I recently acquired a used 2013 g37xs with 33k miles and so far I love it.
couple of things though I'm getting really poor gas mileage around 14 city. I've read here ,some owners get around 16-19 mpg city. and the other thing is the steering feel at highway speeds. whenever I reach around 70 mph the steering becomes really loose no feedback/light. anyone else have that happening.?




things to come
1. new intakes (I'm thinking k&n or stillen)
2. sway bars (suspension too bouncy for my liking)
3. strut bar (maybe)
4. exhaust system
5. suspension (bilstein)
6. maybe a throttle booster (still doing research on that)


I appreciate any feedback/input/suggestions from you guys.
and I'll post as I do the changes and post pictures as well
so wish me luck!!

 

Welcome to the site!
Do you have the original tires? if so they may need to be replaced, tires that are very worn will tend to get "floaty" at higher speeds, it could also be your alignment.
Bilstein AFAIK doesn't have any AWD sets. Look into Swift springs or KSport or Fortune 500 coilovers.

I have some crapy all season tires that I want to replace ASAP. And as for the alignment I'll definitely have to do one at my local mechanic.
Also thanks for the suggestions for the suspension

 

ditto!

welcome to the forum and happy modding!!
