Swift Springs Question

I noticed there are two types of Swift springs.

The regular Swift Sport Springs and Swift Sport Springs Spec-R.

Will both of these springs fit the g37 rwd?

On the Spec-R springs it only list for 370z etc.

I've read that the 370z has same suspension setup as the G....

I would go for the springs specifically made for your vehicle. The Z has a significant difference in weight.

Need to know whether you have a sedan or coupe. Here's a pic for part numbers.

No SPEC R for the G37.

The 370Z is 75lbs per corner lighter.

You really dont want SPEC R on your G.

I have the Swifts, and coupled with Konis they are stiff enough, but still allow some comfort.

Agreed. I also have the swifts, and the 4N906 is what you want for the coupe, or the 4N908 for the sedan. (I've got the sedan springs and love them!)

I'm starting to learn that there are 3 types of people when it comes to suspension:

1. A person who puts the wrong suspension of their car in hopes of better comfort/ride quality. Ex. Different brand springs front and rear.

2. A person who puts the wrong suspension on their car in hopes of better looks/performance. Ex. This thread or Any kit designed for car X and put on car Y.

3. A person who puts suspension on that was designed and engineered accordingly. Ex. Any kit designed for car X and put on car X.

I personally feel comfortable in category 3, but I know there are other who will disagree. I think we would all hope that there was some engineering and thought put into the spring rates and ride heights and this is all thrown out the window when you make an a la carte suspension or start putting on any spring that will fit on the strut or in the bucket. There isn't anything wrong with experimenting if you have the time and money just know that no matter what combo you make you will never have a perfect drop, ride quality, and performance in a single setup.

I'm in category 2, I put coupe eibachs on my sedan (both RWD). Front is lower than sedan eibachs, rear is not saggy like sedan eibachs...i would say its perfect for me. My raked appearance is directly compared to the reviews of others using the sedan springs.

There isn't anything wrong with that but, I am sure you either:

1. Found someone who previously installed the setup and paved the way with good reviews.

2. Accepted the fact you were in uncharted territory and there was the possibility it could yield unsatisfactory results with the potential of completely having to redo the suspension setup.
