im getting some greddy type s coilovers. the store only has ones for a 350Z. he told me that the only difference is that the G ones are 8.23 kgs rear 10.22 kgs frt. the Z ones are 8.24 rear & 10.20 frt. he said other than that there 100% the same. is this true? will i be fine with these Z ones? will i even notice a difference?

 

dude I dont think he knows what hes talking about.
The spring rates hes talking about are totally made up. If you look though the spring length the 350z is a little bit taller. but it shouldnt matter anyways because the type s should come with the rear perches that should let you drop it as low as you want.
But the shocks and mounts itself should be exactly the same.
