How to Clean Magnesium Wheels | It Still Runs

Magnesium (mag) wheels are more expensive than steel wheels because of their light weight, precise steering capability, better acceleration and greater breaking power. A mag wheel is also interchangeable with an alloy wheel because alloy is made from a coination of aluminum and magnesium. Mag wheels are popular for
