Strut Bar For Stable Cornering

When you move around in your car you like to feel safe and comfortable. At the same time you also want to be able to get from one place to another as quickly as possible without compromising the safety of your drive. Now all cars are built so that they are safe. But if you use a performance car you need to drive them safely as well.

It is said that driving slow is the safer way to drive. But that is not always true and sometimes you need to be able to accelerate quickly to make it safer and sometimes you need to turn corners at a little high speed. When you have to turn corners at a higher speed then even if your car is safe you may feel a little alarmed if the car rolls a bit while it is turning.

Your instinct to feel alarmed is right and if during tight cornering you feel a sense of danger you should consider making the car more stable during cornering. You can easily do that by installing strut bars. To understand strut bars you need to understand that the car is a series of compromises between a large number of extremes.

For example if you want a comfortable ride each wheel should have an independent suspension.. That way when one wheel encounters a small bump, that wheel will absorb the bump and it will not be transmitted to the whole car. On the other hand if the suspension is too independent the car will roll a lot during turns as the suspension has too much flexibility. The strut bar links the suspensions so that this flexibility is reduced when the car is turning around a corner.

If you have a performance car the stability of the drive is important both from the performance and safety points of view. It therefore makes sense to understand products such as a strut bar and install them if they are required for your performance car. That way you will be able enjoy a higher level of performance with a higher degree of safety.

Yamaha YFZ450R - No 1 ATV Racing

If you thought last season’s all-conquering YFZ450 was impossible to top, get ready for a shock: enter the new race-ready 2009 YFZ450R. Totally uncompromising engineering makes this the most competitive sports ATV ever, with instant race-winning potential straight out of the box.

Its new, massively rigid but lightweight chassis of cast aluminum and steel holds the free-breathing 5-valve DOHC liquid-cooled 449cc single cylinder engine low in the chassis. Though the suspension is wider and longer than the ’08 YFZ450, the YFZ450R is shorter than its predecessor. That gives it a more agile, nimble feel. Increased wheel travel and longer suspension arms give a wider stance without compromising YFZ450R’s overall balance. New tread-pattern tyres make turn-in even more incisive. There’s a lightweight 220mm ‘wave’ brake disc and a whole new multi-adjustable spring and damper package. New rider ergonomics maximise rider comfort.

The 32-bit fuel injected engine, gearbox, clutch and exhaust have been heavily modified to deliver the perfect combination of holeshot acceleration and smooth power right through the rev range. Lubrication is done through an in-crankcase dry sump system, preventing oil starvation under fast cornering, while keeping weight low and mass centralized.
