The Tanabe Under Brace is designed to tie key areas together under your car to improve chassis stiffness, and increase handling and performance. The Tanabe Under Brace is especially good for cars that are highly modified, and have more horsepower and torque over stock that causes the chassis to flex during launch or cornering. Each Tanabe Under Brace is designed to be strong, and last long, and as a special Tanabe only double i-beam frame that is strong and lightweight.
The Tanabe Under Brace is basically a strut tower bar except it's for under the car, instead of on the top. Redline Motive has one of the largest inventories of the Tanabe Under Brace.
