Review of the Best Coilovers for G37 Coupes & Sedans

The Infiniti G37 has always been a car that handles well. Even though it’s slightly on the heavier side, it feels well planted and composed.

However, if you want to flick it around corners without feeling its weight, we recommend installing a set of coilovers.

With the right set of coilovers, you’ll be able to unlock the true handling potential of your G37 coupe or sedan.

Coilovers also give you the option to lower your ride height. Doing this correctly will significantly improve stability and steering response.

The way G37s look after being lowered is the best part though. There’s something about lowered G’s — they’re real head-turners.

Improved handling and better looks with one upgrade are a win-win in our books. Combine that with some wider wheels on your G37, an aftermarket exhaust system and supercharger or G37 specific turbo kit, and you’ll be smokin’ supercars all day.

In this guide, we’ll go over the key points you need to know before going ahead with this upgrade. After that, we’ll review the best G37 coilovers you can buy.

G37 Coilover Compatibility

When you’re on the lookout for Infiniti G37 coilovers, you’ll notice that some of them suit either the coupe or sedan, while some work for both.

Mechanically, the suspension setup on both cars is almost identical. Surprisingly, the Infiniti G37 coupe weighs more than the sedan.

The coupe is roughly 4 inches shorter, 2 inches wider and 2.5 inches lower in comparison. However, both cars have the same 112-inch wheelbase.

That said, the only factor you need to consider when it comes to coilover compatibility between the G37 coupe and sedan is spring rates. The same applies if you’re upgrading to lowering springs.

The G37 coupe typically requires a stiffer/higher spring rate compared to its sedan version due to the weight difference. Not many people will notice the difference but if you want the best possible ride or are planning to track your car, it’s worth getting right.

Most coilovers mentioned in this list are interchangeable between the coupe and sedan. The best part is that many manufacturers offer the option of selecting the spring rates of your choice.

Monotube vs Twin Tube Dampers

Coilovers are available with two types of dampers;

1. Monotube
2. Twin-tube

Monotube dampers are the most common. That’s mainly because the design is a lot simpler and durable.

As the name suggests, monotube dampers have all their components housed within one tube. It contains a shell that works as a cylinder. This cylinder contains oil and gas that is separated by a free piston.

The main advantages of monotube dampers include:

• Larger pistons for more stability
• Higher oil capacity
• Less prone to cavitation (when oil and gas within the damper gets mixed and causes a severe loss in performance)
• Resistant to extreme temperatures
• Easier to manufacture

Twin-tube dampers, on the other hand, have two cylinders — one on the inside of the shell case and the other which houses the piston valve. Twin-tube dampers don’t have a free piston that separates the air and fluid.

Even though they’re unconventional, twin-tube dampers have their advantages. Some of them include:

• Very comfortable ride
• Less friction on the seals
• Lower gas pressure

Spring Rates Explained

Spring Rate is a very popular unit used to describe how soft or stiff a spring feels. This term is commonly used in the world of G37 suspension upgrades. This is because it provides an accurate idea of how your car will feel with a certain set of springs/coilovers installed.

You’ll come across spring rates denoted as either “10k” (metric) or “560” (imperial):

• 10k = 10 kilograms of force needed for 1mm of compression.
• 560 = 560 pounds of force needed for 1 inch of compression.

If you read an Infiniti G37 coilovers review online, you’ll come across both these units being used in many places.

Here’s a spring rate conversion formula to make things easier: Kg/mm * 56 = lb*in

How it works: 10 kg/mm * 56 = 560 lb/in

Spring rate selection is subjective. While most people do, you don’t have to run stiffer rates if you’re into motorsport and vice versa.

If you visit a drift event, you’ll find that a lot of enthusiasts like their setup super-stiff while some prefer a softer setup to get the rear end sliding with ease.

However, most coilovers come with preset spring rates that work fine for most uses. It’s up to you to select which one fits your needs.

In our view, the best spring rates for an Infiniti G37 are:

• 10K Front 8K Rear: For comfortable daily driving
• 12K Front 10K Rear: For spirited driving and occasional track use

These monotube coilovers have 30 levels of damping adjustments with easily adjustable tuning knobs. This is useful if you occasionally tweak your suspension setup for different applications.

The first thing you’ll notice about Fortune Auto’s 500 series coilovers is how great they look. Not that it makes any real difference but if you’re into aesthetics and shiny parts, you’ll like these. More importantly, they perform even better than they look.

Fortune Auto has gained some serious street rep when it comes to coilovers. You’ll come across many Infiniti G37s fitted with these. The 11K front, 8K rear spring rate is very close to stock and it’s quite comfortable for road use.

These coilovers are equipped with what Fortune Auto calls “Digressive Piston Technology”. The purpose of this feature is to make your G37 handle irregularities and bumps, regardless of your speed. As a result, you’ll have more control over the car.

If you happen to live around Fortune Auto’s main facility in Richmond, Virginia, you can easily get your 500 Series coilovers revalved or rebuilt.

Megan Racing EZII

Manufacturer: Megan Racing

Construction Type: Monotube
Damping Adjustment: 15 Levels

Upper Mounts: Included
Suits: Coupe
Warranty: 1 Year
Buy On: Amazon | Enjuku Racing

Megan Racing’s EZII coilovers are an affordable, entry-level coilover setup for your G37. They are often compared with the ever-popular Tein Street Basis Z coilover kit because they are very similar in terms of price and quality.

These coilovers have a single-cylinder (monotube) design with 15 levels of damping adjustments. This is more than enough for street use.

Besides that, you get the same ride height adjustment you can expect with all of the coilovers on this list. Rubber dust covers protect each damper piston from dirt and debris. The build quality and overall performance is more than adequate considering the price.

This setup is ideal for G37 owners who want to try coilovers. You can get a feel of what they’re like, and upgrade to a better set in the future if you need to.

Revel Touring Sport

These coilovers come with a combination of linear and progressive springs that go very well with their 10 front and 8k rear spring rates. Overall, the ride is extremely complaint.

You can still lower your ride height by a good 2 inches to get rid of that wheel arch gap.

Each Touring Sport coilover uses a monotube damper with large piston valves and a higher oil capacity than most other coilovers in this list. This allows for consistent performance even under harsh conditions.

The Touring Sport coilovers by Revel are also backed by a 1-year warranty. All in all, a great deal for the price.

Stance XR1

Manufacturer: Stance
Part Number: ST-Z34-XR1

Damping Adjustment: 16 Levels
Spring Type: Linear

Stance’s flagship product — the XR1 is a great example of exceptional manufacturing quality. Being able to incorporate so much technology into a mid-entry level setup is commendable.

With these coilovers installed, your G37 will be glued to the tarmac and you’ll experience firm and confident handling through corners. This is achieved thanks to heat-treated Chromoly steel piston rods and digressive valving — similar to what you see on Fortune Auto’s 500 series coilovers.

Even though these are single way, 16 level adjustable coilovers, you won’t feel limited. The adjustment levels are extremely accurate and provide all the customizability you need.

Ksport Kontrol Pro

Manufacturer: Ksport
Part Number: CIN020-KP
Construction Type: Monotube
Damping Adjustment: 36
Spring Type: Linear
Upper Mounts: Included
Suits: Coupe
Warranty: 1 Year
Buy On: Amazon

Ksport’s Kontrol Pro is a well known, cheap set of Infiniti G37 coilovers. Just like Megan’s EZII and Tein’s Street Basis Z, they have a very attractive price tag and deliver just about everything you’d expect from a coilover kit in this price range.

These coilovers come with 36 levels of damping adjustment which is very generous, considering that they are entry-level G37 coilovers. Once installed, you can easily lower your ride height without having to change the compression level.

If you’re looking for long term reliability on a budget though, the Tein Street Basis Z coilovers are a better choice.

Tein Street Basis Z

Manufacturer: Tein
Part Number: GSP92-8UAS2
Construction Type: Monotube
Damping Adjustment: None
Spring Type: Linear + Progressive
Upper Mounts: Not Included
Suits: Coupe | Sedan
Warranty: 1 Year
Buy On: Amazon

From a budget standpoint, Tein Street Basis Z are the best value coilovers for G37 coupes and sedans. It’s the only entry-level setup that is tried, tested and admired by many Infiniti and Nissan enthusiasts.

Utility wise, they’re somewhat limited. For example, you won’t get pillowball mounts or any top mounts for that matter. Fitting these requires the reuse of your OEM mounts. Besides that, you won’t have any damping adjustments either.

However, none of that really matters a lot on a set of budget coilovers. They work just the way they should, are simple, and hassle-free.

If your goal is to lower your G37, make it handle way better than stock while saving money for more G37 mods, look no further than Tein Street Basis Z.

Our Favourite Infiniti G37 Coilovers

The good thing about coilovers is that they’re all mechanically quite similar. However, it’s the small details that make a few of them stand out. Remember that any modifications you make will affect your Infiniti G37’s insurance premium, so it’s worth getting a quote first to know what it will set you back.

In our view, these are the best coilovers for G37 sedans and coupes that you can buy right now.

Cheap G37 Coilovers: Tein Street Basis Z

Tein coilovers have the budget recipe just right. They focused their manufacturing efforts on what’s most important and omitted things that you can do without.

We really love this minimal setup and would recommend it to anyone who’s on a tight budget and wants that “OEM+ feel” but doesn’t want to lose out on quality.

High-Performance G37 Coilovers: Fortune Auto 500

If your G37 doubles as a daily driver and track weapon, this is the best set of coilovers you can buy.

A hand-built coilover kit backed by a 5-year warranty that’s priced so low is a total steal.
