Frequently Asked Questions
Upgrade your suspension setup with our coilover springs 18k 8″, designed for performance enthusiasts who demand ultimate control and stability under extreme conditions. These high-rate coilover springs are engineered for track-focused builds, high-downforce setups, and heavily modified vehicles requiring uncompromising stiffness and responsiveness. Each set is sold in pairs (2) and is fully compatible with Function and Form Type 1, Type 2, Type 3, and Type 4 coilovers.
With a spring rate of 18k, 2.5-inch (64mm) inner diameter, and 8-inch free length, this set offers advanced suspension tuning for those who need reduced body roll, minimized squat under acceleration, and sharp response through tight corners. Whether you’re managing heavy aerodynamic loads, a powerful engine swap, or dialing in the perfect corner balance, these springs are built to deliver.
Each spring is manufactured from high-tensile strength steel using a cold-wound process to ensure structural integrity, consistent tension, and long-term durability. The springs are finished with a durable powder coating to resist rust, corrosion, and wear in any driving condition. Even during prolonged high-performance driving, these springs retain their shape and compression characteristics without sagging or fading.
The 8-inch length offers a strong balance of stiffness and compression stroke, maintaining your desired ride height while still allowing for proper shock travel. With a 2.5″ ID, they are compatible with a wide variety of coilover brands, not just Function and Form, making them a versatile solution for tuners and racers alike.
These coilover springs 18k 8″ are ideal for drivers pushing the limits on track or under competitive motorsports conditions. Their performance characteristics allow for more aggressive alignment setups and better weight transfer control, which translates to faster lap times and improved vehicle dynamics.
Whether you’re chasing podiums or fine-tuning your suspension for the street, our 18k 8″ coilover springs provide the uncompromising stiffness and precision needed to push your build further.
