I've searched and searched here for this writing "4WS" every way possible but no luck.


I recently bought a 2009 G37S sedan 6MT (why anyone would own a non 6MT version of this is a topic I'd love to argue later about!) and I recently discovered this model was the last (or only?) year to be offered with 4 wheel steering. Makes sense why the steering felt "off" but I probably would have reconsidered buying this if I had known.


My question is: does it having 4WS effect which suspension/wheels/tires I can put on it? and to avoid starting a whole separate thread, can anyone recommend a decent tire setup for 20x8.5 wheels? need rain friendly and this is my daily so will never be tracked. Thinking Toyo T1 for around $650 / set. anything else to consider?


Will be installed by a local shop as I have no tools or space to do it myself.

 

I wasn't even aware there was a version of the G37 with 4 wheel steering... interesting.

 

I researched this car quite a bit while considering this over a TL-SH with 6sp and I wasn't aware either til I saw a light on the dash I didn't recognize during startup. Reviews on the system were mixed and it was done away with after 09 on this car but looks like it's coming back according to Infiniti website.

because, the wife said no...

 

My wife can't drive MT.

Keep your pimp hand strong

 

i think you are talking about '4was' four wheel active steering. there is no problem lowering cars with it. only thing that you cannot install are some chassis stiffening bars due to the location of the 4was motor.
also if you are getting a rear camber kit after lowering, i suggest the spl over the spc as the spl was designed keeping the 4was cars as well in mind.

 

Thank you. That is very helpful. No idea what the spl or spc is but will research it. Thanks!

 

SPL and SPC are the go-to brands for aftermarket parts like camber arms and end-links. There are others, but these two get lots of love on this forum. SPL products are kind of $$$.

IIRC, back when i was originally targeting a '09, I remember coming away with the impression that 4WAS was problematic with the fitment of aftermarket catbacks. Right or wrong... IDK. Something to reasearch, however.

 

I unfortunately have an X which I regret, but the lady's BMW is a proper 6 speed and rwd. It's one of the many reasons why she was the perfect girl for me.

 

I've got the 4WS...not much to it really. Heck I even installed the camber bolts.

I installed the SPL rear camber arms, RWD aggressive wheels, Fast Intentions RWD catback, and RWD coilovers. So it looks like the only aftermarket limitation is one stiffening bar and the toe arms.

If you look under the rear of the car, you'll see it.

Now the wheels you are looking at, 20x8.5 seems small. What are the offsets? I assume you can pull off a 245 size tire.

 

I don't have an exact wheel in mind. Im likely gonna go with TSW something as I like many of their designs and no amount of saving will ever get me to purchase my dream wheels by Rennen. I need all 4 to be the same width so I can rotate them appropriately and didn't know / research the widest I can go upfront....... I've seen some people listing 10.5 inches up front but didn't mention mods needed.

 

Your factory sport rims are staggered by a 1" difference. Seems plenty appropriate, irrespective of wants vs. needs.

 

Bringing this back from the dead.

To answer the question: No it will not impact the drivability of the car.
However you want to make your Toe and Camber are adjustable and want to make sure you know some alignment buddies.

The car relies heavily on the steering angle sensor so if the steering wheel is off it will affect your rear steering. If an alignment is done a proper check of the steering angle sensor is a must (needs to be done with the scan tool and reset if off)

The rear spring buckets are slightly longer so True Coilovers with the intention of deleting this arm will require custom since the aftermarket arms will be hanging off by a few threads.
The rear camber arms are different as well, I ran into the issue where the arm was too long and fully collapsed only gave me -1.5 camber.
The rear SPC toe bolts are too short. Longer bolts need to be bought, I found Audi A4 bolts with G37/370z shims works perfectly.

4WAS or not the V36 chassis needs arms for proper lowered angles. This is the same case with the 4WAS however it becomes a pressing matter with the 4WAS. Worse part is the stated above.

 

@BULL Would you happen to know if regular lowering springs like the ones Eibach makes for the G would fit on these 4was cars? Also I'm trying to find some oem type shocks/struts for the rear, but everywhere I go says not for 4was. Any idea if maybe they'll work on a 4was car even though they're not designed for them?
Thanks in advance!

The Sport tuned suspension on these cars came in the form as upgraded OEM parts. Usually many aftermarket replacements aim for "sports equivalent" or better feel. So Swift and shocks as well as coil overs will fit.

When looking into arms it's best that you look for something with quite a range of adjustability. A set that I got for a G37 ends up being too long when fully collapsed giving me a -1.9 of camber at most.
FYI any type of lowering will send your rear toe to Japan. Standard bolts wont work, you'll need to mix a combination of two cars to get a toe bolt setup that will work.
You'll have to remove the rear rack to wallow out the holes for the toe kits. You could get adjustable rear buckets or full coil over with a toe arm. Other than this you'll be suffering from a negative camber for you to maintain a 0 toe in the rear. The camber arms affect the toe and viceversa. Many times a nicer camber angle unbalances the toe.

In the front is ALL the same, the 4WAS actuator is in the steering column.
