The RS street dampers have been developed from many years of professional racing experience. The RS damper allows for external adjustment of both the rebound and compression functions of the damper. In addition to the same precise and accurate rebound adjustment as in the single adjustable race damper, the RS are double adjustable. The compression adjustment technology is the same as that of the race version. The RS does not utilize a separate canister. The RS has both the rebound and compression adjustments on the damper itself.

AEM's Plug & Play Engine Management System (EMS) plugs directly into a vehicle's factory ECU harness and requires no additional wiring or hardware. Windows compatible software (2000; XP; NT; 98; 95; ME) makes the task of copying; viewing and manipulating data as simple as a click of the mouse. An integrated tuning wizard allows users to create a base map specifically for a car’s configuration; regardless of what type of injectors; sensors; coils or other changes have been made. The AEM EMS's infinitely adjustable software allows tuners to program virtually any combination of engine control; power adders and auxiliary devices; and accurately delivers proper amounts of fuel and correct ignition timing for any boost level or operating condition.

JRZ Suspension Engineering is proud to offer our newest quadruple adjustable racing damper. the JRZ 14 31.  Building upon the years of success of our original quadruple adjustable. the 14 31 takes our damping philosophy to the next level.  Every adjustment has an increased damping force range with finer adjustments engineered to enable the chassis tuner to make significant. predictable changes every time. Compression and rebound adjustments are separated into the high speed and low speed piston velocity ranges affecting the bleed and blow off points of the damping curve. All oil flow paths in the JRZ 14 31 have been redesigned to maximize efficiency and give crisp feel to the driver.  Rebound valving has been completely redesigned to eliminate influence over compression forces and smooth pressure development. At the heart of the new JRZ 12 31 package is our latest motorsport piston. designed to give increased control over base characteristics. reduce hysteresis. and operate smoother.  To ensure that the valving designed into the JRZ 12 31 are the determining forces. JRZ has included new low friction coatings. seals and bearings with this package. Custom applications are available.  An easy to use system. the JRZ 14 31 enables the chassis tuner to achieve the desired mass control and handling with precision. Digressive high speed blow off adjustment allows for highly tuneable mass control while maintaining smooth response and without losing traction. The low speed bleed adjustment is a powerful tool that enables the chassis tuner to maximize grip and optimize vehicle balance.

Features:

• Rebound adjustment independent from compression
• Extra large adjustment range
• 12 clicks low speed compression
• 21 clicks high speed compression
• 8 clicks low speed rebound
• 15 clicks high

The result is a damper that provides ultimate chassis and ride height control with maximum mechanical traction. The JRZ standard 22 mm piston rod works in concert with the high speed valving to maximize blow off valve response. achieving solid chassis control without using a high spring rate. JRZ 14 31 dampers are shipped with 360 degree swivel hoses and are available with zero-inclusion quick disconnects for mounting canisters within the chassis for ease of adjustment accessibility.  Even with a large range. each adjustment is designed to be a small. even step giving precision and confidence when making changes.  Our newest motorsport piston has been developed to deliver a smooth and responsive damping characteristic.  To customize track to track setups and tailor the chassis to the driver; the JRZ 14 31 has an adjustment range able to provide damping to spring configurations ranging from 1.5-6Hz on vehicles with moderate to large aerodynamics loads.  The JRZ 14 31 is here to take you to the next level. Dedicated racing cars with experienced drivers deserving of the professional technology JRZ delivers. With valving designed and innovated by JRZ Suspension Engineering. the JRZ 14 31 is shipped as a custom configuration always tailored to the customer’s needs. and always comes with our world renowned personal service.

Benefits

• Precise control of the chassis and unsprung masses
• Easy to change damping curves
• Large adjustment range. with fine tuning ability

Brian Crower high performance camshafts are ground on state-of-the-art CNC cam grinders to insure accuracy and tolerances to within .02mm. Every Brian Crower camshaft profile has been prototyped and dyno tested for proven horsepower results prior to placed into mass production. By grinding cores in high volume; Brian Crower; Inc. is able to pass the cost savings on to the end user. Quality at an affordable price.
Brian Crower uses small diameter grinding wheels during the finishing phase when applicable to generate a more aggressive ramp rate for a faster cylinder fill rate. More air + more fuel = more power. Although it takes longer to grind the cams; research and development has proven that the inverted radius created by the small grinding wheel on the opening side delivers more horsepower on radius and roller rocker applications than the conventional; large diameter grinding wheels.
All Brian Crower cams are checked on a high speed; sub-micron accuracy measuring gauge. The Adcole Camshaft Measuring System uses individual measuring heads for each cam journal and cam lobe; with .01 micron resolution; taking one datum point each 1/10th of a degree or 3;600 data points per revolution. Measuring camshafts for rise error and chattermark detection; this model can measure 200 parts per hour. Learn More
