Porsche AG attempted to reuse (economy of scale) the 996 suspension to the maximum extent possible but reluctantly had to reengineer it entirely because of the added stress and weight. It's been rock solid for me so far (nearly 60,000 miles on my MY06 car). After tire replacements I always have the alignment checked and find it still spot on--within spec.
