Hey car enthusiasts! So, you're looking to beef up your New Edge Mustang's handling, huh? Awesome! You've come to the right place. Today, we're diving deep into a critical upgrade: rear control arms. These bad boys are super important for how your Mustang handles, especially when you're pushing it through corners or just want a smoother ride. We'll cover everything from why you should consider upgrading, to the different types available, and even touch on the installation process. By the end of this guide, you'll be well-equipped to make the best choice for your ride. Let's get started!

Why Upgrade Your New Edge Mustang Rear Control Arms?

Alright, first things first: why should you even bother with upgrading your rear control arms? Well, the stock arms on the New Edge Mustang, while functional, are often the weak link in the suspension system, especially if you're planning any performance modifications. Think about it: these arms are responsible for controlling the movement of your rear wheels, and if they're not up to the task, your car's handling will suffer. When you upgrade your rear control arms, you're essentially: improving your car's handling capabilities, making it perform better, and giving it better stability while you drive. You're also improving overall performance, and how the vehicle responds to road conditions.

One of the main benefits is improved handling. Upgraded control arms are typically stronger and stiffer than the factory ones, reducing flex and deflection under load. This means your car will feel more planted and responsive, especially during hard cornering. You'll notice less body roll, more precise steering, and a general feeling of improved control. Trust me, it's a game-changer! Imagine taking a turn and feeling confident that your car will stick to the road. This upgrade can make it happen. You're also gaining better acceleration and a smoother, more comfortable ride. If your goal is a comfortable daily driver, upgraded control arms can help with that.

Beyond handling, upgraded arms can also improve your car's overall performance. Stiffer arms translate to more efficient power transfer, meaning more of your engine's power actually makes it to the ground. This is particularly noticeable during acceleration and can lead to improved lap times or better 0-60 mph times if you're into that sort of thing. Plus, upgraded arms often come with improved bushings, which further enhance handling and can reduce unwanted noise, vibration, and harshness (NVH). Who doesn't want a quieter and more comfortable ride, right?

So, whether you're a track enthusiast, a weekend warrior, or simply someone who wants to enhance their Mustang's handling and performance, upgrading your rear control arms is a solid investment. You'll be amazed at the difference it makes. It’s a worthwhile upgrade that can significantly transform your driving experience. By upgrading your Mustang, you are ensuring the car can handle any situation.

Types of Rear Control Arms for Your New Edge Mustang

Okay, now that you're sold on the idea, let's talk about the different types of rear control arms you can choose from. The market offers a variety of options, each with its own pros and cons, so it's essential to pick the ones that best suit your needs and budget. We'll break down the main categories to help you make an informed decision.

1. Adjustable vs. Non-Adjustable Control Arms

One of the first decisions you'll face is whether to go with adjustable or non-adjustable control arms. Non-adjustable arms are generally a more affordable option and are a direct replacement for the factory arms. They're typically made of stronger materials and feature improved bushings, offering a noticeable upgrade in handling and durability. However, they don't allow for any adjustments to your car's alignment.

Adjustable control arms, on the other hand, offer a range of adjustments, allowing you to fine-tune your car's suspension geometry. This is particularly beneficial if you've lowered your car or plan to do any serious track driving. Adjustable arms allow you to dial in the perfect alignment settings for optimal handling and tire wear. You can adjust the length of the arms to correct for changes in suspension geometry caused by lowering your car, and you can also adjust the pinion angle, which affects driveline vibrations. Adjustable arms are generally a bit more expensive than non-adjustable ones, but the added flexibility can be worth the investment for serious enthusiasts. Keep in mind that you'll also need an alignment after installing adjustable arms.

2. Materials: Steel vs. Aluminum

Another key consideration is the material used to make the control arms. Steel control arms are typically the most affordable option. They're strong, durable, and can handle a lot of abuse. However, they can also be heavier than aluminum arms, which might slightly affect your car's unsprung weight (the weight of the components not supported by the springs). But if you have the budget, aluminum control arms offer several advantages.

Aluminum control arms are much lighter than steel, which can improve your car's handling and acceleration. They're also often designed with more advanced features, such as improved bushing designs and better corrosion resistance. The downside? They're generally more expensive than steel arms. The choice between steel and aluminum depends on your budget and how much weight savings you're aiming for. If you're on a tight budget, steel arms are a great option. If you're looking for every performance advantage possible and don't mind spending a bit more, aluminum arms are the way to go.

3. Bushing Types: Rubber, Polyurethane, and Spherical (Rod Ends)

The type of bushings used in the control arms also plays a significant role in their performance. Rubber bushings are the most common type and offer a good balance of comfort and performance. They absorb road vibrations well, making them ideal for daily drivers. However, they can also deflect under load, which can slightly reduce handling precision.

Polyurethane bushings are a step up from rubber. They're stiffer and more durable, offering improved handling and reduced deflection. They also tend to last longer than rubber bushings. The downside? They can transmit more road vibrations into the cabin, which might make for a slightly less comfortable ride.

Spherical rod ends (also known as heim joints) are the most performance-oriented option. They offer zero deflection, providing the ultimate in handling precision and control. They're typically used in racing applications. The trade-off is that they transmit a lot of road noise and vibration into the cabin, making them unsuitable for most daily drivers. Choose the bushing type that best fits your needs, taking into account the type of driving you do and your comfort preferences.

Installation Guide: Installing Your New Rear Control Arms

Alright, you've chosen your new rear control arms, and now it's time to install them. Don't worry, it's not as daunting as it might seem! With a little bit of know-how and the right tools, you can easily tackle this project in your garage. Before you start, make sure you have all the necessary tools and safety equipment, including jack stands, a jack, a wrench set, a torque wrench, safety glasses, and gloves. Having all of these things will make the process easier and less frustrating. You'll also want to read and follow the instructions that come with your specific control arms. Here’s a general overview of the installation process:

Step-by-Step Installation

1. Preparation: First, safely lift your Mustang and secure it with jack stands. Make sure the rear wheels are off the ground and the car is stable. If you’re working outside, ensure the ground is level. Disconnect the negative terminal of your car's battery to prevent any electrical mishaps. Also, spray penetrating oil on the bolts of the existing control arms to make removal easier. This will help loosen any rust or corrosion that has built up over time.
2. Removal of the Old Control Arms: Locate the rear control arms. Use your wrench set to loosen and remove the bolts that secure the control arms to the chassis and the rear axle. You might need to use a breaker bar or some leverage to get stubborn bolts loose. Once the bolts are removed, carefully detach the old control arms.
