New Product!!Ohlins DFV Adjustable Suspension System

The ideal DFV system applies to both the compression and extension cycles

Ohlins originates from Sweden, starting off as a shock manufacturer for 2 wheel applications. Carrozzeria Japan supports Ohlins in Japan for the research and marketing of their products.

Ohlins's newest suspension is the DFV model which features the dual flow valve system (hence the DFV) that controls the attenuation of the moment at the beginning of the shock stroke.

"On the compression side of the shock, there is a sub-valve named the PCV in parallel to the main valve. In our new product, we incorporated this PCV valve in the extension side as well, for a dual flow valve design" claims Mr. Funabashi of Carrozzeria.

If the PCV was simply incorporated on both the compression and extension cycle sides of the shock absorber, then this simple theory would have been possible 6 years ago when the PCV was first used. But theoretically, with two sub-valves installed in a system, the stroke becomes reduced, hindering the overall efficiency of the shock. This is why it took so long to engineer a super compact design of a unit that has the sub-valve on both sides of the shock.

According to Mr. Funabashi, "the shock was ultra smooth against the pavement once the sub-valve was installed." They claim that the success of the new design was proven when the vehicle was tested on a bump.

The sub-valve also releases the oil pressure before the piston in the main valve so the shock is easier to begin its movements.

With the sub-valve on the compression cycle side, the instant wheel goes over the bump the sub-valve starts to work to absorb the impact resulting in a comfortable ride. However, once the vehicle starts to come off the bump to a flat surface and the sub-valve is not present, it relies on the main valve only. The result of this is that the impact of the wheel rolling off the bump increases. In other words, bad ride quality. This is why it is important to have the sub-valves on both sides of the cycles. Less impact means a comfortable ride.

Shown is the DFV piston. The unit has a sub-valve installed on both the compression and extension cycles. The compact design still enables full measurement of the stroke of the shock.

With the use of 3 channels on both the compression and extension cycle sides, the control of the attenuation of the moment at the beginning of the shock stroke is possible. Before the main valve starts to move, the sub-valve releases oil pressure for an overall comfortable ride.

To get the best feel of the DFV, a custom suspension for the CT9A was constructed. The front is the inverted type with steel casing and aluminum brackets. The rear is equipped with an aluminum casing that compliments the super light components that make up the rear suspension. The springs were set at 10 kg/mm front, and 8 kg/mm rear with a 20 way adjustable shock. This adjusts the compression and extension cycle of the shock at the same time.

KC Racing is currently supplying this latest Ohlins product and we have a set to suit Mitsubishi Lancer Evolution IX in stock. Others also available for Z33, BNR34, GDB, AP1, SE3P and NCEC, please contact us for further information.

New Product!!Work -- Work Emotion XT-7 light alloys for VW MK5 Golf GTI and R32

The new 2006 model Seven Spokes WORK Emotion XT7
Great Cars need great wheels. In other words, wheels of first class quality and enormous strength, which can effortlessly carry a considerable weight and the associated maximum axle loads. Ideally, light, since weight optimized wheels tend to tramp less (lower un-sprung weight) and provide optimum contact to the road. The result of permanent grip: higher cornering forces, which in turn mean improved driving safety and in the last analysis, greater ride comfort.

Advantages of the new WORK Emotion
The multi spoke styling of the XT7 wheel designs represents the ideal solution for weight optimized wheels. The forces acting on them are guided perfectly to the center of the wheel spider by the even spacing of the seven. Thus it is possible to avoid excessive wall thickness and achieve a low wheel weight. Another important advantage, particularly in the case of high capacity vehicles, is the excellent brake ventilation and therefore improved braking behaviour.

Test proven advantages of the new WORK Emotion
The weight from the Suspension apparatus which includes the Tire and Wheel combination is called “Un-sprung Weight”, and reducing the weight of this section is crucial to the performance of the vehicle. If 1kg of weight is saved from the suspension system, the value of a 15kg weight loss from the vehicle’s overall weight can be saved. This means if an aluminum wheel which is 1kg lighter than a stock steel wheel is installed, 60kg of total of body weight can be saved.

Specifications & Price
Our supplier has requested Work Wheel, Japan custom produced the latest model Work Emotion XT-7 in 18” x 7.5”, ET50, 5 x 112 light alloys to suit VW MK5 Golf GTI and R32. This wheel not only gives another choice to car owners but it allows enough space to big brake kit installation. Each wheel weights 10kg, which is an excellent weight saving comparing to the heavy stock wheel.

We have asked our supplier to give KC Racing a special price to buyers at HK@2,190 each. It comes in Bronze and Gun Metal colour. Supplier only has limited stock in hand, so please contact us now for stock reservation.
