67 Barracuda- Brakes and suspension on a 5000 budget- advice needed

No, but I-35 between Austin and San Antonio is a road racing track most of the time. I plan on using it every day and it will see some aggressive driving.
Unless you have money just to piss away that laundry list of parts you have there most amature racers dont have in their track car.
All a great street car needs is a good set of tires, shocks and sway bars and its game over. Of course good brakes are always a blessing.
