Our race-proven coilovers are custom built and valved to suit your specific needs, whether it be for everyday use or pro racing. Since 2008, every CEIKA order is unique, with fine-tuned spring rates and custom shock valving to match. Our shocks are custom valved, dyno tested, and guaranteed to provide you with the closest ride quality and handling desired with this upgrade. At CEIKA, we are fully committed to giving each and every order the attention and expertise it deserves. Our team of technical experts will provide you with the best support and guidance to make sure you get the most out of your suspension kit. Our Custom CEIKA Coilovers are used in all types of street and pro race cars all around the world, providing excellent performance and outstanding longevity. They are built to order based on three different shock design types: Type 1M: A modern and versatile option with a single damping knob on each shock that adjusts compression and rebound together for a perfect match. It provides a wide adjustment range and a damping setting that is always optimal with quick "on the fly" adjustment. Type 2M: Comes with external nitrogen reservoirs and separate compression and rebound adjustments for a more precise control of the damping behaviour. These will require more time to fine-tune and cannot be adjusted on the fly unless you have pre-test settings and kept notes of the numbers of clicks for each compression and rebound. Type 3M: The pro-end user option, allowing for a further fine-tuning of the suspension with separate adjustments for rebound, fast compression, and slow compression. We strongly recommend the Type 1M for daily use or even pro racers who want fast and easy adjustability of the car for any circumstance. With the Type 2M and 3M, you run the risk of setting up the damping adjustment incorrectly, leading to a bad handling experience. The Type 1M will provide a perfectly safe and efficient handling throughout its single adjustment range. Our Custom CEIKA Coilovers will greatly improve and renew your car's feel, providing a firm yet versatile ride that feels soft when going over bumpy surfaces.
