Steering wheel fitment

[Elanlover]

Exactly what i was thinking, the OD of the adaptor on the six bolt wheel mounting side is 78mm, the od on the hub side is the same but has a step in it which is of no concern.

Well, there's a small problem with this adaptor then. The circular opening on the bottom of the Elise wheel is 87.5mm in diameter. So, an 87.5mm sized adaptor would be ideal to ensure it would drop in and line up perfectly. Otherwise, it will be difficult (but not impossible) to center the adaptor. However, the Elise mounting hole pattern appears to be an 80mm circle which is 2mm larger than the diameter of the adaptor. Figures. The adaptor i have (for Momo but not made by Momo - aftermarket instead) has a diameter of 85mm. But, that's just a flange on top of the body. The main body has a diameter of only 65mm so it won't work either.

Back to custom again unless another adaptor can be found that can be modified.

I'm not entirely clear on the relationship of the pieces because I don't have an Elise wheel and I've never had the stock wheel off, but it should be pretty straightforward to design a suitable adapter, and I'm sure I could have them made for a reasonable amount (I would consider the $200 price on the other adapter to be the upper limit of reasonable). I've sourced much more complicated parts on mfg.com, and it's always surprising how cheap people are willing to go, especially now, even in low quantities. There's no reason to be overly concerned about trying to modify some existing, hard to find part.

This is what I do, although it would be difficult for me to do much without having the parts in hand.

I know very little about the costs associated with low run, custom made pieces so what you say could be very true. But, the piece is a bit complicated with all the cut outs, etc. Here's a pic of the piece in question. I'm all for paying less

superbad - I've got two Elise wheels... so you can feel free to take over this project and buy my 2nd wheel for your own car

As parts go, that's a simple piece. The internal splines make it a little tricky, but it's still not that bad. I would be happy to take this on, on a time-available basis.

Please feel free. I am also pursuing a second, custom made option for a small run of between 5 and 8 at a local waterjet cutting shop. The more options we can consider the better. Let me know if you need any help.

Not sure if you're trying to do the whole piece that way, but waterjet can't hold sufficient tolerances for the splines. It makes a very conical cut on a thick piece. Anyway, to get started I would need both wheels, including the turn signal ring or anything else that needs to attach. I can't take my car off the road for more than a day or two, so using my own is out. Alternatively, if someone else has drawings (even relatively rough drawings that I can detail myself), I can get some quotes.

I think they'll put the billet on a lathe to get the shape, waterjet cut the large openings and send it out for the splines (as they implied to me).
