Unhappy concerned - 2nd guessing my purchase of Muteki Super Tuner Lug nuts; 85ft-lb max TQ

so I recently picked up a set of (black) Muteki Super Tuner (spline) Lug Nuts. There was nothing on the seller's/vendor's webpage about the torque specs.

I just figured the Mutekis would be the same as the OE, or it didn't matter, as they are steel, like the factory chrome acorn lug nuts.

However, come to find out, the back of the package has different instructions than the Subaru owners manual.

The Muteki Super Tuner Lug Nuts are spec'd to a max of 85ft-lb. Subaru specs 89ft-lb for the lug nuts. Will the 4 less ft-lb be an issue? Is 85ft-lb enough to keep the wheel where it needs to be?




Then there are the cleaning instructions. I use P&S non-acid wheel cleaner on my wheels. Hope the lug nut finish/paint can cope.




I guess it all comes back to the "if I had known, I probably would not have bought them" mantra. The package is open and I cannot return them. Live and learn, I guess.

Do other painted aftermarket lug nuts (closed end) come with similar disclaimers?

There is nothing there that says a max of 85lb ft.... Torque them to your car's spec and enjoy life

umm, step #3; or maybe I'm missing something. There are instructions in te internal instruction sheet that also say no more than 85lb/ft torque to these lug nuts.

The fact that is gives a range of 75 - 85 seems low in my experiences. I've never come across a lug nut torque spec in a manual that said "75lb-ft".

I'm curious if the spline design of these lug nuts can't handle more than 85lb/ft or if it has to do with the seat design...or the durability of the paint.

I guess in the end an additional 4 pounds is manageable (5% in the grand scheme of things).

When you get your car aligned next time the alignment shop is gonna put them back on to 100ft lbs with an impact.

Worrying about 4ft lbs is pointless

Anywhere from 70-100 is pretty much fine

I put mine on with a torque wrench but only because I'm particular

Step 3 is just a generic instruction... Post up the inside... But 4 lb ft is nothing... Like finger torque

ok, so I was mistaken on the inside card; my apologies There is only the back of the packaging.

as far as generic instruction thing; I am leaning toward this as the reason for the 75 - 85 number shown on the back. They (Muteki) use the same packaging material for ALL lug nuts for this style and they cannot possibly get the torque spec correct for each and every size and thread pitch.

So, to play it safe, they spec a range and get people close. 85 lb-ft is 95% of what Subaru specs for their lug nuts on their factory allow wheels, but might be more in line with other car or manufactures.

My Mazda owners manual specs 80 - 108 lb-ft for the OE 21mm nut on the factory allow wheel. So, with that info, these Muteki Super Tuner Lug nuts would fit into that range.

I will move on from this topic and torque these Mutekies somewhere btwn 85 and 89.

Oh, I do not let tire places rotate my tires. The only time they touch my wheels/tires is when it is time for new rubber.

Unless you have a calibrated snap on, that you calibrate on a set frequncy... You have never torqued to 89.

If you are using walmart special that you have never calibrated, ie 99% of this forum and 98% of shops, you could be off by 20%.

You got 5 lugs per wheel for a reason, the reasons i mentioned above are 4 of them.

4ft/lbs is nothing. Metal, lugs, or lug nuts don't magically snap if you go 4ft/lbs over. Pretty much any bolt is rated for X but can be tightened to Y. Look at all the oil drain pan bolts listed for ~32ft/lbs and people ratchet them down with air wrenches. Easily 100ft/lbs.

I've used various torque specs for my Subarus. I've probably used 78 ft/lbs for the longest on my 2004. Technically it's rated for 65ft/lbs, per the internet. Factory service manual says 73.8. People do 70, 80, 85, etc.

On my BRZ I think it's rated for something like 89ft/lbs, but I've always used about 80 because I never checked and just used the same rating as my WRX.

Point is, there's pretty much a range of about ~30ft/lbs that's generally safe. Torque to ~85 and be done with it. Do 90 if you really want. It's not going to change a thing.

... just don't be dumb and do 50 or 150.

I have these same lug nuts GoFrogs, you can use factory spec for wheel nut torque without issue. I torque mine to 90 ft lbs with a snap on split beam torque when back on the ground.

I'm certain it is off by a pound or two. It is my go to for anything bwtn 30 and 140 lb-ft
