I have done a search and haven't found much on this minus the individual parts to switch. My question is that I would like really like the upgraded suspension/rims/brakes from the S. I was hoping to track this down mainly via junkyard/trade to keep the cost low.


My overall goal is after a year drop the Stillen SC and keep her til the wheels fall off.


However, from what I've read even the S's suspension and such may still be too soft to really handle the Stillen kit. So would be it better to just upgrade to something different or a more recent model year? Trading/ect would keep costs down. I also realize the awd makes it a little harder for parts. Really could use some input from someone who has done this or upgraded bigger. Really like the stock S rims. Thanks for the input!

 

I'll try to answer your questions one at a time, as always, if you have specific questions, you can probably find the answer in a dedicated thread.

It really depends which supercharger you get from stillen, I'm not sure what you mean by "handle the stillen kit", but plenty of guys use the stillen kit with stock suspension. The transmission would probably be the weakest link in a forced induction build.

Most people regard the big brake kit as more of a cosmetic change, yes it prevents fading and they work great, but most of us would probably get alone just fine with the regular brakes. Most of us don't ever track the car, so brake fade is almost a non-issue.

The suspension on any of the G's is a dual wishbone front, and a multilink rear. The big difference between the S is the tighter steering and stiffer sway bars. Aftermarket sway bars are still easily available and are generally held to be one of the best bang-for-buck mods for any Infiniti.

I guess it really depends on what you want to do. You should realize right now, the G37 is not, and will *never* be a drag racing champion. There are too many other cars that would make a better drag racing platform. You're right, the AWD makes it harder to find compatible parts, but they ARE out there.

If you're looking for something to go toe to toe with a Boss 302, you're in the wrong car, and would be better off with something with more displacement.

 

Remember the factory XS doesn't come with the big brake kit that the RWD S has. You're likely better off going with an aftermarket big brake it, unless you can find the OE Akebonos cheap.

 

Spot-on comments from GoFightNguyen.

 

gofightnguyen, appreciate the input. I understand this is not a coupe sport but really like the idea of the luxury sleeper so to say. I doubt I'll have it at the drag strip like some prior cars. However, I've always had a S model and made the suspension tighter from there usually with struts. Really like the 18's or 19's for the look and am curious about the stock brakes, last car had dual vented cross drilled brembo. I'm used to the twisties and this car just doesn't seem to hold the g's.

 

I have an x and have done the BBK and sways but the steering ratio still isn't like the S. Haven't SCd the car so I can't speak to that but if you're looking for steering response might be best to look at a S as opposed to an xs

 

Rex, did you get aftermarket tighter sways? With the BBK do you have the 17's or upgrade your rims? I understand still won't be the S because of the components and height difference but I have the x because I live in the snow belt. I wanted the SC just for a little extra fun. I really don't need the extra power for the twisties as it has enough. Problem is in the turns where I have been used to a lower car with stiffer suspension and larger rims the x just seems on the edge of flipping. That's really where I want to tighten her up.
With that being said, I am trying to see if anyone has:
1. Switched components from an x to an xS- possibly cheaper? Is this even worth to do?
2. Merely upgraded sways/added struts/rims(18 or 19) ect from the xS with better difference
3. With expectation that I am preparing for a SC kit prob to the 410hp, with the current tires/suspension I think with the TC off I'd be all over the place as it will revert 25/75 diff. At least in snow it does!

 

If you're going to replace your sways, don't just put OEM Sport sways on the car. That's such a half-azz measure, and besides IIRC only the rear sport sway will work on the AWD G... you need aftermarket to upgrade the front sway. Upgrade to any number of manufacturer options out there, because they're all pretty much the same. This will absolutely flatten the car in the turns, at which point your next major handling performance mod are 3-season tires.

The BBK won't fit behind 17" rims. Personally, I'm of the mind that unless you track the car, the BBK is 90% bling and 10% performance; even though I have the BBK and I have Auto-X'd the car a couple of times. I also think that if you want to take a car to the track, the G37 is the wrong car for that activity. Regardless of where people land on those opinion, there are two undeniable facts about the Akebono BBK: One, it's hella heavy, and two, it's a beautiful thing.

Snow belt schmo belt... It's just Cleveland, for pete's sake. What you need are snow tires.

A supercharger is a pretty significant prospect for just "a little extra fun". Unless you have money to burn, better off getting a different AWD car entirely, like a WRX, or a 335ix.

 

I really cant comment on the S suspension cause I have a just a X but and "had" the SC kit on my car and ripped a lot of cars, including a C63 "newer" and a handle for over mustangs"302" included. Granted these were al HW runs and GoFightNguyen is right at the track the car isn't he best because of the added wait of the Tcase and the SC really doesn't make GOOD power till upper RPMS. I did springs, and Sways on mine and it handle everything I tossed at it. But remember I had a custom tune and upgraded the Impeller and some other things also. STG 1 made 412 WHP STG2 made 457 WHP.

 

Again, it depends on which components you plan on switching. In the XS, the "S" components are almost only cosmetic. You get the looks of the sport model, with none of the components that make an S worth the money, IMO. The big brake kit would have to be swapped into an S, which has been done before, no problem. Aftermarket swaybars are always a good option, I don't have them personally (yet), but they are extremely popular around here. You won't regret getting them for driving in the "twisties." Sways alone will give you a significant ride and cornering difference, that body roll you're feeling will go away and you'll be able to carve corners a lot more tidily.
There are plenty of X and XS G37's with supercharger kits. Superchargers bring the power a lot more evenly than a turbo will (generally), and slipping isn't as much of a problem. Throttle control is the key here, which I'm sure you know. If you slip in the snow with stock power, then you'll slip with a SC. A supercharger may just require MORE finesse with the throttle, but the accompanying tune and an alert driver can put down power to a SC X or XS no problem.

Like I said before, sufficiently large forced induction platforms will cause wheel spin, it's a fact of life. However, you can mitigate that with good driving practices. With great horsepower comes great responsibility.

 

WTF, man? Bang Bang on your head

I'm not even going to talk to you again until you get sways. You're dead to me.

 

That's next on the list, I swear. Eibach, just shopping around >_>

 

Haha, you guys crack me up. Thanks for the input. Sounds like sways are the way to go. Plus going from 17's stock to 18's with smaller firmer sidewalls would help a lot. Obviously with the TS off I'm trying to spin the tires!

 

Not so much, actually, unless the change is dramatic... like from a 16" to a 20" wheel, and even then the 20" will be much heavier, which is a factor that comes with its own problems. It's more about the tire design, compound and tread than it is the sidewall. Put quality, 3-season performance tires on the car, regardless of wheel diameter, and the handling improvement will be huge. Same goes for snow tires and handling on snow & ice.

As for traction control... you turn it off if you want to maximize your launch from a dead stop (whatever your reasons ), or if you want to have a little oversteer fun on the ramps. And you absolutely turn it off for Auto-X. But for normal DD behavior, it's safer to just leave it on for those emergency situations.

 

On the street NO, at the track I was all over the place
