Hey, new to the forum.

I had my G37x coupe for a year and I’m finally looking to get it tuned and add some test pipes to the situation. I’ve already installed the sport brakes and added a long arm intake.

my biggest concern is that I live in NYC and I wanna ensure that my suspension/ steering will be able to handle such power.

 

With just bolton's, you're fine. NYC roads will eat a sport suspension, keeping it stock will keep you driving longer.

if you do wanna mess around with suspension. Swaybars & endlinks are biggest bang for $$$. Coilovers after that.
Could convert to the sport steering rack if you're into a project

 

Boom. Call it a day. Upgrading the rear sway bar on an AWD G37 will help the handling immensely.

 

What’s the best one you recommend? Along with some links?

 

If money is no option, the Hotckis ($300 or so) set-up is a great option for a front and rear sway bar replacement and I run the MOOG endlinks with the zerk fittings so I can re-grease myself. If you want to literally get the best bang for the buck, pick up any rear sway bar from a RWD G37 or 370Z; along with the matching bushings. Cost all of $100-110 and you'll achieve the better handling you're looking for.

The front sway bar currently on your can is pretty thick and might be as thick as the Hotchkis one (maybe 1-2mm difference). Adding a RWD rear sway bar from a G37 or 370z takes your rear sway bar thickness from 17-18mm to 22+mm; only 2mm smaller than the Hotchkis one if memory serves. You can do some extra searching for a NISMO Z rear sway bar and come away with a 23-24mm and match that of the Hotchkis I believe. Basically, achieving the same rigidness for a 1/3 of the price. You are sacrificing the ability to dial in if you go the cheaper route since there's only one hole option so if there's any plans of autoX or something go the Hotchkis route.

 

@Moneymandann I also agree with RMB5190. Hotchkins sways, and Moog Endlinks and you set. I also have Tien Flex Z's and i have not had to adjust dampening. I put on all three the same day and felt a world of difference on our terrible NYC streets. Just make sure you avoid the potholes and other driving obstacles in the street. If you shop around now, you might be able to get some black friday deals for some of the parts.

Best of Luck and see you around!

 

If your into going to a junk yard (and can find a rwd g) I paid literally $20 for my sway bar. Found a sport and was on it the next day, best thing I could have done
