997 suspension long term durability on urban roads
#17
Porsche tightened up the 997 suspension significantly over that of the 996 when they made the 19 inch wheel a standard size for the 997. (They found that the 996 suspensions were literally beating themselves to failure). 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.
