Check your FUCHS.... This is a Public Service Announcement
Gang,
Another thread just inpired me to write this... Check your Fuchs for cracks. A recent PCA racing newsletter, my cracked wheels, and some others I've seen recently make me concerned. Fuchs are getting old, and likely brittle. I've seen more than a dozen cracked fuchs wheels in the last 12 months... FIretunately none that were found "the hard way". Please check your wheels carefully next time you have them off, preferably soon. THe spokes, and where they join the hubs are most common areas. CHECKYERFUCHS!

They're not getting brittle, they're just reaching the end of their fatigue life. The harder they're used (loaded from weight, horsepower or racing) the shorter the life. Unlike steels which can be designed to an infinite fatigue life if the stress is lowered to the so called endurance limit, all aluminum alloys have a finite fatigue life no matter how low the design stress. You can't cheat this degradation in a Fuchs Porsche wheel or a WWII anti-submarine patrol plane masquerading as a slurry bomber. Some day all the forged aluminum Fuch wheels (and the 911's too) will be used up but we'll either be onto something else or we will have returned to the dust ourselves. Check for cracks and drive it like you stole it! Jim
