OP, i've run a couple of setup. The first one are Swifts, they performs great and the meet the hypes all our members here said, simply put it's an amazing spring. However, due to fact thay it's too stiff for our roads here so i sold it off to one of my friend. My current setup is H&R and mind you this is by far the LOWEST spring for 370Z! They def feels a lil softer and much more comfortable and less bouncy for our roads here in Brunei. However, i can still attack the corners at will with comfort
Take a look at my thread if you'd like to take a peak of what my setups are
