Review SWIFT SPRINGS Sport Lowering Q50 fits RWD 2014–2018

Swift Springs is a renowned manufacturer of high-performance suspension components, and their 4N909 Sport Lowering Springs for the 2014-2018 Infiniti Q50 RWD (rear-wheel drive) are no exception. These springs are designed to provide a sportier and more aggressive look, while also enhancing the handling characteristics of your vehicle.

The Swift Springs 4N909 Sport Lowering Springs are made of SAE 9254V steel, which is known for its superior strength and durability. This material ensures that the springs can support the weight of your Q50 RWD while providing a consistent and precise ride. The springs are also shot-peened and tempered to increase their fatigue life, ensuring they will last for thousands of miles.

The 4N909 Sport Lowering Springs offer a drop of approximately 1.2 inches at the front and 1.5 inches at the rear, which not only gives your Q50 RWD a more aggressive stance but also helps to reduce body roll during cornering. This reduction in body roll allows the vehicle to respond more quickly and accurately to driver inputs, resulting in a more engaging and enjoyable driving experience.

Swift Springs take great pride in their manufacturing process, which involves using state-of-the-art equipment to ensure that each spring is produced to the highest standards. The springs are also coated with a protective powder finish, which not only looks great but also helps to protect the springs from the elements and corrosion.

Installation of the Swift Springs 4N909 Sport Lowering Springs is a straightforward process, and they are designed to be a direct replacement for the original equipment springs. However, it is always recommended to have them installed by a qualified technician to ensure that they are installed correctly and that your vehicle's alignment is checked and adjusted as necessary.

In summary, the Swift Springs 4N909 Sport Lowering Springs for the 2014-2018 Infiniti Q50 RWD are a high-quality and effective way to enhance the performance and appearance of your vehicle. Made from superior SAE 9254V steel, they offer a sportier look, improved handling, and a more engaging driving experience. With their durable construction, protective powder coating, and easy installation, these springs are an excellent investment for any Q50 RWD owner looking to take their vehicle to the next level.

Swift Spring's 4N909 Sport Lowering Springs are a popular aftermarket option for those looking to enhance the handling and aesthetic appeal of their Infiniti Q50 RWD 2014-2018 models. Here are some pros and cons to consider before making a purchase.

Pros:

1. Improved handling: Swift Springs are known for their high-performance characteristics. These lowering springs reduce the vehicle's center of gravity, which results in improved handling, better road grip, and reduced body roll during cornering.

2. Aesthetic appeal: The lowered ride height provided by the Swift Springs not only enhances the vehicle's sporty look but also makes it more visually appealing to many car enthusiasts.

3. Durability: Swift Springs are made from high-quality materials, ensuring a long lifespan and reliable performance.

4. Adjustable: These springs offer the flexibility of being adjustable, allowing users to fine-tune the ride height according to their preferences.

Cons:

1. Ride quality: Lowering springs, in general, can negatively impact ride quality. Swift Springs are stiffer than OEM springs, which can lead to a harsher ride, particularly over rough roads.

2. Cost: Swift Springs are more expensive than OEM springs. This is a common downside of aftermarket parts.

3. Installation: Installing lowering springs can be a complex process and may require professional help. The process includes removing the old springs and installing the new ones, which can be time-consuming and labor-intensive.

4. Potential clearance issues: Depending on the extent of the lowering, there may be clearance issues with the vehicle's suspension or other components. This could result in rubbing noises or damage to the vehicle.

Conclusion:

Swift Spring's 4N909 Sport Lowering Springs offer several benefits, such as improved handling, enhanced aesthetics, durability, and adjustability. However, they also come with potential downsides, such as a harsher ride quality, higher cost, complex installation process, and potential clearance issues. Ultimately, whether or not to invest in these springs depends on the individual's priorities and preferences. If handling and appearance are top priorities and the potential downsides are acceptable, Swift Springs could be a worthwhile investment. Otherwise, it may be best to stick with OEM springs.
