Well, I just picked up some Tein S techs for a G37 coupe... I was wanting a good drop and hope this will be sufficient for a little while until I get coil overs...

I have an 06 G35 with sport suspension...

Im hoping the 35 is heavier than the 37 and it'll give me a little more of a drop...

 

Tein advertises the as 2" drop in the front and 1.3" in the rear...

 

I'm not sure if the Gen 2 springs will even fit your Gen 1. Hopefully someone more knowledgeable will chime in.

 

I'd go into the Vendor Marketplace and make some calls to em.
I bet atleast one of them has come accross this.

 

i thought the g37 was a little heavier than the g35 so i wouldnt expect more of a drop than on the 37 if they even fit

 

The G37 springs worked, not to sure about the drop tho.. It's not as low as I wouldve liked... Gonna start saving for some coilovers now...
