Best springs for track day?
 

Hello!

Any one tracking the Z with lowering springs? Which one is best bang for the buck? :dunno:
Is Tein to soft?

Swift is popular and one of the two two eibachs , just don't remember what one.

sportlines are 1.2 inch drop, pro-kit are 1 inch drop.... dont know spring rates off the top of my head

i have 2 buddies that track with sportlines, myself and another friend have the pro-kits

You're best bet is the Swift Spec-R, they are one of the few springs that actually increase spring rate and lower the car...its going to be more for looks at this point though as to get an actual advantage you'll need MUCH higher spring rates.

Stock revised spring rates

F: 314
R: 427

You'd probably notice a bigger gain using a bigger front sway bar than lowering springs

IMHO, when lowered on drop springs with large drops (more than 1"), there isn't enough bump travel on hard corners with the spring rates drop springs provide.

I run the 2008 Nismo springs, does not lower the car (which I prefer) and has stiffer spring rates that work very well at the track. You can look for a used set or order them new from a Nissan dealer.
