Beefing up suspension
Everything looks good. The K.W and Eibach were made for each other. The Eibach sways will not kill your OEM endlinks. I ran them fine on my 2011 with K.W and never had any issues or ware issues at all. But my car was new with only 5600 miles on it when the Eibach sways were installed and my car being 2011 Infiniti might have changed the endlinks from 08-2010 model year.
However I would never go the Eibach K.W route again, let me explain why.
The Eibach sways are very good but also they are heavy. If you look into the application specs you will see the 370/G37 part numbers are the same.

Reasons why Eibach is not good for our cars is Eibach did not design there bars for our cars unlike Cusco! I will get to them in a min. Diameter: 32 mm

Having a bigger bar is not best as when you upgrade your roll bars it's to create balance. Remember an over stiff sway bar will keep the rest of your cars suspension from doing what it was designed to. Only reason you want to upgrade your bars is to dial out understeer!!
Our Cars for safety come from the factory designed to understeer so you don't oversteer your backend into a tree. However with the proper tires and camber settings you can get the car to oversteer a little and still have the car correct it self on the way out.
Making the car more Neutral is what you want and takes time and adjustments.
I would recommend Cusco, few reasons.
They are made in Japan, Cusco went out of there way to design and strong light weight sway bar that's fully adjustable for the G37.

As you can see the are not as big as the Eibach but made better.
Now Reason's not to go with K.W V1, V2, V3, ClubSpec)
Yes K.W will give you a smooth ride and is one of the best coilovers out there. (K.W made in Germany)
However I feel if you want to take your car to next level and you want to beef it up, go with ( HKS Hyper Max 4 or Cusco Street Zero S )
Both made in Japan and designed to work with G37.
I feel K.W, Eibach and H&R work best on car like BMW and Audi. H&R if you look at there product line they make a lot of nice coilovers for BMW and Audi but our cars get a crap made kit.
So that's just my 2 cents you can do what you want, but wanted to put that out there.

I bought my first G37S a few months back and I wanted to beef up my suspension. I used to own a 2002 Firebird with beefed up suspension and I loved it. I love taking those curves like nobody's business. Why? I don't know myself. Here are a list of parts I'm planning to buy and have installed in my car. What do you guys think about this?
Eibach front and rear sway bar set
KW Variant 3 Coilovers
GT Spec front subframe tie brace
GT Spec front strut bar
GT Spec fender braces
GT Spec front lower tie brace
GT Spec rear lower ite brace
GT Spec four point mid chassis reinforcement brace
GT Spec rear 6-point subframe brace
Spacers
SPC Camber Arms kit
SPL Pro front endlinks
For performance I'm planning on getting
Berk HFC
Invidia Q300 Exhaust
Thank you in advanced for the opinions.

Wow, that's some good knowledge. Looking at it now, I just might go with the Coilovers made by Cusco and that's it. Maybe the strut bar and that's it. Thank you very much for everyone's opinion. Definitely an eye opener. Right now I only have less than 200 miles on the car. I won't be driving it until February so selling the shocks and spring with only couple hundred miles might be an easy sell.
