After the input and reviews from a lot of you I have upgraded my wheels, tires, and springs to my G37xS Sedan!

Wheels/Tires Upgrade
Velgen Wheels 20x9 +35 & 20x10.5 +45
Hankook V12 245/35/20 & 285/30/20


Measurements with 20" Wheels: Floor to Fender

Front 28 1/2 "

Rear 28 5/8 "


Swift Springs Upgrade


Measurements with Swift Springs: Floor to Fender

Front 26 3/4 "


Rear 27 3/4 " ichh

 

I was expecting at least 0.8" drop in the rear but only got 1/2"

 

Who did the spring install? Did you get an alignment?

 

Royal Wheel & Tire in Arlington and no I didn't get an alignment yet since I got them done today but so far the car is not pulling to either side at all. The rear tires did camber in a little which i expected and wanted. The ride handles close to the sport suspension on the the G37 coupe. Now I have to be very wary of pot holes and bumps on the road with the 30/35 tires and swift spring combo

 

Nice. Good luck.

Curious how your specs will be.

 

Thanks I will post result if I get the alignment done

 

You'll probably settle a bit more, I wouldn't be surprised if it drops another 1/2". Looking good too!

 

I hope so man because 1/2 an inch is not enough lol
funny thing is the front dropped 1.75" that's even more than most people I have seen with these springs

 

I think it looks good (better) this way with the raked look.

 

Thanks

 

That doesn't sound right. Try the following:
1. Search the the forum for X springs and compare how much others have dropped. The Swift springs are linear so it shouldn't drop too much lower.
2. Check the box to make sure you received the correct item number.
3. Then I'd try to verify if they were installed correctly.

The Swift website shows the X should drop 1.3" in the front and 1.00" in the back. Part #4N907.

I did get the right item i already verified that. And the mechanic that installed them already installed the same springs on dragion's awd sedan.
I am still puzzled why the drop is so off, I will contact him and see what he tells me

 

My math says that your dropped 7/8 in the rear so thats pretty much spot on the specs for those springs in the rear

 

Well if you want to be accurate before it was 28.56" and now it is 27.81 so yeah it dropped about 3/4" which is still not as much as the 1" they are rated for...only thing i don't like is there is a 1" difference from front to rear

 

Nice choice in wheels and color. Looks mean on that blue slate
