Chevrolet Montana - Handling Preview for a Racecar

The suspension for a road car focuses in a good compromise between Ride & Handling. When this car is a light pickup, there is also an important compromise between driver and full load condition.

For a race car, the suspension system must have a different compromise, were Ride is not considered, but it must be able to keep the tire in contact with the ground, transforming engine power into acceleration, brake power into deceleration and steering inputs in correct corner apex.

This paper describes the suspension modification in a production Chevrolet Montana and the methodology used to specify springs, anti roll bars and dampers, which has competed successfully in the 32^a Mil Milhas de Interlagos.
