Lowering Springs & Coilovers: KW's Performance

For many car enthusiasts, the pursuit of the perfect driving experience often involves delving into the world of aftermarket suspension modifications. Among the most popular upgrades are lowering springs and coilover suspension kits, both designed to enhance a vehicle's aesthetic and dynamic capabilities. When considering these enhancements, the name KW Suspensions frequently surfaces. Renowned for their engineering prowess and dedication to performance, KW offers a comprehensive range of solutions for drivers looking to lower their vehicles and improve handling. This article will explore whether KW provides lowering springs and coilover suspension kits, delving into the specifics of their offerings and what makes them stand out in the competitive automotive aftermarket.

Understanding Lowering Springs and Coilovers

Before we dive into KW's specific products, it's essential to understand the fundamental differences and benefits of lowering springs and coilover suspension kits.

Lowering Springs

Lowering springs are a direct replacement for your car's factory springs. They are designed with a shorter free length and a stiffer spring rate. The primary goals of installing lowering springs are:

• Aesthetic Improvement: To reduce the wheel gap, giving the car a more aggressive and sporty stance.
• Handling Enhancement: The stiffer spring rate reduces body roll during cornering, leading to a more responsive feel. The lower centre of gravity also contributes to improved stability.
• Weight Reduction: While minor, performance springs are often lighter than OEM equivalents.

However, lowering springs typically do not offer adjustability in ride height or damping. They are a simpler, more cost-effective way to achieve a lower stance and improved handling.

Coilover Suspension Kits

Coilovers, short for coil springs over shock absorbers, are a more integrated and advanced suspension solution. A coilover unit typically comprises a shock absorber body with an adjustable spring perch and an integrated spring. The key advantages of coilover systems include:

• Adjustable Ride Height: Coilovers allow for precise adjustment of the vehicle's ride height, enabling enthusiasts to fine-tune the stance to their exact preferences. This is often achieved through threaded bodies and adjustable spring perches.
• Adjustable Damping: Many coilover kits offer adjustable damping settings (rebound and compression), allowing drivers to tailor the suspension's firmness and responsiveness to different driving conditions or personal preferences.
• Performance Handling: Coilovers are engineered to provide superior handling characteristics, often featuring stiffer spring rates and high-performance damping technology.
• Corner Balancing: The ability to adjust ride height at each corner allows for precise corner balancing, optimising weight distribution and tyre contact for maximum grip.

While more expensive than lowering springs, coilovers offer a significantly higher degree of customisation and performance potential.
