if u wan remain comfortable, try install air suspension controller...~ im not sure how muc issit, but kinda xpensive~ Like kev-tec said, potong spring paling cheap... actually it is bad idea, sumtimes if potong salah, ur car got many weird sound when conering or on bumpy road... so if potong it is kinda risk~ for lower spring, i think APM better, around rm100 i think.. not sure bout it, but lower spring still sacrifice comfort, but it is really stable when u goin to high speed. sum air suspension is automatic, once u go more den 80kmh (u can set how muc spd u wan) it will lower automaticly
