trying to find right suspension
hey guys i dont know much about the Z, just switch from a 05 wrx so i wanted to ask some people about lowering the 2007 Z. what would you guys think i should get if i want to get a nice clean drop on the car? and still get a similar stock ride?
If a like stock ride quality is the only real driving force behind your desire to lower the car 1", pretty much any 1" drop spring will do. Though you do want some spring rate increase over oem in the front to help keep you off the rather unforgiving front bump stops that you can't cut.

I have the Hotchkis and it's very nice. Seems to be same as stock with a little better handing. With the sways there one great package together.
But I like what Gsedan35 said. I've been planning on going to the Eibach for slightly better spring all the way around.
