Scroll down about half way and they do a little right up on it. Not a step by step but you can see how they braced it. If you are trying to do this yourself i would follw Wild Cherry's step by step and look at the pics of the team cars to see how they braced it. I will post a couple pics of mine later today. Lowe's car is braced with aluminum but most of the team use an L brace or carbon fiber.
