[QUOTE="cartoon, post: 310270, member: 14829"] Any single second on the race track is very important for the driver, in order to perform laser sharp maneuver, they will try to make the chassis as stiff as possible, stronger chassis will transfer the road information (or we can say it is the vibration from the road) more clearly from tyre to the steering wheel, so driver will know how much limit can he go. If the chassis is not stiff enough, chassis will absorb part of the vibration, causing the handling feel soft, and driver will get confuse and can’t perform the sharp maneuver. So the “strut bar” is born and available on the market. Of course, this came out another problem, if the chassis really strong, what will happen when accident strike? When the car hit an object from the front, the impact force will quickly transfer to the whole chassis, but strong chassis will not absorb much of the impact, so the chassis will have minimum of deform at any where of the chassis, this will make repairing of the chassis more difficult or even can’t be repair. How about the driver? Because the chassis can’t absorb the impact, and driver will suffer serious injury. Not everyone like a well train racing driver. Most of the cars today have design a collision zone or using the aluminum body for absorbing the impact effectively, so driver will suffer less of injury. For aftermarket performance part maker, they create the strut bar made by aluminum or carbon fiber, so it can strengthen the chassis and allow to be deforming when absorb the impact. For our UR (Ultra Racing), using the aluminum or carbon fiber material is too expensive. So we using the mild steel as our source for the strut bar, but reducing the thickness of the hollow tube or oval tube to 1.2mm~1.6mm. This has archive the same goal as using aluminum or carbon fiber material. Same method is applied on the HONDA Type-R machine. [/QUOTE]
