Stu,
From what I now understand about the thrust rings and alloy wheel only knock-on nuts I think you need to sort this out quickly. Without the thrust rings I can't believe that the knock on nut is actually forcing the wheel onto the hub. From your photo it appears that the thrust ring is in place. The wheel and the thrust ring have the same curvature in that area. There is an additional complication in that Minilite changed the thickness of the thrust ring at some point in time, probably to solve the problem of knock on nuts bottoming in the hub. The two versions are shown in the photo below which I have posted before. The thinner version does not work. In an earlier thread I remember some people saying that they had shortened their hubs in a lathe by turning material off of the threaded section. This allows the knock on nut to travel further and engage the wheel and thrust ring properly.

Is it a conical bevel to match the 'standard' Lotus bevel found on both the octagonal Nader Nuts and the three eared spinners? Bonus marks if you have a pic of the centre hole with the thrust rings in place. I am directing John to this thread in my follow-up email. I will mention your pic of the thrust rings.

They told John that talk of alloy vs. steel profiles is mistaken and that they are the same. I just don't know what to think now.
For reference, here are some pics of my Minilite thrust rings. Still a bit concerned that the outside profile of the provided thrust rings is a curved profile. Witness marks on my thrust rings and Nader Nut show a line of contact rather than the wider profile contact with my stock steel wheels.
Wondering if I should get the Minilite rings machined to a bevel corresponding to the Nader Nut?

Stu,
I have learned quite a bit since this thread started. It seems that Minilite has essentially copied the thrust ring and knock on nut configuration that Lotus used with the Brand Lotus wheels. Minilite can say what they want about there being only one nut configuration for road-going cars. This flies in the face of what is stated in the workshop manual and that there are nuts that are clearly marked for "alloy wheels only". It appears that both types of knock on nut have the same conical seating face which I don't think is a great idea with the resulting line contact with the thrust ring. There is not enough material in the Minilite thrust ring to generate much of a conical surface. Making new ones that are shaped much like the Panasport thrust ring might be a better approach.

I guess the other alternative is to find the illusive curved? profile alloy Spinner/Nader Nuts? Did someone send you pics or additionl info?
