You could look for part numbers online and compare between the 2.

wait a min! the 370Z springs should fit our G, they may have a different part number but that's about it.

They may very well fit, but the springs are designed for different applications. I bet the OP could use the Z springs on the G, but Swift developed certain springs for certain cars based on the unique characteristics of that particular car. If you're going to use a spring that is not made for your car then you may as well just cut the stock springs... (Please don't do that.) My $.02.

G37 Coupe - Sport Springs (4N906)
Spring Rate
Front: 10.3Kg/mm; 575 Lbs/Inch
Rear: 9.7Kg/mm; 542 Lbs/Inch

Drop
Front: -33mm; -1.3Inch
Rear: -25mm; -1.0Inch


370Z - Sport Springs Spec-R (4N905R)
Spring Rate
Front: 10.0Kg/mm; 559Lbs/Inch
Rear: 10.5Kg/mm; 587Lbs/Inch

Drop
Front: -30mm; -1.2Inch
Rear: -25mm; -1.0Inch

Thanks! good info. I figured they were similar in size but I wondered about the spring rates, especially since the G is heavier than the Z. Thanks again.

The answer to the question is yes, yes you can put the springs from a 370Z on a G37. Are they the same? No. Now should you? I would not recomend it.
