What more can you want he said stop by and he will give you the information you ask. I think there are a lot of other companies out there with a whole lot less in terms of testing like the one in the very first post of this thread. And the other 300 "forged" companies out there. |

When you say required, I assume this is regarding ADV.1's own parameters? Do you have any pictures of your test subjects? Are wheels that STL labs has tested that you can post pictures of? Quote:

This still does not explain why you are testing that wheel at a load rating of 545kg when the wheel is a 18x12" porsche application that should have a load rating of at least 650kg for the rear. Quote:

Take the time, read the posts, address the questions asked or we can only assume you do not have an answer to our questions. BUYER'S BEWARE: It is your responsibility to be informed and make an educated decision on your wheels purchase. There are a lot of wheel companies out there. Make sure you purchase your wheels from a company where wheels are engineered, designed, tested and certified and are transparent about it. Where a quality/testing certificate can be issued upon request. Pricing does not determine quality. The most expensive could be the worst, and more affordable ones could actually be better. After 30 years in the steel industry I cannot see any manufacturing/designing firm operating without an engineer. I`m out of this thread guys. Everything will come to the light soon enough. |

You cannot be more wrong. Please don't make any comments regarding wheels testing, engineering and certification since you are misinforming a lot of people and do not have any clue of what you are talking about. |

I`m an old and retired engineer with too much time in my hands. I graduated too many decades ago from Georgia Tech and hold a B.S. in Mechanical Engineering, a M.S. in IE, and Six Sigma black belt certification, Was a past member of SEMA council, know too many people in the automotive and steel industry.

No I am not an engineer. I am not that full of myself that I feel that I have to have a degree to figure something out that my 4 yr old could do. If my 4 yr old designs a wheel and it passes the same physical test as one you the engineer designed is it not good enough. Now it may not be as lite on the first try as yours but my 4 yr old is still learning. I used to work for an engineer and live in Champaign IL around many Future engineers. I have never met one that had one bit of common sense. Not one that could change a flat on their car. They always try to look at the way to techinical side of things so they look smart. |

I was told I was completely wrong which I doubt because I am holding the SAE test in my hand and looking at it. Maybe its wrong who knows. Typical engineer he knows everything and nobody else can figure it out. In his eyes I probably cannot read the SAE test because I do not have a degree.

I don't give a crap if I have credibility or not. You guys resort to name calling what's next you gonna tell me your dad could beat up my dad.
If it passes the SAE test who gives a rats ass who did the drawing. I would take a wheel that passes a physical test designed by whoever over a Mechanical Engineer designed wheel that only had FEA. But hey that's just me. |

Interesting thread.
Anyway, I would like to add that just because a wheel isn't forged, rather, it's a gravity cast wheel, doesn't necissarily mean it's not worth having depending on brand, budget or type of vehicle it's going on. I am not advocating any particular brand and I am certainly not advocating getting any wheel that is a 'copy' or ripoff of another (certified) brand. I did have a set of gravity cast Axis Superhiro's on my 370z and I have to say, for an inexpensive wheel, they performed admirably. I had probably 20K miles on them with 3 track days (speeds up to 140 mph) and plenty of spirited street driving including some tail out fun, burnouts etc. I always detailed my own car and checked the wheels for cracks etc while cleaning. I've even pulled the wheels off the car for detailing and they were in great condition. Just a testament to those particular wheels. Like I said, I am not endorsing any brand (including Axis) but I have to give some credit where credit is due. As far as future aftermarket wheels are concerned, I would most likely go for Volks (ran Volk GTU's on my Evo) and NOT for a gravity cast wheel simply because weight (and strength) are concerns for me. Just wanted to share. |

Come on guys lets get back on track and end the name calling and insults. If we don't the mods will be passing out warnings/suspensions and maybe close the thread. Everyone has something correct to say.
Yes some engineers have their heads in the clouds or in the "ivory tower" and can barely tie their shoes. That being said even those guys probably make important contributions to areas other engineers would not be capable of working on. On the opposite end of the spectrum many engineers are both book smart and "street"/practical smarts. Its a bell curve of capabilities and dispositions like any other person/profession. Sure a wheel is not a rocket, not even close, but pressure loading, braking loads, acceleration loads, curb impact, sliding loads with their resultant stress and strain are not trivial either. Add in the possibility of fatigue in aluminum, casting vs. forging, grain patterns, heat treating, etc. and you absolutely have more than 99.9% of folks without an engineering background can appropriately digest and apply. If you are fine having a designer design one wheel in a series, test one extreme and call it good to go that is your choice. However, if you believe a critical load bearing and safety related item on a car (perhaps even more so a high performance car that very likely will see speeds well into the triple digits) should have an engineer, FEA, testing AND type certification as well that is also fine. Make your choice through capitalism with your own dollars. Either way let's get back on topic.

I agree there is a lot of good info in this thread. I agree with a lot of stuff you are saying swamp. All I am saying is that wheel technology does not change like other things in the world. The cornering, braking, accelerating loads on a xxxx pound vehicle are the same now as they were 30 years ago assuming the vehicle weighs the same and the weight is in the same place. Once a person could design a wheel for those loads they could probably figure out how to design other wheels for those loads without being an engineer. Last edited by db71; 04-03-2012 at 10:52 AM.. |
