Whats up y'all? I am looking to start making some mods to my suspension ASAP! I am currently stock on a 13 g37x Sedan, she is my daily. I know that I want to get the Hotchiks sway bar set (front n rear) but am debating if I should do bushings and subframe collars at the same time? My only concerns are that I don't want to increase NVH or ride harshness too the point where it can be annoying for me or others in the car. As I do live in Boston (Roads aren't the smoothest) and I do put clients in my car a lot. IF it weren't for the fact that I have a lot of clients in my car I wouldn't care about the harshness of the ride. Below I have listed the parts I am contemplating and some questions / concerns. Thank you in advance for any input, it's greatly appreciated!!!

Please dont tell me to search as I have searched all through the forms and online / youtube for this topic, but I'm still uncertain with the info thats out there. Would love to hear from people that have experience with these upgrades or others similar.

Some of my questions are:
- Is it worth to upgrade to poly bushings even though mine seem fine at the moment?
- I think the NVH will be fine (especially since I just ordered a FI CBE) but really curious as to ride quality with poly bushings vs stock????
- Ride quality stock vs subframe collar?
- I can't find a bushings upgrade kit for the front, do they not make them? do we not need them?
- I wonder how the sway bars will act with the different settings / what is best? (The rear sway bar is 3 way adjustable)

 

I just dropped my car off to an auto body shop to get my bumper repainted and picked up a new camaro v6 for a rental. And let me say that the camaro handle soooo much better than my car. If sway bars n bushings can make my G feel even close to the camaro, I'm all over it!

 

poly will last longer but are more harsh than rubber. 30% more if that doesn't bother you then you'll love the car feel and feedback.
