live in the UK where a G is uncommon so therefore getting after market parts is a pain ! wanting to get a reasonable drop all over on my 2011 g37s (RWD) , i know i can use 370z springs which is still difficult to get, but does anyone know if 350z springs fit ? thanks guys !

 

Someone correct me here, but I think the free length of the rear Z springs is too short to work on the G.

Swift springs seem to be a good choice and there's plenty of pics and reviews here if you search for them. If you want something lower, there are other options from Eibach, Tein, etc.

 

Actually you might be in better luck than us here in the US for the KONI/H&R combo. I've only been able to find them on European sites and it sounds like a great setup. It says for the coupe but the sedan will be the same.

I have available 370z eibach springs from a 2010 coupe .. think this is a good choice just hope the drop is enough .. guessing more due too weight !

 

If you're looking for a little bit of a drop that will not be too drastic or require any other aftermarket suspension components, I would recommend Swift Springs. Excellent ride quality, improved handling characteristics, and just the right amount of drop for my tastes without throwing my alignment out of wack.

 

100% though does the 370z springs fit the g37s rwd sedan ?

 

Simple question to someone with previous experience or knowledge .. not something to start a debate .. winde your neck in ..

p.s - repeating the word *really* makes you sound like you have downs
