I am looking to lower my car slightly maybe like 0.5 keeping 18's on my car will the Tein H-techs do the trick for a coupe? I was also looking at the 350z S tech that lowered it slightly more .7 i think but stiffer spring rate. I'm not the best when it comes to this stuff so if someone could tell me whats the best way to go for what i'm looking for. And will this create any problems using my stock shocks? I still have to drive the car in the winter and dont want to be changing springs seasonal (new england :/) which is why I need a small drop. Also if anyone could let me know if the cambers will stay in spec without any camber kits that would be awesome. Thanks!

Man....the hounds are going to beat on you saying "Use the Search!!!!"
(Try it)
But ok...I have the H Techs for the Z on mine and I really like them.
3/4" drop front...1/2" drop rear. Alignment perfect...within specs.
Good Luck.

Ive been at this for over an hour searching various phrases of tein s tech, h tech and all combinations of various springs And the 350 Z H techs lower it that much? According to Intense Mororsports ... TEIN H.Tech Springs 350Z 0.3-inch Drop Front And 0.2-inch Drop Rear

Yeah...but remember....the spring seats are different between the Z & G.
If you put Z springs on the G, you need to add approx. 0.5" to the drop they list for the Z.
For me the H Techs are perfect. Not too low where i scrape all the time and alignment is out.....but gets rid of the SUV gap over the front tires.

You drive a coupe right? Just want to make sure of everything. Also did you cut your bump stops when you installed? And your on the stock shocks still? Thanks for all the frendly help man, its really appreciated

03 coupe.
No need to cut the bump stops.
Slightly stiffer spring rates...car feels more planted but not rough.

Thanks man

If only a slight drop, I would look for 350z springs.

Man.....I stewed and fretted....and searched....and asked.....
for months trying to decide what I wanted! LOL
No problem and good luck.
