McLaren MP412C Progressive Rate Lowering Springs

Description

This set of Velocity AP lowering coil springs is designed specifically as a direct replacement spring upgrade for the McLaren MP4-12C, reducing ride height by approximately 22mm for a more aggressive stance and improved handling characteristics.

Velocity AP coil springs are manufactured exclusively from high-quality, high-stress X5K spring steel. Although considerably more expensive than conventional spring steel, this advanced material allows further improvement over the original McLaren coil spring design by reducing the amount of steel required per spring. As a result, these replacement coil springs are approximately 30% lighter, with a reduced solid height that increases usable suspension travel.

X5K spring steel is widely used at the highest levels of motorsport, offering proven durability, strength, and consistency under extreme loads — an ideal choice for a high-performance platform such as the MP4-12C.

In addition to superior materials, these McLaren MP4-12C coil springs feature a unique tapered wire progressive-rate design, setting them apart from most OEM and aftermarket alternatives. By using a tapered wire rather than a constant diameter, the spring delivers a genuinely progressive rate throughout its compression and travel. This allows the spring rate to increase during hard cornering, while remaining compliant over uneven road surfaces.

This design provides a substantial increase in spring rate and handling performance without compromising ride comfort. As the spring de-rates, the shock absorber operates more effectively, improving rebound control, vehicle stability, and overall ride quality.

Benefits:

• Reduced overall weight

• Improved ride quality

• Sharper handling response

• Enhanced visual appearance

• Improved shock absorber performance
