There has been some debate on the importance or otherwise of the
existence of a lip/spigot on hub adapters. I am talking about a lip/spigot that is a neat fit inside the hole in the centre of the rim. I have had at least one new thought on this and offer the following, in order of increasing importance; - during fitment of the wheel a deep lip/spigot takes the weight of the wheel while you locate the studs in the holes, making it easier. Then a lip/spigot of any depth makes locating the nut tapers into the rims easier as well. - if the wheel nuts come loose a lip/spigot will keep things together for longer, possibly providing a safety and economic advantage. - a lip/spigot provides immense backup strength if the studs and the friction between the hub and the rim are overloaded. During overloading the studs would flex and the friction would be overcome, but rather than the studs permanently bending or breaking and the wheel shifting significantly or letting go, the wheel would only move a fraction then the lip/spigot would stop any further movement. The studs may then cause a re-adjustment back towards the original position. Regardless, friction would be reasserted and all would be well, even the balance.

i didn't like the skinny a** one that came on my hub adapters. got a mates dad to improve them for me.

they're a press fit into the hub adapters, and a perfect fit into the wheels. The originals do look thin, at least a bit thicker would have been better. It looks like you wouldn't be able to fit standard wheels anymore though? [PS i have a 14" screen and your photos are BIG, it's great for detail, but in this case smaller might be better?]

No standard wheels will fit on most hub adapters with a lip. reason is because the lip goes outwards, meaning that the centre hole in the back of the wheels would have to be larger. this could be changed easy enough but. that second picture is deceving, the centre peices actually go inwards. |

I wasn't sure but i figured the standard centre tapers, so once the adapters are over say one inch, i figured they would machine out the centre of the adapter while leaving a lip. Hmm. Another point, not mentioned in my opening ideas but relevant to the third point, is will the studs break without a lip anyway? Maybe another part of the suspension would fail before the studs fail. Maybe in a horizontal load the front radius rod washer would be extruded through the chassis? And maybe in a vertical load the strut bottom flanges would crumple and/or the bolt shear? - the load there would be magnified and the two shear points would be less area than the five studs. Quote: that second picture is deceving, the centre peices actually go
inwards. I thought i was going okay but now i'm confused. Did the original lip get machined off?

I think now it's just your comment i don't get. It looks to me like the hub adapter wasn't snug on the hub centre, and the insert is, meaning the insert in that section would be a few mm thick all the way along (concentric). The outer part, the lip, is possibly say 10mm thick. Towards the outermost part of the insert it has a radius before it meets the hub. ? Today i looked at my EBII front hubs and the locater/bearing housing seems about 50mm long and is not tapered, so i can see that a lip is not possible or needed here with std wheels.

Here's a picture after some jack prick has stolen one of the center caps from my Simmons - you can see the new centre lip there:

Were the simmons custom made, machined out, or standard? If standard,
why do they make them with a bigger centre that wouldn't be right for most people?

These ones were on an AU previously I think. I had the centers machined out a bit to fit on the hub adapters.

Did you consider modifying the adapters in such a way that the rims
could stay stock? That would seem easy to do, there would just need to be a step in the inside diameter of the adaptation.

THat would have to have been done when the adapters were first made - can't be done afterwards, as the metal has already been taken off. Either way didn't overly bother me as both ways the wheels and adapters fit fine on the car - I'm not looking at changing wheels any time soon - but I have been thinking about redoing the back simmons so that they're wider and don't need the adapters, leave the fronts as are then when I get a brake upgrade the changed offset won't matter. I can always get some rings to fit in the back of the wheels to fill in whats been removed. |

THat would have to have been done when the adapters were first made - can't be done afterwards, as the metal has already been taken off. I don't think it's worth debating, but i was thinking you had added material during your modifications to the adapter and could have accomodated my suggestion then, or could do so retrospectively. I was also thinking that in the original photo the unmodified adapter actually seems to have a larger I.D. than the O.D. of the axle bearing cap, which would give a tad more meat to my suggestion, but i knew that could easily be a viewing trick. Ultimately of course you can actually do pretty much anything with it if you have a lathe, welder, associated tools and materials, and sufficient expertise. I figure as a general rule where you have to modify one thing or another its better to modify the cheapest most readily available component. And yet all in all i can't say exactly what i would have done when faced with your situation because there are numerous peripheral factors i'm not aware of.

You are right, I did add the new peice in, but the back of the wheels had already been machined prior to that. There are alternative ways of doing it, and if I had the resources myself I quiet possibly would change it, but it's working fine as is. |

"twr7cx" can you not post pictures of that resolution and file size, even if you had some massive resolution you would have needed to scroll across the screen to read posts, there is also members stuck with dialup, you had almost 3mb of pictures posted (no I am definitely not on dialup  ).
