Yes, part numbers for the bushings/hardware please!

 

Looks like the rear sway is definitely a good upgrade for AWD models! To keep things simple I am thinking to just go for the stock RWD sway. Does anyone know if it would be a lot worse than aftermarket ones?

 

Ok, as requested the Nissan part # is 54613-JK01A. MAKE SURE YOU ORDER 2!!!! These will be the 24mm bushings. The X comes with bushings designed to fit on a 17mm bar. That will be all the hardware you need for the install (aside from your new bar of course). The new bushings fit inside the same brackets as the old ones did.

As for NCNC 's question... the rwd bar will cartainly be a considerable upgrade from the X bar. However, it will be less stiff than the Stillen bar. 30% less if the Stillen bar is on the softer setting and 70.4% less if the Stillen bar is on the stiffer setting.


BTW you will need the new bushings regardless of whether you get the Stillen or RWD bar.

 

Philip9869 - did you have to lube any of the bushings during the install?

 

Nope. Just pop them on the bar and install. In a different sway bar thread I thought I saw someone say that they got aftermarket bushings with grease fittings... but I figured the Nissan ones were good enough. Haven't had a squeak out of them either.

 

Did anyone find out about the coupe by any chance?

 

The rear sway should fit the AWD Coupe. I will be installing the stock RWD rear sway and will post the result here. Hopefully everything will turn out ok.

 

I finally had the stock RWD rear sway installed on my AWD Coupe! Yes, it fits, and same as the sedan the only other parts required are two bushings.

Ride quality is pretty much the same as before. Extra bumps/vibrations transferred to the cabin from the stiffer bar are very minimal so I believe this shouldn't be of a big concern to many people. In terms of handling, I can feel that the rear is now tighter so cornering paths are a bit more precise and predictable. The car seems a little more stable too when going over certain bridge joints.

I would recommend upgrading the rear sway even when we cannot change anything for the front. The extra stiffness on the rear really helps improving the handling.

awesome!
Is there anything to do with the front?
it definitely doesn't effect the awd?
And how come you didn't go for the stillen bar?

 

According to my research here currently there is no mod available for AWD G37's front sway bar so nothing can be done yet.. By changing the sway alone I don't think it would affect the AWD system. Since I'm not an expert in this I'll let the more experienced people here to answer this.

Initially I struggled between the stock bar vs. aftermarket ones too. My driving style is not that aggressive and I'm afraid that the aftermarket bar would be a bit too stiff for me. Also, because this is my first car mod I have decided to stay on a more conservative side. After some driving with the stock RWD bar I think I can tolerate a bit more stiffness so my guess is that an aftermarket one would be ok to many people.

sounds good, thanks a lot!

 

has anyone (with the x coupe) gotten just the rear bar from hotchkins or eibach??? i know its definitely possible with stillen and want to weigh my options. thanks guys

 

I haven't seen anything about anyone getting just the rear bar from Hotchkis or Eibach. They will of coarse fit, but you will probably just have to special order them just like you would the Stillen bar.

BTW sway bars have absolutely no effect on the awd system and if you want to stiffen up the front a little bit you can get a strut tower brace. I got one for my car and it makes a little difference. Nothing drastic like the sway bar, but it looks nice! Pics in my garage if your interested.
