Performance and Comfort
RS-R, the number one aftermarket spring manufacturer in Japan, is proud to bring their technology and know-how to the USA. Though all springs may look like they are the same, their performance is not. And because RS-R takes into account that every model of car has its own unique characteristics, the lowering springs ensure more than just the look you desire. Just because they fit, does not mean they were meant to perform properly for the car.
RS-R offers two types of lowering springs in the US, the Down Sus, and the Super Down Sus.
The Down Sus provides a lowered stance and improved handling to fulfill your needs to lower your car and improve its handling.
The Super Down Sus takes the car even lower for a more aggressive look and feel if you so desire.
In both spring choices, RS-R stays committed to providing comfort and performance that is matched to your vehicle's characteristics. Spring rates reflect factory suspension geometry, shock dampening, stock spring rate and ride height levels.
Bottom line: Whatever flavor of "low" life you choose, RS-R's technology, materials, and experience ensure the springs you choose will enhance your car's performance and looks without sacrificing comfort.
