[DeTomaso] Engine Bay Brace question

[Thomas Borcich]

My fabricator is building a new adjustable engine bay brace ... I've seen the X or dual type brace and wonder if how important the bottom brace is and what improvements I will notice? I will be doing some track days and solo 1, my rear tires will be 285's, and I hope to be getting 450-480 horsepower from the 351, brakes for now will remain stock. As always thanks for the input.
