It also includes bigger swaybars, that's all I know.

Found the answer in an old post.He wasn't called a guru for nothing

Per Viken, "All the US specification 993s came with 2 different suspension options. The standard M032 setup and the optional M030 sport chassis. You will have to look at your car's option sticker to see if it came with the sports chassis M030. The M030 option was only offered on the Coupe models including the Carrera S and Carrera 4S. The 993 Turbo already had the M030 sport chassis with the exception of a slightly firmer rear spring to compensate for the heavier rear weight. The M030 sport chassis option included firmer shocks and springs and slightly thicker anti-roll bars. There were some slight anti-roll bar differences between narrow and wide body cars as well. The ride height of all US 993 cars were the same regardless of suspension setup. The US cars were approximately 20 mm higher in front and 10 mm higher at rear than the standard ROW (rest of world) cars. On the other hand, all US cars were approximately 30 mm higher all around than the ROW M030 equipped cars. A US car equipped with the factory M030 chassis could be retrofitted with the ROW M030 springs for a 30 mm lower ride height without having to change the shocks."

The front drop links (which attach to the sway-bar) are also upgraded. They are much thicker and made of cast steel.

Out of curiosity, I searched (!!) this forum to find out why my manual says that the M030 ground clearance is 10mm higher than the alternative. My manual contradicts the above thread. Any idea why the sport chassis ground clearance would be higher? It doesn't make intuitive sense.
