The Ford FR3Z-5560-X rear coil springs are a premium upgrade for the 2015-2020 Ford Mustang Shelby GT350R. Designed specifically for high-performance applications, these springs are engineered to provide superior handling and ride quality.
Constructed from SAE 9254 cold-wound, chrome silicon steel, these heavy-duty coil springs offer increased stiffness and durability compared to the OEM springs. This enhanced spring rate not only improves the overall performance of the vehicle by reducing body roll and squat during acceleration but also gives the Mustang a lower and more aggressive stance.
These Ford Mustang Shelby GT350R rear coil springs are manufactured with a precise roll-form technology, ensuring consistent diameter and height throughout the entire length of the spring. Furthermore, they undergo a shot-peening process that adds an additional layer of strength and stress relief to the spring surface.
The shot-peened surface texture also helps prevent the formation of fatigue cracks that can occur over extended use. This results in longer spring life and improved overall performance for the Mustang. The premium quality finish applied to these coil springs is resistant to chipping, making them not only durable but also aesthetically pleasing.
Each rear coil spring includes a steel-reinforced eyeling and a tapered eye shape. This design feature improves the clamping force between the spring and associated components, resulting in better load transfer during aggressive driving conditions. Additionally, the tapered eye shape reduces the stress concentrations around the spring's attachment points, reducing the likelihood of cracking and minimizing the potential for system failure.
These Ford FR3Z-5560-X rear coil springs come in sets of two, making them a direct replacement for the OEM springs. Installation is straightforward, and no modifications are necessary for a bolt-on fitment. Designed to meet or exceed OEM specifications, these high-performance coil springs are an ideal addition for discerning Mustang enthusiasts seeking improved handling, enhanced looks, and uncompromised ride quality for their 2015-2020 Ford Mustang Shelby GT350R.
Buying Ford FR350Z-5560-X 2015-2020 Mustang Shelby GT350R rear coil springs can be a valuable investment for those seeking to enhance their vehicle's performance and handling. Below are some potential pros and cons to help you make an informed decision.
Pros:1. Improved handling: The Shelby GT350R rear coil springs are specifically designed to provide better handling characteristics. They are stiffer than the stock springs, reducing body roll and improving stability during cornering.
2. Enhanced ride quality: Although the springs are stiffer, they offer a more controlled ride than the factory springs, especially during aggressive driving. This results in reduced wheel hop and improved road feedback.
3. Lowered ride height: Installing the GT350R rear coil springs can decrease the vehicle's ride height, giving it a sleeker appearance and potentially improving aerodynamics.
4. Suitability for performance modifications: Upgrading to GT350R springs prepares your Mustang for further performance modifications, allowing you to take full advantage of other upgrades, such as performance exhausts, intakes, and suspensions.
Cons:1. Cost: Replacing the rear coil springs with the GT350R units can be a relatively expensive modification. These springs are not the most affordable option, and the overall installation cost, including the springs and labor, can add up.
2. Importance of proper installation: Properly installing aftermarket springs is crucial for their performance and safety benefits. An improper installation could lead to negative consequences, such as accidental damage to the vehicle or decreased performance instead of improved handling.
3. Limited ride comfort: The stiffer springs may decrease overall ride comfort, making the ride less pleasant during daily driving. Newer drivers or those who frequently travel on rough roads should be aware of this potential downside.
4. Additional wear: Upgrading to aftermarket springs may result in additional wear on other related components such as sway bars, shocks, and struts. Regular maintenance and timely replacement of these parts may be necessary to maintain peak performance.
Conclusion:When considering the purchase of Ford FR350Z-5560-X 2015-2020 Mustang Shelby GT350R rear coil springs, weigh the benefits of enhanced handling, improved ride quality, lowered ride height, and compatibility with future modifications against the potential drawbacks of cost, importance of proper installation, and limited ride comfort. If you value performance and handling improvements over comfort and cost, and are planning on further modifications, these springs could be a worthwhile investment for your Mustang. However, if you prioritize comfort and affordability, it may be best to consider other options or live with the factory springs. Ultimately, it is crucial to build a suspension setup tailored to your specific driving needs and preferences.
