A standard (non-cup) 182 with the cup suspension, seats and spoiler upgrades is still a full-fat. It is called that unofficially because it has the extra weight and the things that a cup doesn't have like recaro seats and xenon headlights.
The cup suspension has lower ride height, stiffer springs (20% front, 15% rear), re-rated dampers (+20% front, +10% rear), strengthened front wheel hub carriers and revised steering geometry.
