Racing History

Won 1966 Trans-Am 2.5 Championship
Won 1970 Trans-Am 2.5 Championship 

Strong Points

• The Alfa DOHC Motor is considered a classic that produced the most power per cc in the series.  The GTA used a 1570 cc motor and the GTV used a 1779 cc motor.
• Strong acceleration, especially in the GTV.

Weak Points

• Noted for developing extreme understeer.
• Trans-AM rules required a weight penalty.  This was added as ballast with a 99 lb skidplate under the fuel cell and a 50 lb plate under the engine.
• Live rear axel (though this does not seem to be much of a problem).

Common Setup

• 1570, 1779 and 2000 motors were used.
• 48/52 front to rear weight to help reduce understeer.
• Common to use aluminum hood and doors in the 2.5 Challenge.
• Dual Webers
• Front and rear ventilated brakes.
• Minilite 15 inch wheels.
• SCCA Recognition Form A1-6 from 1970 or earlier (PDF)
