Ark GT-S
I recently switched from Swift to Ark GT-S springs. I loved the Swift springs, they just didn't lower the car enough for me. The Ark GT-S springs, on the other hand, just gives the Z a more menacing stance. With that said, my car's too low that I managed to destroy the front aero diffuser, left and right air guides, as well as bend both of my FI canisters in 48 hours. My car can literally scrape on a burrito. I'm switching to coilovers.
