Near Disaster

I agree the safety latch is a concern but more of concern is that the spinner is coming loose. I know I'm gonna catch holy $h!t for this but here is a pic of my passenger side front Vintage Wheel after about 100 miles. This is with right handed threads on the right side and tightens toward the front. As you can see from the picture, the safety wire indicates that the spinner has tightened more after driving. I have a loop in the safety wire that I monitor before each drive.

Wow Todd, your spinner looks like it sits way out at the end of the hub. My Vintage wheels don't look like that. Are yours unique in some way? Oh, and you have a knick in your rim.

Yup. Don't have a stiff Martini and then mess with your spinners. Both fronts have the same material of the hub sticking out. The rears have a bit more. Your car is gorgeous. Not many cars I've seen that look good in 17s but yours is sharp. Been thinking of getting some spares like yours.

Thanks Todd. Those are Complete Custom Wheel (CCW) but of course I had to get rid of them when I went to the Vintage KO's. If the cobra was going to see any more track time I would probably get a set of 17" Vintage knock offs. But since I got the Panoz the cobra has been relegated to wax duty and official 4-wheel Harley duty...

Unless I'm having a complete brain failure, that doesn't sound right. On the passenger (right) side, you should have a left-hand thread that tightens anti-clockwise, surely i.e. they tighten against the normal wheel rotation.

And that's where the controversy lies. These are right handed threads on the passenger side which would tighten with normal wheel rotation. The wire indicates that the spinner has done just that... tightened. The conventional method is opposite from what I have but nobody seems to understand why it should be any particular way other than its just the way its been done over the years. I'm starting to think the spinners where tightened towards the rear so they didn't tighten so much that they couldn't get them off in the pits during racing?

Murphy,

We are out of wing nuts and immediately scheduled them back into production when I found out about this. We are just getting them finished today. I should have called and told you. My apologies. They will ship today or tomorrow at the latest! Thanks for your patience and being a great customer!

David

David, I will say it again. Buying your car was the best high ticket item I have ever purchased. Would do it again for sure.

TButtrick,
Sorry to jump in here, but before someone gets hurt, I have to totally disagree with your unconventional method. The correct and only way is RIGHT HAND THREAD ON THE LEFT SIDE and LEFT HAND THREAD ON THE RIGHT SIDE.

Now, I'll try to explain why. At least I'll try to keep it simple without getting into the engineering stuff that I wouldn't understand anyway

Here is an example of the concept I found.

Stand a roll of racers tape on edge, place a very large wrench socket inside of the tape roll, and proceed to to roll this assembly along a table top. With gravity the socket remains in the bottom of the tape roll, and as both parts roll along together the smaller part inside will rotate faster because of the
smaller diameter.

The corresponding parts on the car are the wheel hub and the large threaded nut. As the car rolls forward both parts are rotating in the forward direction, but the hub will turn slightly faster than the nut, so relatively speaking, the nut on the left side of the car turns clockwise in relation to the wheel as you drive forward, and the nut on the right side turns anti-clockwise, in relation to the wheel. Read the last sentence twice. The nut is turning the opposite way of the hub because the hup is turning faster. Get it?

To make these parts self tightening the threads must be right handed threads on the left side of the car and left handed threads on the right side of the car.

Did I convey my thoughts OK?

Of course if you are towing the car from the rear end, everything is reversed

I'll go take a nap now
