The Pro Sport Digressive Series Coilovers from YSR USA are designed to provide motoring enthusiasts with exceptional handling characteristics while maintaining a balanced ride comfort.

Digressive valved coilover systems are designed to provide a stiffer damping force at low shaft speeds while allowing for more fluid movement at higher shaft speeds. This means they offer a firmer feel during normal driving conditions (such as cornering and braking) while still being able to absorb larger impacts from bumps and potholes without making the ride overly harsh.

How Digressive Valving Works

• At low-speed shaft movements (like turning, accelerating, or braking), the dampers provide higher resistance, which enhances handling and chassis control.
• At high-speed shaft movements (such as hitting a pothole or bump), the resistance tapers off, allowing for more compliant shock absorption to improve ride comfort.

Are They Ideal for Daily Driving?

It depends on your priorities and expectations:

 Pros for Daily Driving:

• Better control & handling – Provides a more planted and predictable ride, which can be great for spirited driving or high-speed stability.
• Reduces body roll – Helps keep the car flatter through corners.
• Absorbs larger impacts well – Unlike linear valving, digressive damping softens high-speed impacts, making rough roads more tolerable.
• Performance-oriented feel – If you prefer a sportier, more connected driving experience, this setup will enhance that.

 Cons for Daily Driving:

• Firmer ride at low speeds – Can feel stiffer than a stock suspension setup, especially on city streets.
• Potential NVH (Noise, Vibration, Harshness) – Some setups may introduce more road noise or vibrations into the cabin.
• Not as “plush” as OEM comfort suspensions – If you prioritize a soft, luxury-style ride, digressive coilovers may not be ideal.

Best Use Cases

• Great for enthusiasts who enjoy spirited driving, autocross, or occasional track use but still want a tolerable daily ride.
• Works well on performance-oriented cars or those with a focus on improved handling.
• If paired with proper spring rates and damping adjustability, they can be tuned to provide a good balance between comfort and performance.

Alternatives

• If comfort is a priority, progressive or linear valved coilovers may provide a smoother and more predictable ride.

Note: Please allow 3-4 weeks on average for shipping, as each coilover system is custom-built to order.
