I'm looking to upgrade mine based on the posts I've read here on guys installing G37 RWD RSB on their G37x's but wanted some confirmation if the 370z RSB will install and fit without any problems other than buying new bushings?

Basically, Is the 370z RSB the same on a G37 RWD RSB Sway bar?

 

Supposedly it is. I have one sitting around that I need to install still.

 

lol. I think I read your post in the other posts. I figured you already installed your's already hah.

Can anyone else chime in?

 

I just installed it on my 2012 G37x. I had to drop the muffler and sit it on a cinder block to get the new sway bar in. The OEM one came out without dropping the muffler. Make sure you install it with the car at ride height (up on an alignment style life or drive-on ramps). It handles great and it is stiff without being harsh. Pair it with the GTSpec rear lower tie and rear subframe braces and get thicker 245/50/R17 tires.

 

Thanks! The step where I have to use a lift or a ramp. If I don't have either can I substitute by resting my rear wheels on a set of old rims? I'm assuming the suspension needs to be loaded for it to be installed?

 

Correct. The suspension needs to be loaded as it does with the installation of the rear lower tie brace. Whatever you can do to be able to get under the car with the suspension loaded. Ratchet, 10/12/14mm sockets, a short and long ratchet extension, and some type of safety goggle as rust will get in your eyes. You will need new bushings if you didn't get them already as well as clamps. I picked up a silicone based plumbing grease from Lowe's for $3.50 that is waterproof and can handle temps up to 400F. Make sure to apply a liberal amount on the side of the bushing that makes contact with the sway bar. You can torque the bolts at ~40lb/ft (50nm). You will have to drop the exhaust from the back not from the middle. Two hanger bolts hold each muffler on and then another hanger bolt a little ways towards the center of the exhaust system on each side. This is a good time to polish your exhaust tips I had some rocks stuck in the plastic covering that went under where my spare tire was, so I removed the bolts and got the gravel out.

 

What are these clamps you speak of? The D-Brackets that mount the bushing to the underbody? or the clamps that hold the muffler to the y-pipe?

 

The brackets that mount the bushing to the underbody. You can see the part numbers here after clicking on each item: 2012 Infiniti G37 Sport Stabilizer Bar & Components

If the bar you are getting doesn't already come with them, then you will need two 54613-JL01B and two 54614-EG000

 

So just to confirm a 2009-2012 370Z sway bar does fit a G37? No other brackets required

 

bolts right up, just need to use the 370z bushings as your oem ones are too small to fit it. Mine came with the bushings, brackets and end links and was purchased used off ebay.

 

Did you feel any oversteer after install? I did this upgrade today and felt some on my quick drive to work from the shop. Is this normal? I have the stock front sway on.

 

I have all the same mods that post has but 245/40/19 tires and I would say the car feels more neutral as the understeering tendencies were reduced. Although when I was running Potenza S04's the car handled great. Now with all seasons it isn't nearly as sharp.

 

Hi, can you confirm if the RWD Rear sway bar fits your AWD sedan ?
Thx.
