Yes Fuchs is still in business and Porsche is selling or at least showing the they have some sizes of 15" Fuchs and 16" Fuchs available. Last time I checked at Sunset Porsche in Oregon the 16x9's were around $830 each. And 8's were more expensive than that.
Normally Fuchs will bend before breaking but there have been more of them showing up with cracks and one on a thread here which broke (didn't bend). Porsche uses cast wheels on the cars now which are x-rayed to verify integrity. So cast wheels are not as bad as everyone seems to think they are as they have been designed with the manufacture process in mind and making them strong enough to deal with the forces that effect them. Even cars like the Ford GT came with cast wheels as standard equipment and offered the forged wheels as an option.
Wayne here at PP sells the Euromeisters and the Fox wheels both of which are cast. They are both heavier than the forged Fuchs to give added strength due to casting the wheels. No reports of ether failing on the street or track.
Remember most of the cars on the road have cast wheels not forged and we don't seem to worry that they will come apart and cause great bodily harm. My Porsche does not see pot holes like my daily drive sees and around here there are some giant wheel bending ones. When was the last time we have seen cast wheels that come on most cars come apart unless they were damaged.
