jimmybondi Hi,

I would also be interested in the Evora wheel hub for my '96 S4s

Thanks.

flopshotgolf Just purchased my first Lotus, a 1997 Esprit V8, and replacing the steering wheel I saw one of the first things I want to do. Iíll search the forum for instructions oh how to do the replacement. Do you have any more of these Evora hubs? Please let me know! Thanks.

JRSMagic Hi I’m new to the forum , and I was looking at doing a swap of my stock 94 S4 steering wheel for the new Evora one, are you still producing these would love to get one, also is it relatively easy to do the swap? Thanks

Alex/Rob,

I'm looking for one too. Could you let me know if you find that it's still an active option?

Thanks

RickN This looks awesome! Where did you source the wheel with the blanks and what was the cost?

duneomatic I donít make the adaptor kits to make money. I do it to support the great members on this forum. If I never made another one I would be happy, but people keep asking me to make them. My time is very valuable to me and I have better things to do then make adaptor kits for people that think it is just a piece of aluminum. I will continue to support this community as long as it is appreciated and based on the feedback I get it is. Thank you all for the positive support this community has given me over the years.

Wrong again, my adapters were made on a cnc machine and still required the broach to make the splines. That's how splines are made on a cnc machine, with a cutter called a broach...

You can buy a broach for a few hundred bucks in a standard spline configuration but if you need a custom one made for non-standard application as in the Esprit steering column, you have to pay several times more to have the tool made.

A truer statement has never been written Constructive criticism helps us all, criticism for the sake of of it helps no one. Roboto does though admit to having a small brain and being a cheapskate so if nothing else he does self deprecate and that is a good thing

mieczkow Well, let's say we spend $300,000 for a state of the art CNC machines capable of doing the entire machining protocol for the adapter. Not counting software costs, programming costs, billet costs, and actual production labor, how many of these adapters do I need to sell to "turn a profit"? More than I could ever possibly sell to Lotus owners.....

My point is that there have been a number of owner-initiated tool projects, some very sophisticated like Jim's and some very simple like my water pump seal tool. NONE of these are based on the idea of profit. The blood, sweat, and tears are dedicated to preserving the Esprit. Check out the extraordinary stuff Mr. Dangerus has done, including transmission fabrication. Astounding amount of work.

Nobody is in this for the money. Owning a Lotus is from an economic point of view totally irrational.

Roboto Esprit I did want to say it is a nice piece. Like I poked at in the last post the price is near the ballpark for a few spun off by a guy in his shed due to things like tooling and set up time ect ect. The returns arent massive. A big seller can afford to sell this stuff much cheaper even at the stunning quality you have here. Why? Because a new cnc can knock this out so fast without the need for making the tooling. By the way that tool you have pictured is sweet. I dont know much when it comes to machining but I know enough to agree after reading what ghalliger posted.

mieczkow Hey Jim,

Well said! 😉

lotus4s Ahhhhhhh Mr. Roboto, you know so much to know so little...

Back in 2003 I procured engineering and arranged to have adapters fabricated for the Raid airbag wheels to fit our Esprits by one of the largest state of the art manufacturing facilities in the Southeast. Over the years we had several group buys and over 200 were sold. Although I wouldn't profess to be an expert, I do know a little bit about the subject.

In an effort to possibly enlighten your "tiny brain" as you say, here are pics of the required broach and the original prototype. The adapters for the Elise/Evora wheel are similar but different enough that my adapter won't work with them but the tapered splines are the same. As you can see, it's a high quality piece and I'm sure Duneomatic's Evora adapter is comparable.

Just to be clear, there are probably talented machinists out there who could cut the splines by hand, but it's not something you'd be able to "throw him a bone" and he could whip out in an hour. A one-off would be quite expensive.

Roboto Esprit Well. I did not know it was a forum member making this in his shop. Go fourth and machine to your hearts content. I was under the impression this was u know... Double mark up usual esprit nonsense. But anyone with a lathe or mill can do the spline cut. The same mentality I take here is the same I take on any forum. If a guy in his shop is cutting out a decent hub and of course your going to see it and wants to charge that price for a mark up. He aint turning into a millionaire and I imagine cutting a few out at a time theres set up time getting the tooling right ect. But... Where are the pictures??? Lets see the hub... Erm adapter.

^ It says I take it back. but wish to see photos.^

S4Denver... Nice... But you did poke the bear... Not so much the joke but the KNN. Thats a whole thread of guys losing their S###. You want to know what I think about KNN and why PM me. Every time I hear about their drop in filters I cringe.

S4Denver this could get interesting... should I poke the bear?? I guess I could have taken an old T-shirt soaked it in oil, could have saved $ instead of my K&N

IF your a cheapskate like me theres aways option three. Cut out an existing wheel center make a jig and weld up an adapter plate.

Where are you at that it cost 1200 bucks for a broach job.

Pissing down your boots I am not. I just cant wrap my tiny brain around these prices. I could see paying it for a tranny adapter plate yeah the machining is simpler but the math isnt and the size of the billet is larger.

BTW the person who has the adapter please post up. Is it billet or cast or... Steel..

Gallagher I think you've explained it to yourself here...most members are not interested in hack jobs to make things like this work, and would much rather support a forum member that is likely making little to nothing on these parts that will provide a superior installation. A properly installed Evora or Elise wheel with a nicely machined hub adapter will likely increase car value, or at least increase the saleability, whereas an adapter made from an old wheel with the center cut out and a mashed up adapter plate would likely decrease value and saleability in addition to causing a lot of people to just walk away.

FYI: The hub adapters are visible after installation (at least the Raid adapter is on mine).
