If you look at the current technology available to the BMW enthusiast; its clear that there are many Koni and Bilstein based solutions for the damper and coilover customer. While these have their place, all of these are based on decades old technology that has its inherited limitations as mass produced products.

 
For those that love products that deliver outstanding performance, and quality- with the understanding that these cost a bit more; we are very happy to provide them with the JRZ RS1 damper kit. Available for a growing list of high-end late model BMW chassis, RS1 shocks and struts represent the latest technology developed from professional racing dampers to offer this technology to the enthusiast. RS1 however are the latest generation of tech, with only a small cost premium over the common contenders. Read on to find out why RS1s are such an exciting new product:

The most obvious improvement of what RS1 offer over the old standards is absolutely amazing handling with terrific ride quality. Not one or the other, but a both without compromise. That means even with lower ride heights, higher spring rates, and aggressive driving over uneven surfaces; the chassis is far more composed than any typical mass produced shock, even over rough pavement and on your favorite street road.

 
In their soft setting range, they offer ride that is typically as, or more comfortable, and faster than even OEM on the street. For the times when you wish to go to the track, you may quickly adjust the suspension stiffer for smooth- high grip surfaces, and expect sharp and athletic response suitable for a true track day car. NO other suspension offers this level of adjustment to such a high degree at the RS1!

As these are high end solution, there are details that you may wish to discuss with a professional. We welcome your call or email us for a no-pressure chat with one of our setup gurus.
