Tuned for Perfection: CEIKA Custom Made Coilovers.
Bolt-on guaranteed for Your Lexus RX 300 RX 350 RX400h XU 30 Awd (03~09)
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. Proper fine-tuning of the coilovers, as well as installation, is important, so make sure you have this task carried out by a professional and follow our guidelines or advice.
On top of renewing your car's suspension and steering feel, this upgrade will provide:
Bolt-on Installation and satisfaction guaranteed
12 Months Warranty
Fully Rebuildable and Upgradable. Excellent longevity and reliability even under extreme use and conditions

Upgrade to the CEIKA Coilover Suspension System and experience the difference for yourself.

Order your CEIKA Coilover Suspension System today and experience the ultimate in performance, handling, and adjustability. You can also read our previous customer reviews below to see what they have to say about us! Just like them, you won't regret it!
We strongly advise to make sure that every component in your chassis suspensions, steering components and subframe mounts are in good working conditions as upgrading to stiffer suspensions (especially with pillow ball tops) will make suspension play and noises more noticeable and the stronger forces applied on them will make worn out mounts and bushes wear out quickly. Good condition OEM bushes or new poly bushes upgrade along with the suspensions upgrade will insure a "like brand new" ride quality.

Love them, feels great, goes low enough on 16inch wheel
Only complaint I’d have is for the front coilover, it doesn’t come with the brake line bracket
Other than that, it feels great !

Great quality coilovers.
Amazing ride quality and performance. Rides as close to stock while lowered as possible. Tremendous improvement through corners.
Mateo Popich (Seattle, US)
Amazingly handling coilovers
The coilovers are excellent in their dampening and performance, I opted for the 7KG front and rear springs but I'd recommend maybe a softer rear for daily driving on poor quality roads as the bumps can get to you sometimes, otherwise the flatness of the handling is excellent.
Zavier Vaillancourt (Sainte-Therese, CA)
Thank you guys for the coilovers, the ride is perfect! not to stiff and perfectly low, like I asked. I didn't have to adjust the coilover ounce. couldn't ask for more. Plus the sipping was free and I pay like only 70$ cad of customs fee to canada.
Max (Melbourne, AU)
Great communication after purchase and the coilovers arrived earlier than expected. High quality parts that look great and bolted straight up without any problems, easy adjustment for both height and damping.
