Swift shows :
Sport Mach Springs for the 2015+ GT-R (Swift Part # 4N912).
Spec-R Spring Set 2011-2014 GT-R (Swift Part # 4N017R)
Sport Mach Spring Set 2009-2010 (Swift Part # 4N017), but they also list Spec-R as universal for 2009-2015
Looking at the spring rates :
Spec R Front : 1117 lb front and 615 lb rear
Swift sport Front: 840 lb and 392 lb rear
OEM Front : 799 lb and 382 rear
I’m having issues with G-Senor and AWD overheats faults since adding the springs and wondering if the spec R could be the issue by not allowing enough squat. Could also be why I was spinning so bad as well.
Anyone with a 09/10 use the Spec R ?
