LOL. I wasn't disagreeing with you. I was disagreeing with the entire misleading title of this thread. This is ridiculous and should be either edited or locked and buried. Jordan and 360Forged have had their problems in the past, but that doesn't mean they deserve to be collected by someone else's unrelated incident.

Hello to All,
Just wanted clarify a few things so the forum community is better informed on forged wheels:
Forged vs. Cast Alloy:
Forged & Cast are the 2 primary methods to manufacture wheels. Forged in simple terms is the product when billet aluminum is pressed/forged into a specific form to make aluminum much more dense and stronger than it's initial state. The forged aluminum must then be machined into the geometry for the wheel. Cast is when molten aluminum is poured into a cavity molded to the geometry of the wheel. There are several different techniques to accomplishing either in which some methods have proven to be better than others. For 3 piece center sections Rotary Forged is the method of choice for most U.S. based manufactures. There are other methods but uncommon throughout leading brands. As within forged wheels, there are also different methods to cast a wheel. Low pressure casting would be the method for most OE wheels. Spun forged is a technique most commonly known for the manufacturing of the rim half components of a wheel. In both methods heat treatment is done to strengthen the integrity of the aluminum. Forged aluminum however is always going to be stronger the cast aluminum in it's remanufactured state.
Components:
No matter what any wheel manufacture claims, all U.S. manufactured wheels are generally equal in quality in they're crude form prior manufacturing. There are only 3 forging facilities within the U.S. who cater to after market wheel manufactures. There are only 2 primary sources rim halves. Essentially crude material being used for manufacturing is sourced from the same providers throughout all U.S. based manufactures. There are sources over seas but to stay on topic I'll discuss U.S. manufactured wheels which is what's being questioned.
Quality:
What a manufacture does with the components is what differentiates them within the industry. The quality of a wheel comes down to wheel design, application, machining and finishing.
- Wheel design: Some manufactures cater to a particular client base in which some designs are better suited than others. Wheels design is the primary factor for most consumers.
- Application: The manufacture must be knowledgeable in fitting wheels correctly. There is no standard when it comes to custom manufactured wheels and there's definitely no guideline to refer to. Each manufacture develops their own offsets, clearances and overall dimensions of a wheel. Some just do it better than others..
- Machining: The way a wheel is machined becomes a factor for the overall appearance of a wheel. Although all wheels require prepping prior to finishing, A wheel that is not properly machined will shows signs of shattering or uneven machining.
- Finishing: Low volume forged wheels are hand prepped and finished on a per order basis. This comes comes down to the craft of the painter doing the work. Automated finishing is generally only used for cast wheels manufactured in large quantities. Powder coating when done at the correct temperatures and duration does not affect the structural integrity of the aluminum.
Wheel failure:
Performance wheels for obvious reasons are more prone to scrutiny when a failure occurs. The fact is that no matter the brand, all wheels have a breaking point. That breaking point is generally determined by quality of components and geometry of a particular design. In the case of a U.S. manufactured wheels this mainly comes down to wheel geometry. Varying wheel geometries absorb stress loads differently from design to design. Various criteria is addressed by a manufacture throughout the development stages of a wheel. As we all know there's the always so very important "How light is the wheel". What needs to be understood is that in order to lighten a forged aluminum wheel, additional aluminum would need to be extruded from the crude forging. In other words, the lighter a wheel, the lesser of a load that wheel is likely to withstand. Wheel manufactures as with us, strive on providing wheels for optimal performance. There is however a balance between weight and strength that is considered for all developments. We as a manufacture can create the lightest forged aluminum wheel on the planet if we set out to. Can it be installed an a 1200 horsepower track car? Sure it can… Is it going to crack? Yes… Will we sell it to you if we knew where it was being applied? Definitely not… It is imperative a to discusses the intended use of wheels when making a purchase. A knowledgeable manufacture should always help make an informed decision appropriate for the applied use.
Refinishing:
Refinishing and improper reassembly of a wheel can also cause it to fail. Some stripping agents corrode aluminum. In some cases heat is used to remove finishes for refinishing which also fatigues aluminum. Disassembling and reassembling a wheel also requires certain procedures. It's highly recommended you contact the wheel manufacture to service wheels.
Tires:
Tires can also add considerable amount of stress to the wheels. Drag radial and competition tires use different compounds of rubber which enhance traction and increase stress on the wheels. Tires selection should also be discussed at the time of a wheel purchase.
This is not an attempt to discredit any wheel companies. We are manufactures and this is what we do so please do not attempt to contest this post. I just want to share some insight on behalf of Forged Distributing. Safety is a priority to us. We can always be reached for any questions or concerns regarding any of our products. .
Thanks,
