So, you're thinking about upgrading your Infiniti G37's brake calipers, huh? Awesome! The G37 is a sweet ride, and beefing up those brakes with some sport calipers can seriously enhance your driving experience. Whether you're looking for better stopping power on the track or just want a more aggressive look behind those wheels, this guide will walk you through everything you need to know about Infiniti G37 sport brake calipers.

Why Upgrade Your Brake Calipers?

Let's dive right into why swapping out your stock calipers for some sportier ones is a worthwhile upgrade. First and foremost, it's about performance. Sport brake calipers are designed to provide more consistent and stronger braking force compared to standard calipers. This is crucial if you frequently find yourself pushing your G37 to its limits, whether on spirited drives or during track days. The enhanced braking performance translates to shorter stopping distances and better control, making your driving experience safer and more enjoyable.

Beyond performance, there's the aesthetic appeal. Upgraded calipers, especially those with a vibrant color finish, can significantly enhance the look of your wheels. Imagine a set of bright red or blue calipers peeking out from behind your rims – it's a surefire way to turn heads and add a touch of personalization to your ride. Many aftermarket calipers also feature a more aggressive and sporty design, further contributing to the overall visual upgrade.

Another important aspect is heat management. Sport brake calipers often incorporate design features that improve heat dissipation. During hard braking, the brake pads and rotors generate a tremendous amount of heat, which can lead to brake fade – a phenomenon where the braking force decreases as the brakes get hotter. Upgraded calipers, with their enhanced cooling capabilities, help to minimize brake fade and maintain consistent performance even under demanding conditions. This is particularly beneficial for drivers who engage in track events or frequent mountain runs.

Finally, consider the longevity and durability of upgraded calipers. While stock calipers are generally reliable for everyday driving, they may not be up to the task of sustained high-performance use. Sport brake calipers are typically constructed from stronger and more durable materials, such as forged aluminum, which can withstand the rigors of aggressive driving and provide years of reliable service. This makes them a worthwhile investment for drivers who demand the most from their G37.

Understanding Brake Calipers: A Quick Overview

Before we delve into specific options and considerations, let's take a quick look at the basics of brake calipers. Simply put, brake calipers are the components that squeeze the brake pads against the rotors to slow down or stop your vehicle. They're a critical part of your braking system, and their performance directly impacts your car's stopping ability.

There are two main types of brake calipers: fixed calipers and floating calipers. Fixed calipers have pistons on both sides of the rotor, providing more even pressure and better performance. They are commonly found on high-performance vehicles and are a popular choice for upgrades. Floating calipers, on the other hand, have pistons on only one side of the rotor. They are simpler and more affordable, but they may not provide the same level of performance as fixed calipers.

The number of pistons in a caliper is another important factor to consider. Calipers with more pistons generally provide more clamping force and better braking performance. Sport brake calipers often have four, six, or even eight pistons, compared to the one or two pistons found in many stock calipers. This increased clamping force translates to shorter stopping distances and improved brake feel.

The materials used in the construction of brake calipers also play a significant role in their performance and durability. Stock calipers are typically made from cast iron, which is strong and affordable but can be heavy. Upgraded calipers are often made from lighter and stronger materials, such as forged aluminum. This reduces unsprung weight, improving handling and responsiveness, while also providing better heat dissipation.

Finally, it's important to understand the concept of brake bias. Brake bias refers to the distribution of braking force between the front and rear wheels. Ideally, the front brakes should handle a larger portion of the braking force, as the weight of the car shifts forward during braking. However, it's important to maintain a proper balance to prevent wheel lockup and ensure optimal stopping performance. When upgrading your brake calipers, it's crucial to consider the impact on brake bias and make any necessary adjustments to maintain proper balance.

Choosing the Right Sport Brake Calipers for Your G37

Okay, so you're sold on the idea of upgrading your G37's brake calipers. Now comes the fun part: choosing the right set for your needs and budget. With so many options available, it can be a bit overwhelming, but don't worry – I'm here to help. First, you need to determine your budget. Sport brake calipers can range in price from a few hundred dollars to several thousand dollars per set, so it's important to set a realistic budget before you start shopping. Keep in mind that you'll also need to factor in the cost of brake pads, rotors, and installation.

Next, consider your driving style and intended use. Are you primarily looking for better stopping power for everyday driving, or do you plan to track your G37 regularly? If you're a serious track enthusiast, you'll want to invest in a high-performance set of calipers with features like multi-piston design, forged aluminum construction, and enhanced cooling capabilities. If you're mainly looking for improved aesthetics and slightly better performance for street driving, you can probably get away with a more affordable set of calipers.

Another important factor to consider is compatibility. Make sure that the calipers you choose are specifically designed to fit your Infiniti G37. Check the manufacturer's specifications and compatibility charts to ensure a proper fit. You may also need to purchase adapter brackets or other hardware to install the new calipers. It's always a good idea to consult with a qualified mechanic or brake specialist to ensure that you're choosing the right parts for your car.

Think about the size of your wheels. Upgraded calipers are often larger than stock calipers, so you need to make sure that they will clear your wheels. Check the dimensions of the calipers and compare them to the available space behind your wheels. You may need to use wheel spacers to provide additional clearance. Some caliper kits are designed to work with the stock wheels, but it's always best to double-check before making a purchase.

Finally, consider the brand and reputation of the manufacturer. Stick with reputable brands that have a proven track record of producing high-quality brake components. Read reviews and do your research to make sure that you're buying a reliable product. Some popular brands of sport brake calipers include Brembo, Wilwood, StopTech, and AP Racing. These brands are known for their performance, quality, and durability.

Installation: DIY or Professional?

Once you've chosen the perfect set of sport brake calipers for your G37, the next step is installation. You have two options: you can tackle the job yourself, or you can hire a professional mechanic to do it for you. If you're comfortable working on cars and have the necessary tools and experience, you may be able to install the calipers yourself. However, it's important to be honest about your abilities and to proceed with caution. Brakes are a critical safety system, and any mistakes during installation could have serious consequences.

If you decide to DIY, make sure to follow the manufacturer's instructions carefully. Gather all the necessary tools and supplies, including a jack, jack stands, wrenches, sockets, brake fluid, and a torque wrench. Disconnect the battery before starting work to prevent any electrical accidents. Carefully remove the old calipers and brake pads, and clean the mounting surfaces. Install the new calipers and brake pads, and connect the brake lines. Bleed the brakes to remove any air from the system, and torque all bolts to the specified values. Finally, test the brakes thoroughly before driving the car.

If you're not comfortable with DIY brake work, or if you simply don't have the time or tools, it's best to hire a professional mechanic. A qualified mechanic will have the experience and expertise to install the calipers correctly and safely. They can also inspect the rest of your braking system and identify any other potential problems. While professional installation will cost more than DIY, it's a worthwhile investment for peace of mind.

No matter who does the installation, it's important to break in the new brakes properly. Follow the manufacturer's instructions for break-in, which typically involves a series of controlled stops from moderate speeds. This process helps to bed in the brake pads and rotors, ensuring optimal performance and longevity.
