The Ohio Random Thread... aka We Should Probably Be Working

edit- John, that guys wheel came off because he painted his stock calipers red. Not because of the lug nuts.

never had problems with my orange calipers, just the rest of the car
 
This blows...

I knew about the Voltron issue but now others.... snow balling as always when it comes to a CS product fail. It seems they have constant issues with QC.

If race teams use steel lugs, why would a regular joe use aluminum?

CS is to blame for making a the product, but the buyer is at fault for buying them. Plus, on all stock plus Konig Illuisons...what was he really going to gain with aluminum lugs?

That being said I did run aluminum lugs for about 2 months, every week I had to retighten them and then Phen made the same statement above and I switched back and never had a problem. Thanks for the common sense Phen!
 
As for the lugs, he was using spacers with an aluminum lug and stock length studs then went autox, what else could he have done to ask for more problems.


And menchies I will be at tomorrow, with the kiddo, but no Mazda. Also, wife has the night out, so its just me an the little guy. First Menchies meet FTW!
 
There have been other guys without spacers that have had failures as well as voltron with his bolt on spacers with secondary studs. He actually had the issue the same weekend he ran an 11 second quarter mile.
 
949racing uses their brand aluminum lug nuts on their race cars. When the cars come in for a tire change they pick cold ones out of a container and put them on.

I ran the same lug nuts for a few years, with and without spacers (25mm). Now granted, I wasn't on a race track... But I do drive aggressively and on the street there's a lot more potholes/bumps/etc....

With all that being said, the single most awesome upgrade I did to my 2 was the CS rear torsion bar. Which promptly broke 100% around one of the two welds within 2 days of installing it, and it even happened "off road" at Nelson.

They sent me a new "custom" one, which I think was just solid aluminum instead of hollow. And painted instead of powder coated. Whatever. Best mod to the car by far.
 
I use 949 aluminum lugs on my Miata which sees a fair amount of track time. Never once have I had a problem.

Oh, and they are considerably lighter than steel lugs.
 
I want to rig up a set of microphones so you can sync some good audio along with your GoPro. Though I'm sure someone already makes a kit.

I'll have to watch the whole thing at home later. That's a cool angle though, #2. I hate it when it's on the bumper and you don't really get a feel of how the car is rotating. It's like that first person view in Forza I hate so much (that Phen uses). haha

Hey now, I use the in-car view so I can see the dashboard and stuff! Makes me feel like I'm not actually just sitting on the couch, getting fat.

Speaking of... let's get some Forza going again.

I've had some no-name brand aluminum lug nuts (recommended by AutoRND) on the RX-7 since the first set of RPF-1's. Granted, the car only saw one Hyperdrive and 7/8's of a single HPDE weekend but I've had the wheels on and off more times than I can count. Not once were they loose. Does CS recommend a certain torque? Maybe that wasn't followed or isn't correct. I know when I got my first set of RPF-1's the manual that came with them had recommended torque values for both aluminum and steel lug nuts. I think I was torquing them to 85 ft-lb but I can't remember. I need to check the manual again. Yes, my wheels came with an instruction manual...

Speaking of... let's get some Forza going again.
This got me thinking. Would anyone be interested in a "league" where we all race comparable versions of our own cars? It's been a while since I've placed Forza but I'm pretty sure they have most Mazdas. I just think it's be kind of fun to try to gage what our cars would do versus one another. Sure obviously concessions would have to be made (no USDM MSP and N/A RX-7's in Forza) but I imagine we could get pretty close.

I got random aluminum lug nuts from Amazon and use them on the MSM, most of you how I drive :)

It would probably be a good idea to get longer studs though
 
I think there are two problems this dude encountered.
1) the CS are a two piece aluminum (not a problem in itself)
2) he ran wheel spacers, and essentially was only holding on by 2.5-3 threads. Now, had he installed longer studs to use 75-100% of the available threads in his new extended lugs, he would have been fine, imo.
 
embrace the stretch! And yes the rear is all that is stretched. Fronts were fine

Everything points to the guy not using extended studs.


I dunno about torque specs. But I torque mine to 80.

I typically do about 80-85 as well.

In that thread, the guy says Corksport recommends 65 ft/lbs...that seems too low to me though. My McGard spline-drive lug nuts have the same 2-piece design, but I made sure I didn't get Aluminum lug nuts. I've done 2 autocrosses and a track day at Mid-Ohio on them without any issues.

Yep, user error. And unfortunately MSF is going to blacklist CS for it.

The guy at least said he wasn't trying to start a flaming war against CS. He said he was just trying to warn people not to use their lugs with wheel spacers. Regardless, I can almost guarantee he would have had the same exact issue with wheel spacers no matter what lug nuts he was using. You have to make sure the lug nuts utilize enough of the threads.
 
Theres posts in that thread of failure without spacers as well. One while torquing them to the recommended 65 ft lbs
