Bump steer is a change in toe when a wheel traverses irregularities on the road surface. In order to minimize bump steer--a condition that can be caused by using shorter springs to lower a vehicle--some manufacturers offer offset steering rack bushings. These offset steering-rack bushings can rotate inside the housing and compound the problem of bump steer. Therefore, HR recommends center-drill bushings only for all applications.

HR’s steering rack bushings offer the driver precise steering input, steering response and feedback. OEM stock rubber or urethane bushings are uncommunicative and far too soft for competitive driving. By eliminating the deflection caused by rubber or urethane bushings and modifying the location of the steering rack slightly, we achieve greater Ackerman steering and allow greater communication between the road and driver.

The RSTB provides the rear mounting platform for the roll cage via X-bracing (as shown in our X-System roll cage image). X-bracing from the top of the main hoop of a roll cage to our 'Force' or X-System RSTB creates a key plane of geometric triangulation: a marraige of the center to the rear portion of the chassis. Non-HR rollcages, if properly designed and modified, can be tied into our 'Force System', as well.

Our products begin with using better materials. By using certified materials, such as high quality steel, aluminum and titanium, we can custom tailor each component in the Häns Racecraft ‘Force System' to achieve maximum performance. Mechanical engineers with years of experience design our race systems. Our design team use state-of-the-art CAD/CAM software to create our products.

A system is defined as a series of independent parts functioning as a whole. We strive to achieve a state of synergy with our system where the whole is greater than the sum of the parts. That is, a state whereby our products tie into one another and achieve a much higher level of performance than they would be capable of individually. Our subframe connectors are designed to be tied into a roll cage that, in turn, is tied into our shock tower brace.

Attention to detail is a hallmark of Häns Racecraft. All of our finished products are abrasively blasted. This process cleans all oils, grease and debris from the manufacturing process and creates a porous surface so that the finish can properly adhere to the base material. After this stage, we finish with our premier Harsh EnvironmentTM polymer coating, whose protection is only surpassed by its beauty. The result is a showroom-class finish that combines form with function.

We have developed the one of the most uncompromising designs to date in the new Diamond™ series floormats. Our prestigious logo is balanced and proportional, visible from various angles including the exterior of the vehicle in most cases. Dense woven carpet fills the top surface to reflect elegance and refinement. Our innovative clean edge aids in a lasting appearance. Finally, we include positive location by rubber backing/grommet, so that the carpet remains where it was intended to be.

The most difficult forces to counter in a chassis are the loads that result in torsional deflection. It is important to minimize deflection under load. Modern unibody vehicles handle poorly under the stress that daily and competition driving can impart. This is largely the result of twisting (torsion) forces on the vehicle’s chassis that comes from cornering and engine torque. The chassis misalignment from these forces cause unpredictable handling and power loss.

Hard cornering, abrupt directional changes and rough roads translate into flexing of the rear shock towers. Flexing of the rear shock towers leads to a decrease in predictable handling. If you have made the decision to convert your stock suspension with a rear coil-over kit, our product is key for maximizing the benefits from such a system. Coilovers replace the larger, heavier stock spring with a smaller, lighter spring relocated around the shocks.

The driver’s primary feedback from the road is through the steering wheel. A vehicle with greater steering responsiveness has the competitive advantage. Negotiating turns with greater precision and speed promotes driver confidence and control not otherwise available. This element of control can often mean the difference between first and second place in a competition or avoiding a hazard on the road. Synergy is achieved with the investment into one of our premier steering rack bushings.

Our design allows a small but important relocation of the steering rack to affect the turning angles such that Ackerman steering is increased noticeably. No modification to the steering rack is required.

A lot! Almost all variants of TCP, several forms of multicast, wired networking, several ad hoc routing protocols and propagation models (but not cellular phones), data diffusion, satellite, and other stuff. See the documentation (described above) for details, or download ns and look.

Worn bushing are identified by looseness, cracks ,and off set bolts. Elongated or out of round bushings is another sign of worn bushings.

No, the rubber bellows are mainly designed to keep dirt out of the steering rack and only keep in a small amount of thick grease which lubricates the inner tie rod ends. Any signs of fluid in or leaking from the bellows means a seal inside the rack is leaking. Rislone Power Steering Stabilizer with Stop Leak is the perfect product to use for this type of leak.

In most cases, it's always a good idea to have a little extra room. Our Compression Type Clamping Bars (for example) are made with an ?" shorter front bar. This way the ends are finished, not just chopped off. Two inches is just a ball park figure.. you can go as much as 4 or 5 inches if you like.. As long as you center your guilt or wall hanging, everything should look fine. We at Robinson's Woodcrafts have made it a top priority to respect and protect the security of our customers.

Bushings are used in many locations on the vehicle suspension system. Most bushings are made with natural rubber. However, in some cases, urethane compounds may be used. Bushings made of natural rubber offer high tensile (tear) strength and excellent stability at low temperatures. Natural rubber is an elastomeric material. Elastomeric refers to the natural elastic nature of rubber to allow movement of the bushing in a twisting plane. Movement is controlled by the design of the rubber element.

Urethane bushing are a harder material the stock rubber. Generally a tighter more responsive ride is noticed after Urethane is installed.
