We all know there are many topics and posts. And options seem to be very limited, and I have not read anything definitive. But as of today regardless of cost, what is the best possible option? Experiences, opinions, suggestions... Thanks.

 

Get a big fat sway bar for (at the least) the rear. The stock one is thin. I got the Hotchkiss set and the difference is so palpable I think it's the overall value-added mod for our cars (with RHFCs coming in at a close 2nd).

 

Best possible mod = Leave it stock

 

I've never considered the effect of RHFC's on the suspension attributes, lol. But yes, the rear sway bar is a HUGE upgrade that you will notice immediately, in a good way.

There is definitely room for improvement, especially on the AWD suspension.


I would recommend going with a progressive lowering spring and rear sway bar combination. I have Eibach springs and find them to be a good balance of performance and ride comfort, but the Swift springs are also currently being tested and those have good reviews as well (They are about a month away from production). For the sway bar I'd recommend purchasing a RWD sway bar for an OEM piece that doesn't require maintenance greasing, or you can go with an aftermarket option that will need to be regularly greased to prevent it from squeaking. The OEM RWD bar will provide a noticeable improvement, but the aftermarket bar will provide adjustability and additional stiffness, if desired.

There isn't a great coilover option for the AWD G in my opinion. The BC coilovers have the notorious hit or miss clunking and the Fortune Auto coilovers are OK, but have not been on the market long enough to see how they fare over time. Ideally, KW would have an offering for us, but this is not the case.

 

I just purchased a 13 G37 X Sport...it has 19 in sport wheels...I assume it has the same rear sway bar as the RWD sport....I have all the GT spec Bracing and Tannabe exaust from my previous car...the Tannabe will not work on the all wheel drive....I have not analized weather any of the GT Spec bracing will fit as well. Probably will have to leave this car stock...


UP DATE..The Tannabe exaust axel back does fit...GT Spec bracing fits as well..changed tires to Pilot Super Sport 245 40 19..nice fitment... also added Hotchis sways front and rear...handling is great..

 

The AWD, whether sport or not, does not get the larger sway bar.

 

I'm in no way an X suspension expert, but.....you could look into Koni inserts if you dont want to go the coilover route. Its not cheap, but its not really out of line with the cost of coilovers.

 

That is an interesting idea and something to consider. Right now I am happy with the OEM Tokico shocks/struts, but I will keep this in mind if I have any issues down the road.

 

I've been wondering, why doesn't the oem sway bar need bushing greasing?

 

The OEM bushing is rubber and the aftermarket bushing is polyurethane.

 

So i guess in terms of lowering there is not many options besides the Eibachs or low quality coilovers as of now.

 

I have KSport Coilovers on my '11 G37xs from what I read before purchasing the quality is good. Please correct me if I am wrong on the quality

 

KSport is a budget coilover, with a hit or miss reputation.

 

I wanted to do coilovers not springs so I had a tough time finding coilovers for awd. Somebody recommended HSD but can't seem to find coilovers for G37xs. I am open to other recommendations

 

Fortune 500s seem to be the best available option currently for the AWD Gs.
