I am trying to figure out what set of springs would be best for what i want and the area i live in, I have heard the springs will drop different from what their site says.

PLEASE tell me from your experience how much yours dropped

 

everything you need to know is in this sticky:

I have decieded to go with 350z H-techs in the next couple weeks... I was waiting for the weather to break first... Its getting close. I cant wait...

 

I'd love to see what these look like when you get them installed. I am pretty unsure what to do, if and when I ever find some OEM 19's.

 

^^ there are tons of threads and pics on these springs.

here is the thread i started when i first got mine almost 2 years ago to start you out... but you can search for plenty more
