EK9 suspension is a great upgrade compared to EJ/EK4 suspension. Check the spring rates on goolge or other forums to see the difference. Think the EK9 springs are almost twice as stiff as EJ9 springs.
Ride height is about 10mm lower than EK4, and the EK9 in the pic above is definately lowered.
Im running on 16s (45 profile tyre) with EK9 suspension, and there is about a 60mm gap between the top of the tyre and wheel arch.
