Looking for new springs

[Tim30250]

I'm about to begin my search for some new springs. I've decided that my car needs to be lowered a bit. Here's what I need to know...

1) Who even makes springs for a G37 sedan?

2) Which spring, in your opinion, would be the best choice for a modest drop (maybe 1" or so) while NOT yielding a rough ride?

Tein H Tech normally provide the mildest drop on any application. I will check tomorrow to see if they are available. The ones for a g37 coupe will work as well.

Do you have the sport package?

[Tim30250]

No sir, no sport package.

Your chassis is no different than the 07-08 G35, which they do make springs for. The H techs provide a 1.5" drop front and 1.3" drop rear. Now being a non sport suspension a shock/strut upgrade would be recommended if you decide to lower your car on any springs.

The eibach prokit gives a 1.5" drop front and 1.3" drop rear.

Thank you, that's great info! I've had the Eibach Pro-kit springs on my BMW for years and I love them. They provided the mild drop that I prefer with increased handling, but without compromising ride quality. H Tech seems like a popular choice for the G. How do they compare to Eibach in terms of ride quality and handling?

Working on compiling some info on spring rate comparison.

Working on compiling some info on spring rate comparison.

That would be much appreciated. The only company I was able to find published info on spring rates for was Tein.
