OEM Rims vs. Aftermarket Rims

When it comes to choosing rims for your car, you have two primary options: OEM (Original Equipment Manufacturer) rims and aftermarket rims. Each type has its own set of characteristics and considerations. Let’s take a closer look at understanding OEM rims, their benefits, and their drawbacks.

Understanding OEM Rims

OEM rims are the wheels that come pre-installed on your vehicle from the manufacturer. They are specifically designed to meet the requirements and specifications of your car. OEM rims are often made by reputable manufacturers and are built to function optimally with your vehicle’s suspension, braking system, and overall performance. These rims are typically made from high-quality materials and undergo rigorous testing to ensure durability and safety.

Benefits of OEM Rims

There are several advantages to choosing OEM rims for your vehicle. Firstly, OEM rims are known for their high quality and reliability. They are designed to seamlessly integrate with your vehicle’s specifications, ensuring proper fitment and optimal performance. OEM rims also offer peace of mind, as they often come with warranty coverage provided by the vehicle manufacturer. This can be beneficial in case of any manufacturing defects or issues.

Another benefit of OEM rims is their compatibility with your vehicle’s existing tire pressure monitoring system (TPMS), hubcaps, and other components. This ensures that the overall aesthetics and functionality of your vehicle remain consistent. Additionally, OEM rims usually retain the resale value of your vehicle, as they are considered the original equipment for your car.

Drawbacks of OEM Rims

While OEM rims have their advantages, they may not always offer the customization options and design variety that aftermarket rims provide. OEM rims are often limited in terms of visual appeal and unique finishes. If you’re looking for a specific style or finish to enhance the aesthetics of your vehicle, aftermarket rims may be a better option.

Another drawback of OEM rims is their availability. Depending on the make and model of your vehicle, finding OEM rims that suit your preferences can be challenging. In some cases, OEM rims may be exclusive to certain vehicle models or trim levels, limiting your options.

Additionally, OEM rims may be heavier compared to certain aftermarket options. The weight of the rims can affect the overall performance of your vehicle, particularly in terms of acceleration and handling. If weight reduction is a priority, aftermarket rims specifically designed for weight reduction may offer a better solution.

When deciding between OEM rims and aftermarket rims, it’s important to consider your specific needs and preferences. While OEM rims provide reliability and compatibility, aftermarket rims offer greater customization options and potential weight reduction benefits. Assessing factors such as aesthetics, performance, cost, and availability will help you make an informed decision that suits your car and personal style.

Choosing Aftermarket Rims

When it comes to upgrading your vehicle’s rims, aftermarket options offer a wide range of choices that can enhance both the aesthetics and performance of your car. In this section, we will explore the various aftermarket rim options available, factors to consider when choosing aftermarket rims, and the impact of weight reduction on performance.

Exploring Aftermarket Rim Options

Aftermarket rims provide vehicle owners with a plethora of options to customize their cars according to their preferences and needs. Unlike OEM rims, which are the original equipment manufacturer’s standard rims, aftermarket rims are produced by third-party manufacturers. This allows for greater flexibility in terms of design, materials used, and customization options.

When exploring aftermarket rim options, you’ll encounter a diverse range of brands and styles to suit different tastes and vehicle types. Some popular aftermarket rim brands include XD Wheels, RAYS, SSR, and American Racing. Each brand offers its own unique design elements, construction quality, and customization options. Researching these brands and their offerings can help you find the perfect aftermarket rims for your car.

Factors to Consider When Choosing Aftermarket Rims

While the visual appeal of aftermarket rims is often a primary consideration, it’s important to take other factors into account when making your selection. Here are some key factors to consider:

  1. Weight Reduction and Performance: One significant advantage of aftermarket rims is their potential for weight reduction compared to OEM rims. Lighter rims can improve a vehicle’s acceleration, handling, and fuel efficiency. Studies have shown that heavy wheels can have a noticeable impact on performance, with slower acceleration and increased lap times compared to lighter options (Grassroots Motorsports). Therefore, selecting aftermarket rims that prioritize weight reduction can enhance your car’s overall performance.

  2. Fitment and Compatibility: It’s crucial to ensure that the aftermarket rims you choose are compatible with your vehicle. Consider factors such as bolt pattern, offset, and backspacing to ensure proper fitment and avoid issues with clearance, rubbing, or the need for modifications. Consulting with a knowledgeable expert or using fitment guides provided by manufacturers can help ensure a proper match.

  3. Durability and Quality: Look for aftermarket rims made from high-quality materials, such as aluminum alloys or forged metals, that offer durability and strength. Consider the reputation and track record of the brand to ensure that the rims are built to withstand the demands of everyday driving and potentially harsh road conditions.

  4. Customization Options: Aftermarket rims offer a wide range of customization options, allowing you to personalize your vehicle’s appearance. Consider different finishes, such as chrome, matte black, or brushed aluminum, to complement your car’s style. Additionally, some aftermarket rim manufacturers offer customizable options like center cap designs or engraved logos.

Weight Reduction and Performance

One of the key advantages of choosing aftermarket rims is the potential for weight reduction. Lighter rims can significantly improve a vehicle’s performance by reducing unsprung weight, which refers to the weight that is not supported by the suspension system. By reducing unsprung weight, aftermarket rims can enhance acceleration, braking, and handling.

Studies have compared the performance difference between heavy wheels and light wheels. Testing at the Florida International Rally and Motorsports Park revealed that heavy wheels slowed down a Mazda Miata by an average of 0.31 seconds and up to 0.46 seconds on the best lap on the kart track. Moreover, zero-to-60 times were notably slower with heavy wheels compared to lighter ones (Grassroots Motorsports). These findings highlight the significance of wheel weight on a vehicle’s overall performance.

It’s important to note that weight reduction should be balanced with other factors such as durability and material quality. Choosing lightweight aftermarket rims made from high-quality materials can provide the optimal combination of weight reduction and performance enhancement.

By considering the various aftermarket rim options, weighing the factors that matter most to you, and understanding the impact of weight reduction on performance, you can make an informed decision when selecting the best aftermarket rims for your car. Remember to consult with experts, utilize fitment guides, and prioritize reputable brands to ensure a successful and satisfying upgrade to your vehicle’s rims.

Importance of Backspacing Measurements

The backspacing measurements of the wheels used in the testing also played a crucial role in performance variation. The heavy Masitaly wheels had a 1/2 inch difference in backspacing compared to the lighter Volk TE37 wheels. This difference affected the car’s handling and stability, highlighting the significance of proper wheel fitment for optimal performance.

The weight difference between the heavy and light wheels used in the testing was substantial, with the heavy Masitaly wheels weighing 42 lbs., 4.6 oz. per corner, and the light Volk TE37 wheels weighing 30 lbs., 14.6 oz. per corner. This weight disparity further emphasized the impact of wheel weight on the performance of the Mazda Miata (Grassroots Motorsports).
