all nismos have had the same strut tower bar and yamaha tuned dampers front and rear.
I bet you there is ZERO difference in the 2015 nismo versus any of the other years suspension wise.
do you see the circled areas? those two pieces are welded onto the nismo only strut bar. (whoop-ty do)
and this is the yahama tuned damper. there is one on the front and rear.
