I have the snap off hub. There are 3 dowels on the face that slide into corresponding holes in the back of the "hub" much the same way a pressure plate aligns to a flywheel. The 2 pins then secure the 2 pieces together. If the 2 retaining pins fail then just keep the hub pushed forward and it will ride on the 3 dowel pins. This is the same hub used on some factory Lambo race car and also Lotus Exige Cup factory race cars. The use by OEMs of that stature kind of sold me. The only issue I have found is the use of the hub on very cold days there is a very small bit of play due to the dowels being steel and the hub being aluminum. I have the street version of it and was able to use a common horn push with the contact bent out a little and the horn works as well. I also "lubed" the retaining pins with key cylinder graphite dry lube and it works incredibly smooth.
all,
Word of warning on those ebay wheels. They are generally made from steel. the spokes have a tendency to snap off. causing a knife like object in a crash. The guys at mazmart can vouch. one of their employees was in a wreck. the ebay nardi knockoff wheel broke and stabbed him twice. He lost a lot of blood. i want to say 2 qt's, but don't quote me on the exact amount. he did almost die but they where able to get him to the hospital fast enough.
Aluminum wheel is a safer option as they will bend out of the way. Aluminum wheels are the only ones we carry because of that reason.
Danny George shared this on fb. Thought it was funny and on topic.

Correct. Typically steel will bend into a pretzel without breaking but most aluminum will crack and/or tear at the bend. Some aluminum alloys are much better at this than others. The problem I normally have with ebay wheels is that it feels like there is no metal core in the rim of the wheel, that its solely the injection molded foam rubber with no metal core like the name brand wheels. I've never cut one up to see, but I have folded one in half (by accident) and had it spring back to shape before.

A good indicator of that is ductility. The property to look for is the % elongation, or elongation before break. This will be expressed as a %.
Steel and aluminum both have alloys that are very ductile, or quite brittle, so a blanket statement that steel will bend more before breaking isn't exactly accurate. Kinda like 10psi ≠ 10psi when comparing different turbos. For example, 1050-O aluminum will elongate about 40% before breaking, most steels will be below half that number.
The eBay wheels are probably some ultra-cheap steel with nonuniform properties, and probably has porosity or is full of contaminates.

In reality, tensile strength is not an indicator of how much something bends before it breaks.

Want to know for sure, bust out the geiger counter. The cheapest of the cheap china steel will sometimes have some radioactive medical waste mixed in. Steel mills have geiger counters in their receiving offices for a reason. (For sure as in, if it is noticeably radioactive its the cheapest of the cheap, not being radioactive doesnt vindicate.)

Ok, onto the next item for spring. I need to get rid of my 91' air bag of death and swap out wheels. Does anyone here own, or have hands on experiance with the Momo Nero? I would love an all Alcantara wheel, but I know it will just turn to crap after a summer of use so I am trying to stick with something mostly leather.

Call our warehouse. we have those in stock, and can aswer your questions. If your worried about quality you don't need to. Momo has very good quality or we wouldn't sell them. this wheel will give you a long service life.

Yeah no worries about that. I already spoke to you about this wheel. Just seeing if anyone else has actually run it in their Miata or had used a Nero before. There is actually very little in any forum about this wheel. I did some google searching this weekend and didn't come up with much besides, "looks nice".

ofspunk7 those are straight rice.
My setup. Momo Competition, Works Bell Hub, NRG 2.5 QR. I like the perforated leather for a dual use car and this wheel has a very thick rim which I also like. Combined with A* tech 1zx gloves the grip is excellent and the perforated leather helps with sweaty hands in socal heat on the street.
Once the car goes trailer queen i'll get a momo mod 78

Why doesn't anyone use a Grant QR and wheel? I get that Grant makes some low quality stuff, but their price is pretty competitive and some of their more expensive wheels look to be decent quality.

Right at $230 doesn't seem crazy for this setup.

I currently have this Grant wheel in my car, and my only complaint is that at 5* of caster it is a bit small for autocross. I don't know anything about their 3 bolt wheels, but this one was substantially lighter than the stock wheel and is fairly robust in build. The grip material doesn't do well with sweaty palms though.

I would have thought a splined QR would provide a very solid connection with the steering column and the QR. I have been in a car with an NRG 2.0 and that thing had about a 1/4 inch side to side play in the wheel. It completely ruined the steering feel for me and didn't exactly inspire confidence.

Depends on the brand. the sparco, Momo, and woodward splineed QR are very tight.
the Longacre, Joes's and anything from speedway motors does suck.
