Hey, I just sold my 2007 G sport sedan, and bought 2010 g37 sport coupe. I had bought Tein htech ( gold ones ) -1.5/-1.3 inch. but before i mounted on my G sedan, suddenly I sold the car so IS IT POSSIBLE that somehow those springs would fit on g37 coupe ? What is the main difference between them, maybe its possible to mount them ? have you ever done something like this or heard ?? Thank you...
