Sorry guy if it's a repost but just really wondering are they sharing the same chassis stuff? does all the aftermarket coilovers or springs can swap between 350Z and G35? From greddy's website, I get two different part number for coilovers!!! Please specify thanks!!!!!!!!!!!!

 

Core suspension parts are indentical between all RWD FM platform varients. Shocks and springs differ as do ride heights. Most coilover manufactuers produce the same products for both the G and Z. A select few do make coilovers specific for the Z and G, though this is somewhat rare.

In neighborhood of the Greddy price point I would recommend Cusco Zero2's instead, that or HKS RS.
