Push your suspension performance to the next level with our coilover springs 16k 8″, built for drivers and builders who demand precision, control, and durability. These springs are specifically engineered for high-load applications where a firmer spring rate is needed to manage aggressive setups, aerodynamic loads, or heavy modifications. Each set is sold in pairs (2) and offers full compatibility with Function and Form Type 1, Type 2, Type 3, and Type 4 coilovers.
With a 16k spring rate, 2.5-inch (64mm) inner diameter, and 8-inch free length, these coilover springs are designed for advanced-level tuning. The higher spring rate significantly reduces body roll, brake dive, and acceleration squat, giving you sharper cornering response and a more planted ride during spirited or track-focused driving. Whether you’re managing higher downforce, engine swaps, or added chassis weight, the 16k stiffness delivers reliable control where softer springs fall short.
Manufactured from high-tensile strength steel and cold-wound for consistent performance, these springs are optimized for long-term durability and resistance to fatigue. The powder-coated finish protects against corrosion and wear, keeping your suspension looking clean and performing reliably season after season. These springs maintain consistent ride height under load and are built to resist sagging over time—even in high-stress driving environments.
The 2.5″ inner diameter makes them highly versatile across many coilover platforms, giving you the freedom to swap and adjust spring rates easily as your build evolves. The 8″ height provides a well-balanced ratio of stiffness to travel, offering adequate shock stroke while allowing for personalized ride height tuning.
Whether you’re setting up for competitive time attack, autocross, or simply want to improve high-speed stability on your performance street car, the coilover springs 16k 8″ are the right choice. Backed by years of suspension tuning and real-world motorsports testing, these springs offer the ideal combination of rigidity and reliability to meet your demands.
