I have just brought a Momo steering wheel with a hub kit, my roadster is not airbagged, does anyone know how to take it off, does the center bit just pull out?? I had a look at the back, there is 3 bolts there, but I think they hold the wheel on!!! (12/99)

Before you start - line the steering up straight ahead.

The black plastic centre thingy will just pull off if you have an existing Momo wheel (as fitted to 'Special Package' Roadsters) - otherwise I think you need to unbolt/screw it. (If there are three bolts behind the spokes it's not a Momo wheel) If there's a horn button underneath, it will prise out (again definitely if it's a Momo wheel) Then you can undo the central nut which attaches the wheel to the steering column.

Remove the steering wheel - you'll probably need a puller or some ingenuity to rig up an extractor - the wheel is usually very tight and you MUST NOT hit it with a hammer.

Or, again if it's a Momo wheel already, just undo the six allen screws to detach the wheel from the Hub adaptor, and fit your new wheel. Then send your hub adaptor back for a refund, 'cos you don't need it.

If you have a non-Momo wheel at present, fit the new wheel to the hub adaptor (6 allen screws) then place the wheel in position on the steering column and tighten the nut to 29-36 ftlbs. Make sure it's on straight before tightening. (12/99)
Does a Nardi Mk2 steering wheel fit a Mk1? (3/00)

It will fit on, but without the airbag module, you will have a dirty great hole in the middle of it and you will be able to see the frame

If you buy the module it will look fine, but you won't have anything to fire it when you hit something. Also , you will have an explosive device in front of you, with it's electrical connections floating around - not a safe state of affairs

Better off spending the money on a nice Momo wheel and adaptor from Moss or someone similar. (3/00)
Look up the Miata list archives (www.realbig.com/miata); there's an amusing anecdote about the removal of the detonator from an airbag, and its subsequent "disposal" (take one battery, 25 ft of electrical cable, stand well away). I doubt shipping regulations will permit shipment of an "armed" airbag. I can't even send dry ice to England without a lot of paperwork. (3/00)
Having a look on the pics on your website, I saw that you still had the plastic/rubbery cover on the steering wheel, did you realise you can pull this off easily to reveal a rather more tasty (IMHO) momo badged steering wheel? (4/00)
And then replace the 6 bolts holding it to the boss with shiny chrome ones from Donutz (4/00)
My old leather steering wheel looks as though it has seen better days, and I have loads of Connolly leather left over from doing some DIY gaiters/seat belt sleeves/arm rest pad and so I thought about using this to get my steering wheel recovered. Any ideas where I would get this done and how much? And before we go down the thread of just getting a Momo etc., mine is an OEM airbag and I want to keep the air bag. (4/00)
It depends where you live. If you have the leather all you need is somebody local to fit it. I don't think the post office will be too keen on you posting an airbag (containing explosives) through the mail. Mike Satur (Bansley) does leather bits for MX-5s. He should be able to sort you out. Alternatively there is a company in Newcastle who advertise in STHT. (4/00)

I contacted Connolly leather in Ashford Kent, but they couldn't help with what I wanted which was basically 1 m2 of leather to match my BRG. They could dupply a hide (approx 4.2 m2) but this was going to cost about 180GBP. Anyway they put me onto a distributor guy who let me have a spare half hide for 40 quid cash up in Surrey. I think it is the Spruce Green used on Rolls Royce and looks great. Big thanks to my Mum for helping me machine tha gaiters etc.

Hakuna is a great guy and loves to do DIY jobs around the car. (4/00)
I'm getting tired of my crap standard steering wheel, any tips on replacement, I think a nice sporting leather one would do nicely! (5/00)
Have you checked out Momo, they've got some cool loooking wheels, with brushed metal finish centres...the Race model looks particularly nice, costs about 150 quid including boss... You can also buy an adaptor from a company called SVM which allows you to totally remove your steering wheel, excellent security device, it costs about 120 quid. (5/00)
I fitted the momo race (350mm) wheel and it looks very nice, wheel cost 120 from Burton performance and the boss was 25. The snap-off boss as suggested by Si Dewey is a good idea but after I eventually tracked one down I decided against as it brings your wheel soooooo far away from the indicator storks, you would have to remove your hand from the wheel each time you wished to signal or wipe! I would have also had no skin left on my knees by now getting in and out! (5/00)
Demon Tweeks also do one - Snap Off anti theft system - compatible with Momo, OMP or Sparco steering wheels 125 + 12.75 adaptor It's key operated too for additional security. Does anyone know whether it could thus be used with the original Momo wheels fitted to early MX-5's like mine? I'll also ask Demon Tweeks the same question. It must be considered a very good and relatively cheap anti-theft measure. (5/00)
Don't see why not. The Momo boss is the same, and so are the fixings (Allen bolts). If you buy a new Momo wheel, it fits straight onto the original boss. It looks like the anti theft ones add a bit of distance from the original boss though. (5/00)
Can anyone tell me how to remove the standard early Roadster MOMO wheel if I don't have access to a puller ? I hurt my hands last night trying to get the thing off ! (5/00)
Remove the allen bolts (6 I think) around the horn. (5/00)
Just undo the central nut and pull the steering wheel from left to right with force, it will come off! (5/00)
You can undo the nut a couple of turns then clout it with a suitable drift. Don't take the nut off & hit the threaded part underneath or you'll rivet it & never get the nut back on. Don't overdo it or you'll partially collapse the collapsible part of the steering column. While you're applying the hammer use your knees to exert lots of upward pressure on the wheel rim. This + penetrating oil (sounds like a sex aid) should pop the thing off - worked for me! (5/00)
I have a 1995 1.8 Eunos Roadster with a standard non airbag steering wheel . How easy is it to fit a Momo steering wheel and is there any problem with re-fitting the horn button to the centre of the new s/wheel ? (1/01)

Depends on which wheel you have. Many Roadsters have Momo wheels anyway (it was a special design to accommodate the nasty plastic centre insert) but some have Nardi's or anonymous plastic ones.

If you have a Momo, you just remove the six allen screws around the horn button (3mm allen key), take off the wheel and put the new one on. You don't need a new adaptor. I'm not sure if you can fit a Momo wheel to a Nardi adaptor (anyone?)

Otherwise you may need to undo the centre nut, extract the wheel with a steering wheel extractor (you may be lucky and be able to wiggle it off, or your steering wheel supplier may do it for you - but whatever you do don't hit the steering column with anything!)). Then fit the Momo adaptor and wheel - the horn button connection will just slip on and a Momo horn button will obviously go in the centre. (Roadsters with Momo wheels have Momo horn buttons anyway - sometimes a "second" (eg with bubbles in the plastic) 'cos you can't normally see it.)

NB Roadsters have airbag wheels from August 95 - then it's not so simple if you want to keep your airbag! (1/01)
I'm not sure if you can fit a Momo wheel to a Nardi adaptor (anyone?)
Nope, the Nardi is slightly off line compared to the Momo, it would go on, but would not be straight! (1/01)

I don't have a tape measure with me right now... ... does anyone know, either off the top of their head or has details somewhere, the diameter of the MkII airbagged steering wheel? Here's my reason: I've looked long and hard at the options for replacing the standard steering wheel. Trouble is, I have a Eunos Roadster with an airbag and I think I'd like to keep the airbag (I'm sure my insurance company will insist) but my steering wheel is pants. It doesn't "feel" like a sportscars steering wheel and it's plastic not nice leather... and finally it's too big. I'm 6'1" and I have trouble in lots of traffic as the foot pedals do not seem to be centered on the steering wheel so my left leg ends up bent at a funny angle.

Anyway, needless to say, a slightly small diameter but chunkier steering wheel would go down a treat. So, as I see it my options are... see if I can fit a MkII wheel which looks and feels better but not sure on the diameter or import a horrendously expensive wooden airbagged wheel I found from some page linked off miata.net and then try to bribe / con / whatever customs to let an explosive device into the country. Does anyone have any other ideas? (1/01)
I am pretty sure that a Mk11 steering wheel will not fit a Mk1. The Nardi is at a guess around 350mm. The other option could be to get a 4 spoke Momo airbagged wheel from a Mk1. It may not be much smaller but it will feel nicer. Again someone like Ka Yu (?) might be able to help, but you would have to buy the airbag and the wheel. On the insurance front I know that AON don't mind if you remove the airbag. (1/01)
I've just replaced my standard mk1 MOMO wheel with a MOMO Champion which is 350mm, the Champion is 1" smaller in diameter at least than the standard one which I guess is about 360-370 mm. (1/01)
Anybody put a Moto Lita on a 5? Europa stock a good range, in diameters including 350, 360, 370 etc, both dished and flat. I rather like the idea of a wood rimmed job with faired metal rivets in the rim, 3-spoke with lightening holes in the spokes. Hmm..... But would the boss fit a 5? (1/01)

The only thing to watch with the smaller steering wheel (I still have a leather/black alloy 320mm one kicking about) is that it obscures the top of the instruments .. so you cannot see 50-80mph plus rev counter .. plus oil gauge .. you may get away with a 350mm one..

Leg room .. hack foam out of base of seat .. and then tilt the base to support knees .. and tilt seat back more than you might. (1/01)

I went for a smaller wheel, a MOMO Corse, and I can't see the indicators, pain sometimes as mine are set wrong (due to bad new steering wheel fitment ) and sometimes stay on. :| Feels much less like driving a bus though. (1/01)
Are you suggesting that you could retrofit an air-bag equipped wheel to a Mk1 that doesn't currently have an airbag? How much work need to be done to link it into the cars systems? (1/01)
No. I have not heard of anyone retrofitting an airbag and I am even sure it could even be done. You can change airbags with associated steering wheels or remove an airbag and fit a Momo. (1/01)
I have the steering wheel not straight problem too. How do I get it straight? (7/01)

Easy-peasy to do it yourself. Either run the car up on ramps or jack it onto stands. Slacken the clips that retain the dust boots, and loosen the locknuts on the tie-rods. Rotate the tie-rods an EQUAL amount in opposite directions (they both have right handed threads) to correct the deviation. Start with about one 'flat' a side and then road test. (If you've worsened the problem, go back 2 flats and re-test). Each full turn of the tie-rod alters the toe-in/out by about 7mm, so make sure you alter it the same amount each side, assuming your geometry was right to start with.

This *can* be done with the car still on it's wheels, but it means winding on lock one way, then the other, to enable you to access the locknuts, so you need to be able to move the car backwards and forwards. (7/01)
But why bother when the garage will do it for free with a 4 wheel alignment :) (7/01)
