Professional technology for the street enthusiast.

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 isabsolutely 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!

Think of the JRZ as "having your cake, and eating it too"- truly superior handling mixed with a compliant yet amazingly controlled ride.

About JRZ: A widely recognized leader in track suspension throughout the world. Since 1995, JRZ has been the first and best suspension for the serious privateer racer.
With the inception of the RS line, we can offer amazingly flexible suspension system, at a positively excellent value...

The RS Series offer the client consistent, durable, repeatable results through quality materials and motorsports level adjustability that nothing in this price range can touch. JRZ worked for many years to develop a 'dual use' system that is sensitive enough for those who have felt the suspension of a competitive race car with shocks that can cost over 10k dollars, but durable enough for a street car that can see every day use if the owner wishes.
JRZ's valving and wide range of adjustability allows for everything from complaint street rates, around the 400 lbs. range all the way up to rates typically found on dedicated track machines in the 800-1000 lbs. without issue. Others adjustable dampers used in lesser kits manage only about +/- 150lbs of range before there valving is outside of ideal.

RS1 (NEW) (1 adjuster, dual compression and rebound): allows the driver to adjust ride with a single adjustment knob for the ease of use and cost friendliness of a street car suspension. The RS1 system offers a very wide range of adjustment, so weather your matching your chassis to performance street rates and tires, or stiff race-springs and R-compounds: the RS1 works fabulously!
Unlike 'budget minded' lines from other companies; each RS1 series shock is a direct descendent of winning RS-Pro technology, with high rigidity not found in other street-derived mono-tube shocks.
These are a truly motorsport derived product, engineered from a high end solution to be more affordable- not developed to meet a price point. This may be the last word in easy-to-use adjustable suspension! (also available matched to Eibach or H&R sport springs for an affordable, comfortable and highly sporty street solution that is non-hight adjustable.)
RS1 Update: RS1 kits from VAC do not have the noise issues that were part of the first batch sold. Buy with 100% confidence.

RS (2 adjuster, independent compression and rebound) : an affordable two-way solution that's dominant in BMW club racing. 2-way and easily adjustable, with no external reservoirs. These systems meet the needs of the dedicated club driver, or high end street car street car that spends weekends at the track in a competitive setting. Popular for a reason and highly sensitive to adjustment. The RS's control of both compression and rebound adjustment, independently. One can adjust the JRZ’s rebound without affecting compression.
The advantage of gas pressure is that it stops oil from foaming and provides lifting force for the piston. No one else has figured out how to build a seal that allows gas pressure in a true twin tube. JRZ is the only one in the world that can do this. It’s something they’ve learned at showroom stock racing, and their package now gets this technology to the affordable road system or your track car.

RS-Pro (2 adjuster, independent compression and rebound w/ external reservoir): Allows the driver to adjust compression and rebound, with the added heat dissipation and reserve of an external reservoir. A favorite of exotic car enthusiasts and often found on Porsches, Lamborghinis and Ferraris that raced and driven hard by real enthusiasts, but can still keep excellent street composure.
The RS-Pro system offers a very wide range of adjustment, so weather your matching your chassis to performance street rates and tires, or stiff race-springs and R-compounds: the RS-Pro works fabulously!
High rigidity motorsport derived dampers deliver exceptional body control for any street scenario or lap after lap of punishment.

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.
