Classified for the race? do you mean classified IN the race?
Yes they are classed as disqualified. The classification is done subject to successfully passing post race checks such as weight limit etc.
They had excessive curvature on the rear wing. This could give an additional boost from the DRS along with improved rear downforce. It's likely that the infringement was very very minor. The teams tend to use the technical limits as a specification to aim for, so it's easy to end up 1/10th of a mil over.
Sauber will be pissed off, but it's only their fault. They showed good speed and are clearly very easy on their tires so i think they can expect more points finishes this season, so it's not all bad.

As far as I know from my knowledge, the problem with the rear wing gave no performance advantage as it was not part of the working area of the wing as it was on the upper surface of the wing.

As for it being wing curvature, there is no specific information yet as far as I know detailing that as the issue, it's the most likely but the info isn't concrete.

However, the rule they have most likely broken is the fact that the uppermost portion (the part that opens due to the DRS), the chord of the segment must be smaller than the chord of the lower segment in the same lateral place.

If this is the case I can't see any performance advantage at all, as if the curvature isn't less than the lowermost portion then it's going to let less air pass through thus hindering performance, however we shall see.

It is odd that it got cleared in parc fermé the day before but was found to be in breach today and that's the reason why Sauber are appealing, as far as we know they'll most likely appeal about how it is measured, as if it's done simply i.e. with a ruler there is a possible margin of error that could cause them to not be DQd after all.

HTH! !

A statement from Australian Grand Prix stewards said Sauber's C30 had breached articles 3.10.1 and 3.10.2 of the technical regulations. Those articles govern the placement and shape of the wing, but it is believed that the Sauber breached the curvature requirements of rear wing elements.

The regulations state that “no part of [the rear wing elements] in contact with the external air stream may have a local concave radius of curvature smaller than 100mm”, but the second element in Sauber's rear wing had too sharp a curvature and therefore infringed this rule.
