However the fact is these cars are not really suitable for cost effective after market vendors. They are about as developed as they can be for the chassis and the weight. Until you are prepared to strip weight out of the car there is vitually nothing you can do that is going to make a performance difference other than changing the motor the way Norwood does with turbos. Swaybars, shocks, wires, coils, etc are going to be priced at the equivalent Ferrari prices and offer little or nothing in temrs of performance.
The TR was the first car bult by Ferrari where its design, parts and execution were primarily aimed at the US white shoe squad. As a result the car was never successfully raced and nor was its engine in that size and form.
But I have one anyway !!
