I m planning to replace my stock springs and debating between ibach prokit and tanabe gf210. any advise? please help

 

Either choice pretty much drops the same, though both are progressive and less suited for aggressive driving then other linear spring choices. The Pro-kits have the edge as far as peak stiffness goes vs the Gf210's.

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


Tanabe GF210 Series 350Z progressive springs 1”/1.2”
Spring rates in LBS 336/375 (only peak rates are published, softer initial progressive rates unknown)

 

I have the Eibach Prokit (1'' drop). Great springs IMO. Combined with great shocks for better rebound, sweet.

 

Thank All
