Now you can try building your own, This car features adjustable counter-weight slots for perfect balance, Formula 1 inspired design, and engineered weight distribution.

Just add official BSA wheels and a 3.5oz steel weight and you're ready to roll your way to victory. Note: this car design has an extended wheelbase and therefore does not adhere to all Boy Scouts of America rules. So it may not be legal to compete in all sanctioned race events. Have fun and good luck racing!
