SolidWorks FEA (Finite Element Analysis) module enables our engineers to do simulated stress analysis. This tool, in a mechanical design engineer’s hands, can allow the parts to be made lighter and often stronger. Through the stress diagram the designer can see exactly where to remove material without making the part weaker.

Weight is certainly a factor in making a car accelerate and corner faster. The formula for acceleration is A=Force/Mass (weight). As you decrease mass with the same amount of force, acceleration goes up. That applies to both forward acceleration and side (cornering or lateral) acceleration. As an object moves in a radius, it accelerates towards the center of that radius. Lessen the weight and a car can corner faster.

Since we started using SolidWorks FEA in 2009, we have redesigned all of our major components on our 600cc chassis. If your chassis is older than 2010, you will want to consider upgrading your components to the newer style and lighter weight HBS components. For example, cars built in 2011 are 25 pounds lighter than those built in 2007, and those built today are even lighter.

Here is a list of some things to make your Hyper ride a little lighter.
