So I guess the Tanabe Sustec Coils dont come with the pro210 springs as advertised for the g37, but I am almost positive the front ones are the pro210,

So my issue is the rears, any solution on how to go stiffer, In my other thread people mentioned going linear springs, but since the g37 rear setup is shock spring seperated, do you have any suggestions on where to get springs, anything from the g35/350z guys that would work?

and if indeed the front sustec pros on our cars is using pro210 whats the part #? since in the manual it seems like they refer to the front springs as a different kind.

 

Call Tanabe USA and ask them for the spring diameter and length for the Sustec S-0C for our application (TSC130). Then you can pick any spring you like that is the right size in the stiffness that you want.

 

Tanabe is sold out on the kit, and have no idea about the sizes, maybe I am just talking to the wrong person, i have to find my manual.

 

Ask for James. Or you could always measure them yourself.

 

Best way if calling tanabe... They're really helpful when it comes to this stuff. Pretty sure you can change the rears just need the diameter.
