When it comes to suspension upgrades, lowering springs are among the top choices for many Mazda RX-7 owners that are on a budget. These aftermarket parts not only enhance the aesthetics of your ride but also provide noticeable performance benefits. Let's dive into the details and see what makes lowering springs a must-have upgrade for your RX-7’s suspension.


Lower Center of Gravity -
By reducing your RX-7's ride height, lowering springs effectively drop the car's center of gravity. This change results in better handling, as it reduces body roll when cornering and improves overall stability. With a lower center of gravity, you'll experience a more responsive and agile driving experience, perfect for occasional track days or carving through twisty backroads.

Reduced Squat and Dive - Lowering springs can also help minimize the car's tendency to squat during acceleration and dive under hard braking. This improvement in weight transfer leads to more balanced handling, allowing you to accelerate and brake more effectively, giving you better control over your RX-7's driving dynamics in any given moment.

Enhanced Aerodynamics - A lower ride height can contribute to improved aerodynamics by reducing the amount of air that flows underneath the car. This reduction in drag can lead to increased fuel efficiency and potentially better high-speed stability.

Progressive Spring Rate - Many high-quality lowering springs feature a progressive spring rate, which means they offer a comfortable ride during normal driving conditions and become stiffer as they are compressed. This design allows for a smoother ride on the street while still providing the increased handling performance you're seeking.

Compatibility with Other Upgrades - Lowering springs can be combined with other performance suspension upgrades, such as aftermarket struts or sway bars, to create a comprehensive suspension package that maximizes your RX-7's handling potential.

While lowering springs provide a myriad of performance benefits, it's essential to choose a reputable brand and have them installed by an expert if you are unsure about installing them yourself. Keep in mind that adjusting the ride height may also require an alignment and adjustments to other suspension components to maintain proper geometry and preserve your tires.

In conclusion, lowering springs are an excellent investment for Mazda RX-7 owners looking to elevate their car's handling capabilities and overall driving experience. With a host of performance benefits, these aftermarket suspension components would undoubtedly help you unlock your RX-7's full potential.
