Thanks everyone for the welcome. Would have preferred the car 5mm higher for our roads. Having said that, I have had no issues on our highways, even with 4 passengers on board. Rough roads however can be a little bumpy at lower speeds. Initially I had fitted a B&G spring set sourced from within NZ and the front kept bottoming out on small ridges like when entering a bridge etc. Turned out the springs were for a 530i hence too soft in the front. Present set is sourced from the US and does not bottom out even at higher speeds. Huge difference in the handling and cornering especially with the Bridgestone Potenza 285's on the rear. OEM setup was with 225's all round and the car had comparatively very very poor handling. Long trips are now great! Love the way the car drives.
