i put an eibach pro lowering kit on my 2011 g37x coupe and i was wondering if those same springs are compatible with my 2015 q50 premium awd?

 

Going by Tanabe's website I'd say they probably aren't compatible.

Tanabe used the same spring part # for all second generation G35/G37s (coupe, sedan, AWD, RWD) but lists a different part # for the Q50s.

Eibach is much more vehicle specific w/ their springs, so If Tanabe isn't using the same springs on the Q50 I'm almost 100% sure they aren't "swap-able"

It's possible they will physically fit, but not worth it IMO.

 

eibach used the same front spring on coupes and sedans. idk about rwd vs awd. just the rear springs were specfic to the coupe or sedans
