars use a "One lug" wheel to facilitate faster tire changes. I personally want at least 4 bolts holding each of my wheels on.
Most of the "single-lug" wheels you see on the street are usually a "cap" covering the actual lugs on the wheel.
You can't see the "line" on the cap from more than abou 5 feet away, and then only if you aren't at an angle to the wheel. Next time you see one of these wheel try to get a little closer, and you'll be able to see that it's a cap.
The cap on my Escort GT is almost invisible as a cap until you're inches away.
One time I saw this ricer with only one wheel nut. By that, I mean he had a normal 5 nut rim, and it was only held on by one nut. It was one of those locking security nuts. I ges numbnuts (pun intended) thought that cause you only get 4 in a pack, you onl yneed to put one on each wheel.
