The Eibach Pro-Kit for the Seat Leon Cupra is a high-performance suspension spring system designed to lower the vehicle's centre of gravity and improve handling without sacrificing ride quality. It is widely considered a standard first step for enthusiasts looking to reduce the "wheel arch gap" while maintaining daily drivability.
•Performance and Design: The Pro-Kit is engineered to work specifically with standard OEM dampers, making it a cost-effective upgrade compared to full coilover systems.
•Lowering Amount: On most Cupra models (like the 5F), the drop is approximately 15mm at the front and 10mm at the rear. This is more subtle than the Eibach Sportline kit, which offers a deeper drop but may be too firm for some daily drivers.
•Progressive Spring Design: These springs use a progressive rate, meaning they remain soft during normal driving to absorb bumps but firm up under heavy loads to reduce body roll in corners.
•Handling Benefits: By lowering the centre of gravity, the kit reduces squat during acceleration, nosedive during hard braking, and body roll during cornering.
