both drop the same 1.2/1.2 on the Z. i'm looking for a slightly dramatic drop. both at progressive. i'm pairing these with tokico d-specs (350z). can someone tell me which is better? i want a feeling of slightly stiffer then OEM sprots tuned. does it really matter since i'm getting the d-specs? and i can just adjust those to the stiffness? is there any problems with pairing progressive springs with the d-specs?

 

ok, anyone have experiances with either of the springs?
