Infiniti Q50D (2.2 OM651 diesel). 1820KG curb weight. Currently rocking BC Racing BR coilovers. 9K front 4.5K rear. Rides nice but has some flaws. Over larger dips in the road the car really compresses. Even worse when there are passengers in the car. It is pretty comfortable tho. I want to go 1-1.5cm lower in the future when I add aircups (for obstacles) and am afraid of crashing the frame on the ground with my current spring rates at a lower ride height.
What could I do spring wise to get more stiffness over those bigger dips and less compression with passengers whilst not being crashy during normal driving? I was thinking 10-11k fronts with 6-7k rears but not sure on what to do. Dampers are set 16/32 front and 10/32 rear.
