Having a spring rate which is too high, will result in a car´s suspension not being able to absorb all road regularities. This is because of the amount of force needed to compress the spring. The ride will be harsh and somewhat choppy, it will be hard putting power down on corner exits, with lots of wheel spin.

5.1 Introduction Logging unit costs are estimated by dividing machine rates by the production rates for the various logging activities. Logging components considered here are felling, bucking, skidding, loading, and transport. 5.2 Felling and Bucking The major

(iii) Load each vehicle so that the load on each course monitoring and candidate tire is 85 percent of the test load specified in 575.104(h). (iv) Adjust wheel alignment to the midpoint of the vehicle manufacturer 's specifications, unless adjustment to the midpoint is not recommended by the manufacturer ; in that case, adjust the alignment to the manufacturer 's recommended setting.
