Notes:

Understand the concepts of oversteer and understeer before altering springs rates. (On a street driven car, it is usually desirable to have a slightly higher wheel rate in the front than on the rear. This reduces the possibility of "spinning out".)

The part number for the rubber insulator that sits between the top of the spring and the vehicles frame is D9AZ-5536-A. Some people say to replace this part with a new service assembly every time the spring is changed to prevent undesirable noises and other complaints. Some say only to change it if it "looks bad". Additionally if this part repeatedly falls of the spring during installation, tape or an adhesive will likely make the job "go a lot easier".

Multiply Newton-Meters by 5.71 to obtain foot/pounds
Divide Newtons by 4.45 to obtain pounds
