I've got the Nismo suspension but now I want it lower. Should I change springs or would I have to change the entire suspension

Thanks,

Kevin

 

Changing the springs might not be a good option since the springs currently in there are already optimized for those shocks. They were meant to work together. If you add say...Eibachs it might not feel right.

Eibachs + Konis should be a good choice for you if you don't want to spend much money.

Otherwise go with coilovers.
