I think there was or is a perceived notion that some wheels out there are not for daily driving due to the material used, i.e. Mg. Everyone SHOULD know that forged wheels are lighter and stronger then any cast wheel and very well suited to daily driving. With that said, Mg wheels are even lighter and just as or stronger then Al wheels. They also carry thermal properties that make them better for racing. Here is a short articel I found on Mag wheels becoming standard instead of Al. Of course they will be cast, but still a good alternative to Al because of cast life and overall wheel quality.

NewsUSA) - Automotive enthusiasts can now upgrade their vehicles with high-performance, forged magnesium wheels adapted from Formula One racing designs.

Magnesium.com recently announced the introduction of one-piece, forged magnesium wheels for street use in North America. The wheels are 20 percent to 30 percent lighter than forged aluminum and offer increased safety and performance.

"The U.S. wheel market is quite formidable and we intend to supply a smaller but very important segment of the 100 million vehicle wheels used in North America," said Mark Lisnyansky, president of Magnesium.com.

The magnesium alloy wheels are initially available in 20-inch and 22-inch sizes, and are treated with a high-tech anti-corrosion coating. The company will also be developing wheels in various sizes and compositions for specific North American applications.

"Steel wheels are becoming nearly obsolete and the prevailing trend is toward cast aluminum wheels," Lisnyansky said. "While most people are not familiar with forged wheels, performance car enthusiasts know that forged wheels offer significant advantages. And forged magnesium wheels, which are lighter and much stronger than their aluminum counterparts, are the next logical step in optimizing vehicle performance."

Magnesium wheels offer consumers improved safety by shortening braking distances and delivering higher acceleration rates as well as improving gas mileage. The "dampening" factor of magnesium allows for vibrations caused by road imperfections to be absorbed six times more effectively.

Using specialized aviation industry equipment, the company has been producing Superbike and Formula One competition wheel forgings for many years. The wheels are forged in Russia by a subsidiary and then machined and finished in Italy.

Magnesium.com is currently conducting a "Best New Wheel Design" competition and is negotiating with several large distributors to establish a joint machining and finishing facility in the U.S. The company is also considering an acquisition of or a joint venture with a local wheel company with an existing high-end market presence and brand-name recognition.

The technological innovation brought to the production system and the competences in the managerial field brought by Brembo S.p.A Group have enriched the know-how of the company and reinforced its leadership in the production of forged magnesium wheels.

The results obtained with the exclusive tecnique of simultaneous pressing and multidirectional forging allow a further weight reduction of the wheels, yet guaranteeing resistance and reliability superior to the forged wheels.

In the last 2 years, Marchesini forged magnesium wheels with the “Y” design have substituted the cast magnesium wheels used in the GP and Superbike world championships. Marchesini forged magnesium wheels guarantee a 30% to 45% weight reduction compared to the original ones, which correspond to a 25% inertia reduction. Forged wheels are perfectly balanced.



A set of forged magnesium wheels weighs 1.2 kg less in comparison with a set of cast wheels. The reliability is guaranteed by the exceptional mechanical characteristics of the special alloy of magnesium used.
