Im looking into upgrading the suspension on my Z. Looking at the eibach sportlines but dont know what struts and etc to get along with the springs. What have most people had the best luck with? Any suggestions would be great. The car will be mostly a street car with a little bit of strip time on it (2-3 times a year)

 

if you plan to drag race it....lowering springs are about the WORST mod you can do for the car.

stiffer rear springs and a lower center of gravity will reduce weight transfere and negatively affect launch traction.

the sportlines are a big drop...maybe try the pro-kit.

but for a stiffer suspension on the street, the prokit with some Koni SA shocks work well. also look into other upgrades like sub frame connectors and lower control arms and panhard bar.
