TPC Racing

TPC Racing has been running JRZ dampers for years. Winning a Grand Am Championship, the 24 Hours of Daytona, Speed World Challenge Races, Motorola Cup Races, and put us on the Podium at a number of IMSA GT3 Challenge Races has proven to us and the world what a great product they are.

JRZ is proud to introduce a new Monotube damper: The JRZ RS1:



From JRZ:

The JRZ RS1 is a high gas pressure, single adjustable mono tube damper. The canister has been designed inside of the damper.

JRZ inner canister technology gives the advantages of mono tube dampers without the mounting concerns and complexity.

...

Built on the same production line and sharing components with our pro racing applications, the JRZ RS1 is of true professional heritage.

Following JRZ's design philosophy, the JRZ RS1 has a large 22mm diameter piston rod in strut applications and a 16mm diameter piston rod in aluminum damper applications.

The large piston rod magnifies the high pressure gas charge which means great chassis control without using a high spring rate or increasing harshness.

Utilizing a mono tube design with a high flow piston ensures the smoothest possible ride in normal conditions while the bleed adjustment gives the ability to tune for racing situations.

Unlike many other single adjustable suspensions, damping balance is carefully maintained between compression and rebound. The damping balance is critical to maintaining tire contact with the road in addition to controlling the main mass of the vehicle.

With a few clicks you can turn your smooth street car into a crisp, rock solid track car in seconds!

We have a client who before bringing the car to us purchased lowering springs(not the Eibachs that we recommend). The spring choice lowered the car too much and caused a lot of front end modulation that comes with the piston being too low in the shock body.

The car is this clients daily ride so installing a set of full JRZ RS Pros or an equivalent shock would not have worked as the ride would have been too firm. I caught word of the new JRZ damper through the grapevine here at the shop and we decided it would be a perfect addition to the car along with our specific bars, drop links and toe links.

The following video is one I put together of a simple street drive around the shop here in Jessup. There is no drifting or even going above the speed limit, this is a video to show how compliant this remarkable car is on the street.


The price is substantially less than the RS and Pro lines of JRZ dampers.

These shocks, like many JRZ applications are built to order and come to us from the netherlands w/o springs. The rates we use are proprietary and selected after interviewing the client.
