fit wheel (note the ring (see pic of all the bits) fits between wheel and hub adaptor - has a spade connector that i didnt need, but it forms the mount and earth for the horn push - mount the ring so that its male spade is on the opposite side of the wheel to the one on the horn push otherwise they may foul each other)

Nice job Rich!

Good looking wheel that, I think I'll stick one on my xmas list!

Cheers,

Tim.

Great job Rich--good writeup too. I put a Momo wheel on my car and its funny how such a simple job can turn into a mess (in my case anyway--I drove around without a horn and no blinker shutoff for a week...so thats what those extra parts are for).

cheers, i think it makes the cabin more "business" like.

john, i know what you mean, i cannot believe they dont provide instruction - still thats the reason for the thread.

actually, maybe it is for safety reasons that they dont........

Thanks for the guide Rich! Just put it to good use over my lunch break:

Had to 'persuade' the hub to fit the steering wheel shaft a bit though! Did you have to as well?

Cheers,

Tim.

The steering wheel is on the wrong side of your car.

Rich,

Nice write-up. I have now been through this procedure a couple of times, and it gets easier each time. A couple more hints to go along with your article:

1) At the very beginning, remove the horn relay to better maintain the sanity of both you and your neighbors during the job.
2) Final step: Pry (or prise, if in the UK) the speedo out of the dash and rotate it such that "your" useful range of the dial is not underneath the (smaller) steering wheel rim.

Done and done!

Tom

Don't forget that some us prefer to (also) use the small spacer, besides the hub adaptor. It moves the wheel further back towards you, but (more importantly perhaps) it maintains the stock wheel's "eccentricity" ( by mounting the wheel higher, when in the straight-ahead position). This gives a bit more visual room for the instruments.

Good write-up, Rich!

When I did mine (late at night at Matt Holcomb's place), when we installed the horn button, even with the ignition off, we woke up the neighbourhood with rampant "toot"-ing as it clipped into place. :)

It's amazing the transformation a good Momo makes. If I knew it was going to be as good as it is, I would have done it three years ago.

Nice!

Coupla questions:
Who sells the Porsche badge for the horn button, and what were the really early (911R etc) boss's like? Did they still have the concertina plastic sheath over them, or were they (I suspect) solid?

Thanks!

Had to bang on mine a bit to to get it all the way down on the shaft. (Wait a minute, that didn't sound write!!)

i'm a bit behind here!

so *edit* TIM, you finally got your wish - looks great. no banging required btw - must be an "SC" issue ;)

matt, the horn push are quite readily available at suppliers - can't remember where i got mine - i think it was the wheel supplier. i have seen them on ebay as well. if you get stuck let me know and i'll try and dig out the invoice.

now that i've been using the wheel i can say that although it is heavier to use i love it.

thanks guys.

Blimey a bit behind, you aint joking!

Still asleep as well apparently, the name's Tim not Chris!! ;)

Cheers,

Tim.

TIM!!!

sorry about that - i sold some wheels on ebay and a bloke called Chris just came to pick them up! Thats the only excuse i've got.

It must be nice to see more of your instruments! Where did you hide the air bag, under the horn button?;) Nice Job.
