Few questions. I'm going to purchase a 2013 g37 sedan, do I go with x, xS, S etc.? Also I'm already looking deep into modding before even getting the vehicle. As you can tell I'm very excited. What should I purchase first? Thinking of stillen g3. Also is there body kits available? Having trouble finding any for a 2013.

 

Welcome to the site, hopefully GoFightNguyen can chime in w/ his standard
welcome page w/ full lists of mods and a good plan of attack.
That said, unless you absolutely need AWD I'd go w/ a RWD S model, you'll find more mods available for RWDs and the S sedan has more performance upgrades than the XS versions. They come w/ big Akebono brake calipers LSD rear end, a slightly firmer suspension, nice sport bumper and side sills. There are some body kits floating around but not really sure about specifics. Most just look at front chin spoilers and rear diffuser kits. A lot of the RWD members that live in the snow belt just use summer tires until winter than switch to good snow tires rather than going w/ all -seasons year round, seems to be the best plan.
Good luck w/ your search and enjoy the site.

That's a pretty big question. Welcome to the forum, there's a lot of opinions regarding what model/mods to get/install.

It's hard to tell you what's best for you, the wisest decision would be to use the search function here on the forum to look up mods you might like to try. There's probably a DIY, a cost analysis, and a review for just about every part you might ever want to install. It sounds like you've done a little research, but you've gotta go deeper to get something solid enough to spend your hard-earned money on.

After all, the only thing worse than seeing your bank account after buying a mod, is seeing your bank account after buying a mod you hate.

Personally, I have an S, but that's because I live in texas, and have almost no snow in Houston. I also have a coupe, so that tells you how important "practicality" is to me. If you have snow, I recommend an X at least, but remember, there's no substitute for snow tires.

It's worth mentioning that the XS is a cosmetic package only. In the S (coupe at least, idk about sedan), a true sport package gets you stiffer sway bars, tighter steering ratio, paddle shifters in the automatic version, a sport front bumper, bigger rotors, bigger wheels, a limited slip differential, a rubber bushing between your diff and your driveshaft, better seat bolsters, aluminum pedal trim, and the coveted big brake kit. AFAIK, none of the performance mods are present in the XS. If you choose the AWD, you're leaving the Akebono brakes behind, as well as the stiffer sways and steering ratio.

As far as body kits go, there are a few options, look up Autokits X, Outkast Garage, Zele, JP Visage, Top Secret, Tommy Kaira, among others. The price of duraflex may be appealing, but I would avoid it.

 

buy whichever model suits your needs the best. buy whatever mods you like.

 

Whew, took me a while to find it.

Here's my generic response to new members who are looking to get into modding. It's a little overwhelming at first, here's a breakdown of the various mods:

Here's the cliff's notes version of most of the questions new members ask Version 2!

1. Everyone disagrees on which external mods look good. That being said, the popular mods people do externally are:
Body kits (IPL or Aero or Top Secret)
New wheels (Vossen, Stance, Velgen, VMR, Forgestar, Forgeline, and Enkei are popular brands), check threads to see if they'll clear your brakes instead of just posting up a wheel fitment thread.
Lights (people change the lenses to TSX lenses, paint the housings, delete amber corner, and add LED rings)
Fog Lights switched to HID (less useful in actual fog, but good for looks)
Carbon Fiber (most things are available in carbon fiber, VIS and Seibon are popular mid-price brands, fitment is always a concern, IGT, AIT, and Autokits X make great stuff too)
smoked lights (recently cause for instant inspection fail in Texas, YMMV)
Debadging
LED interior light swap (diode dynamics or other companies offer kits containing all the LED's you need)
Spoilers (front chin, rear decklid, rear wing type, roof mounted spoiler)
Diffuser (autokits x, other companies)
Plastidip (hideous, don't do it)


2. The best HP performance mod you can do is Forced Induction. These cars love boost, and any bolt ons (exhaust, intakes) will see only marginal HP boosts. However:
Cold Air/Short Ram style Intakes (K&N, Sillen, Takeda, R2C, Injen, Greddy)
As far as intakes are concerned, the two main types are long tube style, or short ram style. Short ram has the benefit of being simple to install, does not require bumper removal, and adds very nice aesthetics and minor sound changes)
Long tube intakes pull cold air either from very low in the engine bay, or from in front of the radiator. These typically see bigger hp gains, but require modification to the radiator shroud on occasion.
Intake Manifold (Motordyne, Z1)
Header (Fast Intentions Long Tube Headers, Z1 short tube, Stillen short tube)
High Flow Catalytic Converters (Fast Intentions, Berk, Stillen, among others)
Test Pipes (same companies as Cats)
Catback Exhaust (Apexi, Tanabe, HKS, Greddy, Borla, Fast Intentions, Motordyne, Magnaflow, Top Speed, others)
Tune (either dyno professional, or handheld tuner unit)
Grounding kits (DIY)
Forced Induction (GTM twin turbo, GTM twin super, GTM single super, Stillen Super)

3. Suspension mods
Sway Bars, biggest bang for buck mod, (Hotchkis, Cusco, Stillen, Eibach)
Front Tower Strut Bar (Cusco, GT spec, others)
Coilovers vs. Springs
Coilovers allow user to adjust drop exactly as needed, springs have 1 drop height
Coilovers allow user to adjust drop without changing spring compression (usually), springs do not
Coilovers and Springs may both require camber kits.
Various chassis braces (may not be compatible with whatever exhaust you choose)
Coilover Brands: Ksport, BC Racing, Megan, Tanabe, JIC, HKS, Stance, Fortune, KW, and Tein
Spring Brands: Swift, Eibach, H&R, others


4. Tires
Most dealerships have OEM Bridgestone Potenza tires for their sport models in a staggered fitment. The factory toe and camber specs tend to make very short work of the OEM tires, plus their tread rating isn't the best. The favorites on the forum as far as summer performance replacement tires would be:
Michelin Pilot Super Sports $$$$
Bridgestone S-04 Pole Position $$$
Hankook Ventus V12 Evo $$
OEM Bridgestone Potenza
Falken, Eagle, Etc.


5. Brakes
For 99% of your average Infiniti owners' driving, the OEM, non-sport brakes are perfectly fine. They still provide great stopping power. The other 1% are those that NEED the akebono big brake kit, for racing/track purposes. To that end, popular brake mods are:
Upgrade your non-sport brakes to sport brakes
Upgrade your soft rubber brake lines to stainless lines (technafit, stoptech, most others are a rebrand of one or the other, i.e. Z1 "premium" and "non-Premium")
Upgrade your rotors to drilled, slotted, or drilled + slotted.
This is worth taking a minute to discuss. The idea behind slotting or drilling your rotors is to great a channel that will "wipe" or move air to disrupt the breakdown/application of brake pad material to the rotor. Ostensibly, this prevents you from depositing more pad material than you break down, and ending up with juddery brakes and brake fade.
I've heard rumors or drilled+slotted brakes failing from the stresses of track, or race applications, and I'm going to caution you against going that route unless you just like the looks and don't plan on tracking the car.
Upgrade your rotors to premium aftermarket rotors (centric)
Upgrade your brake pads
Race Spec (squeal, lots of dust, not great breaking when cool)
Hawk HP+, Carbotech, Cobalt, Infiniti R-Spec, Project Mu
Street Spec (not as good bite as race spec, more brake fade, easier for daily driver)
Stoptech Street Performance, OEM pads, others
Flush your fluid (Motul RBF 600)
Welcome to the forum, watch your head!

 

Thanks Anthony, I bookmarked your reply^^ so I can just cut & paste when the need arrives

 

I updated the cliffs notes to incorporate a section dedicated to brakes.
