I have an 06 G35 coupe automatic. About to by some shocks, but I want to make sure I get the right ones....I see options for this Sport Suspension. How do I know if mine has the "optional Sport suspension"? Shouldn't there be a button on the inside for that or something? I don't have a button for sport suspension or anything that I know of...

 

Check your shocks. I believe the Sport suspension is red.

 

yes shocks painted red is sport/rate version, black is standard spring rate/color.

 

So I can't just upgrade to sport suspension by getting those....I need to get the standard fit? I am almost positive mine are black.

 

I believe that for 2006 even the sport shocks/struts were black. I know that is the case on my 06 Sedan. If your car came with the 19" wheels, it should have the sport shocks/struts.
