The RS Pro street dampers have been developed from many years of professional racing experience. The RS Pro damper allows for external adjustment of both the rebound and compression functions of the damper. The valving technology is the same as that of the race version, and an external reservior is used to house the precise compression adjustment mechanism.
Upper mounts, main and helper springs included. Learn More

For: Mitsubishi Lancer YR: 2001-2007 Cyl: 4 App: 2.0L Turbo Evo 7-9
The FX100 System uses the Power Plus I Pressure Plate with a custom heavy-duty Steel Back Organic friction disc. This clutch is engineered for heavy-duty street use. It is specifically designed for extended wear and additional clamping force for the enthusiast who has added an exhaust system, an intake system, up to 50hp NO2 upgrade, or other non-forced induction external bolt-ons. It features only slightly increased pedal pressure, longer life than stock, and normal clutch feel during engagement and disengagement for a very smooth operation. Learn More

Engine bearings one of most vital components within an engine are often overlooked when considering high performance upgrades. Performance engineered; multi-layer bearings generate less heat than normal bearings by reducing friction. Cosworth Race bearing sets feature a unique combination of design; metallurgy engineering to deliver performance in extreme condits. Cosworth Race bearings setsare available in sizes to accommodate most applications. Size 1 bearings a nominal standard size are used most applications. Size 2 bearings feature an additional .001 clearance should be used
when extra clearance is required.
Key Features
High strength overlay plate with reduced thickness better control less friction
Hardened steel backing on connecting bearings
Increased crush better retention
3/4 grooving on Main Bearings providing optimum supply
Tight consistent wall tolerances
Oversize chamfers where applicable
Flash plating eliminated improved heat transfer
Tested to over 1000 horsepower! Learn More

For: Mitsubishi Lancer YR: 1992-1995 Cyl: 4 App: 2.0L Turbo Evo 1-3
The FX200 System uses the Power Plus I Pressure Plate and a Steel Backed Kevlar disc. This clutch is designed for the street enthusiast or weekend racer. The FX200 offers similar torque rating and holding capacity as the FX100, however, its life expectancy is increased with the Kevlar disc. Our Kevlar friction material is non-abrasive and doesn't score the mating surfaces. It features only slightly increased pedal pressure, significantly longer life than stock, and normal clutch feel during engagement and disengagement for the smoothest operation of any stage we offer. Minimum 500 Required break in miles. Please see The Technical guide for more details Learn More

JRZ Suspension Engineering is proud to introduce the JRZ RS1. a revolutionary development in multipurpose high performance damping. Applying our race winning technology. JRZ designed the JRZ RS1 to give ultimate comfort for public roads and precise chassis control when driving on track.
 
The JRZ RS1 is a high gas pressure. single adjustable monotube damper. The canister has been designed inside of the damper. JRZ inner canister technology gives the advantages of monotube canister dampers without the mounting concerns and complexity. Easy to install. the JRZ RS1 is available as a complete kit with mounting hardware and springs for all applications we support.Built on the same roduction 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 aluminium 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. 
Features

• 22 mm rod strut. 16 mm rod damper
• 24 clicks of rebound
• Adjustable gas pressure. mono tube
• Piston designed for high performance
• Large adjustment range

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. This damping balance is critical to maintaining tire contact with the road in addition to controlling the main mass of the vehicle. To satisfy the diverse needs of each driver’s application. the JRZ RS1 has an extra large adjustment range. With a few clicks you can turn your smooth street car into a crisp. rock solid track car in seconds. JRZ has designed the JRZ RS1 to give the end user the best possible damper to drive daily. while maintaining the racetrack performance that wins championships. The JRZ RS1 is shipped as a bolt-on kit and always comes with the personal support JRZ is known for. Using the best materials. coatings and aerospace standard manufacturing processes as in our motorsport line; the JRZ RS1 is designed to perform flawlessly. Adjustment is easy to perform and comes with the knowledge base only JRZ provides to his customers.
