Replacement Steering Wheel Questions

Capt Nobody · #1 (**permalink**) 04-09-2023, 12:11 AM

I have a 2022 SPF MKIII-R.

The 'R' model comes with a 14.5" leather-wrapped wheel instead of the wooden steering wheel.
The steering wheel Superformance chose is an absolute deathtrap! The wheel spokes are made of very cheap aluminum. To the point where if you hit the brakes for a sudden stop - the steering wheel spokes bend significantly towards the dash. Not the entire steering column - just the part of the wheel you have your hands on!

I am upgrading to a Momo Eagle steering wheel. I would prefer not to drill new bolt holes in the wheel itself - there is no way to cover the bolts on that model Momo wheel.
I am looking for advice on proper Hub Adapter replacement and how to properly do the install.

Thanks!

Here's a good start. https://www.finishlineaccessories.co...ng-wheels.aspx

Thank you for the input Nova. That page offers zero help.

I am installing a Momo steering wheel on a MKIII. I'm looking for someone who has experience with this installation - including which hub adapter is best, and what pitfalls to look out for during the installation.

@ Capt Nobody, the search engine here, is your best friend, I'm sure that question has been asked before, if not SCOF web site will have your answer. If your Superformance has a VW Bug turn signal stock (like in the picture), that's the (Boss) hub kit you need, the steering shaft spline is VW. VW Bug to 6-hole Momo adapter. Hope this helps. Cheers Tom.

That is not a hub adapter it is only a top ring. It will do you no good. Equally important is the fact that, if you buy from Finishline, you run an extremely high risk of them taking your money and never sending you the parts you ordered.

The only firm today that I am aware of which offers steering wheels for the original bolt pattern, that SPF uses, is the original Steering Wheel Manufacturer, Moto-Lita. This is the link to their site and their Cobra Steering Wheels => https://www.moto-lita.co.uk/steering-wheels/?filters=639

Jim, this is mine and is held on with just 1 large nut in the center.

Of course, my SPF is 23 years older than yours.
I do still have the VW Bug turn signal ring and arm, my 3rd one.

hmmm - didn't think I'd need to point out you can scroll down a page to peruse other things that may be there...try again. https://www.finishlineaccessories.co...er-6-bolt.aspx It's just an option. And it seems to me this isn't the first time you've asked for help - then shot down a response. No need to be rude. My suggestion is more in line with - you got the wrong steering wheel. Don't try to reinvent it - literally. No need tom modify anything to accept the wheel you have - get the right one instead. Return what you got and start over. There are many other steering wheel options out there.
And yes - Taylor has his challenges running the Finishline site and it can be frustrating, but he does respond and does in the end deliver. Patience is a virtue. So I'll take exception to other comments. But you can get the wheels elsewhere. I'll also add here the SCOF site mentioned above. Though do tread nicely. https://superformance.org/scof/

And you might as well put a Quick Release hub on your Moto-Lita. It will make your life easier in a number of ways.

23 years older... :-)

I saw a red(?) SPF at Sebring in 1995 or 1996. I looked at it and commented: Oh, knock-off wheels! Must have been a very early one, for the US.

Steering wheel:
I mounted quite a few 15" and 16" on original hubs. Now to get a bit close to an answer to this topic I (we?) need to know if SPF also has the odd non- 6x60° bolt pattern like the originals have.

Pic shows original pattern.

That is a weird pattern

Why would they do that?

Cheers!

That 6-hole bolt pattern is actually the Nardi bolt pattern. Momo may (Unknown to me) use it now too. I was lucky enough the buy a NOS 6-bolt Nardi (Thanks My427 "Greg") Had a one-off adapter made from a 5-bolt Grant to fit the new 6-bolt Nardi. I would think Glen, so you have to buy their adapter

Over the years, different dimensions on these cars tend to 'evolve'. Sometimes that is because of drawings being made from hand-made measurements of a part, and yet other times from modifying components to accommodate the different design of an evolved newer mating component.

The PCD (Pitch Circle Diameter) dimensions which Dominik shared, as he indicated, are accurate for an original CSX car from AC and, I believe, also a CSX continuation car from Shelby.

The drawing below is the PCD that Superformance uses for its steering hubs. The bolt holes of the two drawings are offset by 90˚, so you need to rotate the SPF drawing 90˚ clockwise to get the same fastener orientation as in the CSX drawing.

When you rotate the SPF drawing to mirror the CSX drawing you will see the dimensions are 'essentially' the same but still different. Remember my comment about 'evolving' dimensions.

Which is historically correct is less important than which will fit your car! You have an SPF car so your bolt pattern is the one I have included in this post. If you use the fastener locations in the SPF drawing, you can rotate the hub orientation to optimize it for the placement of your new fastener locations.

The SPF hub uses a VW steering hub spline that has 31 splines so you have the ability to make minor adjustments to the hub clocking in 11.6˚ increments (a single spline offset) to regain proper steering wheel alignment for driving down the highway.

If the new wheel you want to use has a bolt pattern that will not allow you to modify your existing SPF hub, then you need to make a new hub and essentially start from scratch. The necessary dimensions are in the print above to allow you to do this. When you do, remember to re-spline the new hub for a standard 31-spline VW steering column, which is what is in your car right now.

The fix you are looking for is not that difficult, but again, it is not a walk in the park. That said, you now have all the information you need to solve the puzzle.
