As you drive, your car undergoes stress as the chassis twists and absorbs energy created by the force of inertia and gravity. Over the years, its been proven that a performance vehicle must reinforce the chassis and make a more rigid frame by connecting points 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 sway bars to do their job more effectively with more stability.
An H-Brace/H-Bracket connects the underside of your chassis and frame by connecting 4 crucial points underneath your chassis that undergo the most stress during cornering. Professional installation is HIGHLY recommended due to the familiarity of the connections between the chassis and subframes.
Please note that some ground clearance will be compromised; however this is often no greater than 2-inch and is often directly under the front wheels.
