As you drive your car undergoes stress as your whole chassis will twist and absorb a lot of energy created by the force of inertia and gravity. Over the years, it s been proven that a performance vehicle must reinforce the chassis and make a more rigid frame by connecting points in your vehicle that are crucial to the behavior of your vehicle. By connecting points in your chassis and reinforcing the frame you are able to channel that energy that is being absorbed by the chassis flex back into your suspension components. This allows your suspension components such as your springs, shocks, and swaybars to do their job more effectively with more stability. Constructed of a Light-Weight Anodized Aluminum for durability and longevity, these bars will surely be an efficient and effective upgrade for your S2000.
