Mr. Stock

Please post your experience with quick release steering hub.

I am thinking of getting a Sparco one but I know there are many different ones out there.

I am interested in the price including any welding required, how difficult it is to install, and how much play it has.

Thanks.

For starters, I would highly recommend a splined type coupler as opposed to the cheaper hex type. The splined units are generally better quality, and getting the wheel on and off is smooth and easy. Also they typically have zero play in them, which I can't say for all of the hex versions. Here's a good pic:

Secondly, these couplers are usually a stock car style 3 hole unit, so you will need an adapter. Smart Racing products sells them for less than $40 I think (I don't have the link right now). Between the two, you still come out ahead big time dollar-wise.

Mr. Stock

Your URL did not lead to a picture but is this what you are referring to?

Mr. Stock

Sparco one has a splined coupler.

That's the one I use.

Requires welding onto the steering shaft, but I have no issues with it, it's solid and doesn't wiggle.

Sorry about the dead link, it was a Sweet Products splined coupler that I was trying to point you to. Either way, the Sweet, Longacre, or Allstar units are all good pieces to use.

Yes, Sparco does have a splined coupler, but have you ever priced that thing?

It's out of this world.

The adapter I was referring to will let you bolt your 6-bolt Sparco/Momo wheel to a standard 3-bolt coupler. This way you save a ton on the coupler and end up saving big money in the long run.

The coupler adapter is not on their website, but I have emailed Craig and he confirmed they do sell it. The link is:

my dads car has the momo one. fortunately, he never had to exit the car as fast as possible, but ive sat in it and tried and its very easy. no play either.

I don't actually own one but did consider one for a while. The fact that they use these in Lamborghini Supertrophy cars is pretty inspiring.

Their steering wheels are quite nice too.

I have used a Wilwood hex style for 3 years and have had no troubles. I modded the hub to be a bolt on fit. No welding required. This is good in case you need to relocate it to a different car. And also if you weld it a little off, the weld on ones leave your steering wheel permanetly cocked. If theres sufficient demand I can make them up for whoever is interested.

Smart Racing Products sells a non-welding required quick release hub. THis hub screws to the adapter from your wheel manufactuer, and then the smart racing products hub attaches to the wheel. If you have questions, Leslie at their office in Campbell, CA can help you.

Hope thats helpful

Rx7carl

Yea but thats $220, and you still need the shaft adapter. And it only fits 6 bolt momo, sparco etc wheels. Mine fits the standard 3 bolt style, and is ALOT cheaper.

stockrx7

sure yours is the best

TeamWireRacing

Carl,

The Wilwood is a lot cheaper if you are using a 3-hole steering wheel. Actually, I would still use a different one than the Wilwood (D&M) because I prefer the 360 degree release type, and the Wilwood is the pin type.

Mr. Stock had made reference to a Sparco wheel in his initial post, so the only way I know of connecting a 6-hole steering wheel to a 3-hole hub is an adapter. Or you could pony up the $200 for a Sparco hub.

The Smart Racing adapter is a round piece of aluminum that has the 3-hole pattern in the center with the 6-hole pattern drilled on the perimeter. The center bolts are countersunk so you can lay the steering wheel over the top of them and install the bolts for the wheel. It makes for a tidy installation and it works well. And waaaayyyy cheaper than 200 bucks!

The Smart Racing Quick Release hub is 219 dollars. THe adapter that actually mounts to the steering column from Sparco, Momo or QMP is appx 69 dollars, and well.. you all know how much racing wheels are. This is all you need to create a quick release system. Yeah its expensive.. but hwne you flip over 3 times and your ride is on fire.. i think you want a quick.. easy way to get your wheel off so you can get out of your ride
my 2cents

TeamWireRacing

I agree fully with the safety aspect of the quick release. My point was only to show that by doing a bit of research, it is easy to build your own setup without having to pay top dollar. In this case, buy using a stock car type 3-hole coupler and mating it to the Smart adapter, you can save yourself about $100. No difference in safety, it's simply being a wise consumer.

Rx7carl

Well I guess mfg these things sounds like a losing proposition LOL. Oh,well. Chris you gonna be at RRR next week?

TeamWireRacing

Actually, I think if you could get your costs in the $20-$25 range per unit, you would be okay. It may require that you do them in lots of 100 or more to get the machine work costs down. Most racers would gladly pay $35-$40 I think to be able to use a nicer wheel without having to resort to spending $200 for the quick release.

No, originally I was scheduled to go with a guy who works for me, but his transmission blew up at the Turkey Trot at Sebring and then his back went out on him, so any thoughts of yanking that tranny and repairing it for the school was gone. I did see that you are planning to attend though. That's great! Take heed of all the advice on IT.com because it's good stuff. Keep your nose clean, watch the flags, and have fun. Then come race with us at Daytona in May!

Good luck up there.

Rx7carl

Well Im definately hoping to keep the cost under $100. How far under that depends on what my machinist says.

Does anyone know of a quick-release that works with the stock steering wheel?

slinges

Anybody? How many bolts does the stock wheel have? I haven't looked at it...

The stock wheel uses a single nut. The end of the shaft has a spline and thread on top of that. The wheel slides on the splines and then the nut is tightened over the wheel. I can't think of any type of release that would work with a stock type wheel.

I know on a 1st gen, if you wanna use the stock wheel you have to remove the stock adapter. The you could drill it to fit onto a QD.

PS- My 1st gen QD should fit all 7's. IIRC the splines are all the same.

Couldn't a spline type adapter that fits onto the stock steerting shaft splines be manufactured? You would probably have to machine a groove in the shaft for the locking mechanism to grab though.

Rx7carl

Yes it would have to be bored, tapered and broached. Im waiting for my machinist to get back to me.

how many spline does the 2nd gen steering shaft has? Any company made a adaptor for it yet? Wonder if the 3rd gen have the same number of spline and dimension? Anyone know the answer?
I am thinking about getting a QR set up for my FC soon, my focus is on zero play and cheap. Help please!
