I have a non-sport g35 sedan...

i've read that putting the Z springs will improve handling + lower (by how much actually?)

but will the OEM Sways do anything special?

Check the sticky at the top of this section for info on the springs. There is a difference between Z springs, depending on year. Some people with G sedans use coupe springs in the rear and Z springs up front.

As for the sway bars, they are all aparently the same.
