A motion control beam (MCB) that reinforces the front and rear ends of the body and increases torsional rigidity.The new generation MAZDA3 and CX-30 have been added to the lineup.Both cars had many grades and it was unexpectedly difficult to fit, but because they are on the same platform, we were able to set one product number.

[Motion control beam]
・ Compatible models: MAZDA3 (all BP series) / CX-30 (all DM series)
-Part number: MBP4900
・ Price excluding tax: ¥ 86,000

At the front mounting point, a bracket is mounted on the front end of the suspension member, and the MCB body is bridged to the left and right and bolted.Rear to the rear end of the frame end.It is necessary to remove the front undercover and the rear bumper bracket when installing, but it is not necessary to remove the bumper on the front and back.

A friction plate suppresses the slight vibration transmitted through the damper shaft inside the main body.Friction type damper(Refer to the conceptual diagram).From the point of view of body reinforcement, we want to make it as rigid as possible, but if it is made too strong, the slight vibration of the car body from the road surface will be easily transmitted, which will make the rider uncomfortable.Therefore, adjust the strength of the disc spring to make the optimum settings for each model.

It is effective not only for tuned vehicles such as suspensions, but also for those who are starting to customize their own vehicles.
