Just need opinions on these two. I've try searching and only found the DF comparison...for the coupe that is.
Tanabe GF-210
Design: Linear F & R
F Drop: 25mm (1in)
R Drop: 30mm (1.2in)
F Stiffness: 6kg/mm (335lb)
R Stiffness: 6.7kg/mm (374lb)

350z Tein S-techs
Design: F: Progressive R: Linear
F Drop: 17mm (.7in)
R Drop: 14mm (.6in)
F Stiffness: 6.9kg/mm (386lb) (+23%)
R Stiffness: 7.2kg/mm (402lb) (+16%)

But most importantly, how's the...ride, bounce, stiffness, sag durability, etc.? Again...NOT the DF210s Thanks
