View Full Version : "Tuner Nuts?" Salted Or Unsalted?

07-03-2005, 06:21 PM
This got lost in another thread. I think it's a good question, but if it's a dumb one, I'll take the "guy who asks dumb questions award." :ugh:
For those of us who are new to the aftermarket wheels game, could someone explain the following highlighted terms?

"Please Note: These wheels require tuner style nuts/bolts and socket lug nuts/bolts for installation. We offer an installation kit that contains nuts/bolts, hub rings and valve stems."
I'll add one more question about offset: Is there an optimal (clearance vs. performance) aftermarket wheel offset (or OEM GEN6 wheel offset) for use on GEN5's. I know that there are wheel space diffs between GTs and GTs, for example, which will change what is "optimal."

I think that laying out these criteria would be of great help to those of us lurking around eBay, waiting for the perfect wheels to go on sale.

Not a clue what "tuner style" lug nuts are....probably some renamed ricer crap.
Socket lug nuts would be your average every car on the road nuts that hold the wheel on. Go look at your car. That's what they are. I guess you could use bolts instead of a stud and a nut, but I've never seen it [doesn't mean it doesn't exist]
Hub ring is a hub centric. It goes in the center of the wheel [inside the lug hole ring] and helps to center the wheel on the hub.

Offset is the difference between where the actual centerline of the wheel is [imagine slicing it down the middle, top to bottom] and where the actual mounting point is [ie the flat part that actually touches the brake rotor/drum].

These explain it pretty good.

Thanks Jeremy.

Tuner nuts, renamed or not, seem to be required for certain aftermarket wheels (that little, added-on cost the salesman forgets to mention). But what are they?

I knew what lug nuts are; I'm not that lame or wet-behind-the-ears (see my input under "how do you drive... thread).

Does anyone want to add more, or take a shot at my "optimal" questions? There's always a lot of what-not-to-put-on-your-car, but I'd like to see a concise writeup on "optimum" wheel/tire setups for GEN5s (and I know this is also driven by the intended use of the vehicle).

Here is my guess at what a "tuner nut" is, I believe it is the splined lug nuts that require a special socket to get on and off. I have seen this style used on wheels that have very small lug nut holes and standard lug nuts don't fit on the wheels.
That is my guess.

There are different kinds of lug nuts. 'Tuner Nuts' have a conical type seat, like regular lugnuts, they place the rim and center it over the studs. These lug nuts come in several styles, from the closed 'spline drive' shown above (I have them on my car) but those are meant for theft protection. They are also smaller in diameter to fit within the holes in the rims. Regular acorn nuts are the same as stock. Just fancier considering. There are open ended nuts used to show in racing that your wheel studs are long enough (most sancioning bodies require at minimum of 3/4" stud in your nuts.) Some racers will go with extra long studs so that they protrude to save hassle. Then there are Mag style lug nuts, also called shank. This are thicker lugnuts that go through the wheel, they are shaped for lack of better word like a penis. The shank is in the wheel and the wheel rests on that. The head of the nut is still outside the wheel and works like a regular lug nut to cinch the wheel down. These are normally used in Domestics.

Backspacing is the distance fron the inner seat (the part that touches the rotor/hub assembly) to the outer edge of the rim. Like a T. The easiest way to measure this is to remove the tire and lay a straight edge across the wheel. You then measure the distance from the seat face to teh straight edge. Too large of a backspace makes your tires/wheels hit the suspension and interefere with your turning (they will scrub.) Too small of a backspace will cause your tires to stick out and catch the fender. The proper amount will make your car look right. For Celicas (especially GT-S and GT4/Alltrac) you can get away with a smaller backspacing (means you don't have to use spacers) on the rear to even the lip of the tire with the edge of the car.

I hope this clears some of the confusion up.

When I think of "Tuner Nut" I think of colored nuts, or lightweight (aluminum) nuts.

I am run a set on my racing wheels:



Mine are open ended and they are extremely light, but fragile.

Whoa Mike!

I thought I was catching on here, but what the hell! Why are they so looong? What the purpose of that? I'd be afraid of taking out pedestrians who strayed too close to my car as I drove by!

They are so long becasue of the longer stud length. I posted about that above.

Actually, they don't look much longer than the stock lugs on a Alltrac/GTS.
And the MR2s wheels are similar [depth wise]

Sorry, but this is the first time I've seen this. I've read about stud length being important in racing, especially to the judges, but why that long?

What is the advantage of having studs that long that they require tuner nuts that are what, 6 inches long? Sorry for all the questions, but I try to learn something new every day. :)

Those nuts aren't even close to 6 inches. Not even 4.
They're probably like 2 1/2. If that.

The longer studs are so they don't break or shear off.

07-05-2005, 06:35 PM
lol, look what i started! okay, the lug nuts are long to accomodate longer wheel studs. racers use longer wheel studs because sometimes we run thick spacers for our wheels, and using stock-length studs doesn't give you enough threads to safely put lug nuts on.

yeah, the ones i have are about 2.25" long. that's my race setup-- i run regular "tuner nuts" (that's what the package said) on the streets-- they are just steel, closed-ended conical lug nuts that are blue, bought at autozone. :)

Woud you believe I meant 6 centimeters? I think that I got it now - the longer studs with standard length lug nuts would leave a lot of threads exposed to damage.
