*note shows that this is a sideswipe by not having the restitution within the 0-1 values.

The Chevrolet Cavalier had isolators on both the front and the rear bumpers. Due to the previous damage on the front of the cavalier only the rear bumper was used for these tests.

The isolators on the Chevrolet were measured for stroke distance after each test. On tests 1-3 only the passenger side isolator was sprayed with Christmas tree flocking. For tests 4-13 both isolators were foamed as there was a great difficulty determining the actual stroking for each test. The Dodge Charger had a foam absorber system. The following table shows the data for each test.
