Introducing the ECS Tuning 3437357 12.5mm Wheel Spacers Bolt Kit, specifically designed for BMW vehicles with a 5x120 wheel bolt pattern, including the E90 model. These wheel spacers provide an excellent solution for those looking to enhance their car's wheel fitment, offering improved aesthetics and handling.

The ECS Tuning 12.5mm Wheel Spacers are manufactured from high-strength, forged aluminum material. This not only ensures a robust and durable construction but also keeps the weight to a minimum, thus maintaining optimal vehicle performance. The spacers are precision-machined to ensure a perfect fitment on your BMW, with no need for modifications to the wheels or hubs.

This bolt kit includes all the necessary hardware required for installation. Each spacer comes with four M12x1.50 bolts, four locking nuts, and four spring washers. The high-strength bolts are designed to provide secure wheel retention, while the locking nuts ensure that the bolts remain torqued to the correct tension. The spring washers help maintain a consistent gap between the wheel and the spacer, ensuring proper wheel centering and contact with the brake rotors.

The 12.5mm wheel spacers offer increased offset, allowing you to run wider wheels and tires. The improved wheel fitment not only enhances the overall look of your BMW but also provides better tire-to-road contact, which leads to improved handling and stability. The spacers are compatible with both stock and aftermarket wheels and can be used in conjunction with other wheel modifications, such as lowered suspension or larger brake kits.

Installation of the ECS Tuning 12.5mm Wheel Spacers is a straightforward process. The hardware included in the kit is designed to be used with standard wheel lug nuts and bolts. The spacers can be installed using a standard socket and torque wrench, with no need for any specialized tools. Properly follow the manufacturer's installation instructions to ensure a safe and secure installation.

In conclusion, the ECS Tuning 3437357 12.5mm Wheel Spacers Bolt Kit is an excellent addition for BMW enthusiasts looking to enhance their vehicle's appearance and handling. With their robust construction, precision machining, and easy installation, these spacers offer a reliable and effective solution for those looking to improve their wheel fitment.

ECS Tuning's 12.5mm wheel spacers bolt kit (part number 3437357) for BMW 5x120 applications, such as the E90 model, is designed to increase the clearance between the wheels and other components of the vehicle. This kit includes the necessary hardware for a bolt-on installation. Here are some potential pros and cons of using this product.

Pros:

1. Improved clearance: Installing these wheel spacers can provide more room between the wheels and other components. This can be particularly beneficial for those who use wider wheels or tires, as it can prevent rubbing and potential damage to the vehicle.

2. Better handling: A slight increase in wheel offset can lead to improved handling characteristics, as the wheels may now be more evenly balanced and centered.

3. Customizable look: Installing wheel spacers can give your vehicle a unique and custom look, as they can make the wheels appear to be further apart from each other.

Cons:

1. Potential for increased unsprung weight: Installing larger wheels and tires, which may require the use of wheel spacers, can increase the unsprung weight of the vehicle, affecting its ride quality and handling.

2. Increased stress on wheel studs: Wheel spacers can put additional stress on the wheel studs, which can potentially lead to their failure over time. It's important to ensure that the wheel studs are rated for the increased load and that they are properly torqued.

3. Potential for uneven tire wear: If the wheel spacers are not installed evenly or if the wheels are not balanced properly, it can lead to uneven tire wear, which can negatively impact handling and ride quality.

Conclusion:

ECS Tuning's 12.5mm wheel spacers bolt kit (part number 3437357) for BMW 5x120 applications can offer several benefits, such as improved clearance, better handling, and a customizable look. However, it's important to consider the potential downsides, such as increased unsprung weight, stress on wheel studs, and potential for uneven tire wear. Before making a purchase, it's recommended to consult with a professional mechanic or tire specialist to ensure that the installation is done correctly and safely. If done properly, the benefits of installing wheel spacers can outweigh the potential drawbacks.

Recommendation:

If you're considering purchasing ECS Tuning's 12.5mm wheel spacers bolt kit (part number 3437357) for your BMW E90 or other compatible application, it's important to ensure that you have the necessary knowledge and resources to install them correctly.
