Hello,
you can always check the OEM suggested ride height, the workshop manual should mention that,
if your car is in that range,
you don't need to change anything.
IF you do decide to raise the height, either by inserting rubber bushing, or changing the suspension,
please ensure that you maintain the ratio of front and rear height, and also understand that
doing such an operation will set you back in terms of safety and stability.
regards.
