This sticky from GSedan35 has the following info for the coupes:

Oem springs G35 coupes with oem 17’s & 18’s
Front:314 Rear:342

Oem springs G35 coupes 2005 only with oem 19’s only
Front:314 Rear:427

The single numbers imply linear, rather than progressive springs.

 

lol..you would rarely see OEM springs being progessive springs.
As a matter of fact, we only have OEM linear springs

cheers
