hmmm, kind do able.
stock 2001 astra equipe sideskirt height = 7.5". meaning lowest point of car (floorpan under drivers feet = 6.5")
that would mean the lowest point of this car would be 6cm.
looks like there is more gap between the tyres and archs on the front wheels so i don't think its been dropped as low as they say. maybe 4.5cm is more realistic.
