Sportline or Pro-Kit?

 

both, go sport in the front and proline in the rear. ftmfw.

 

is that practical? like more than just gettin the same front and rears

 

In case specs matter in the buying process

Eibach 350Z progressive springs 1”/1”
Spring rates in LBS initial/final front 296/384 initial/final rear 316/421

Eibach 350Z sportline progressive springs 1.2"/1.2"
F: 239/400 R: 257/435

Peak stiffness isn't that different between the two, but the sportline setup has a really high rate spread between min and max. I won't touch progressive springs, but between the two I'd pick the Pro-kit.

 

great info thanks
