you gotta remember that the cup suspension, along with the trophy, is among the best hot hatch suspesnion setup to hit the road ever. In order to improve on it you gotta spend serious wedge, simply slapping some lowering springs on it will make it look cool, but it wont sort ur handing out overall.
these things are b-road weapons, dropping it 30-40mm on springs alone will make b-roads a no-go zone, lol. (if you like your spine)
