The Following quote is from the website you listed. Essentially, the 5606 and the 5658 are the same spring. What has changed is the height of the spring, which changes the spring rate. All things being equal and you SHORTEN the spring, you will INCREASE the spring rate. The Grand National came stock with a +/- 420 pound spring in the front. I have a 650 pound spring in the front of mine (which I bought from Hotchkis) and it's a good performer, but not good for the street. Too choppy for a comfortable ride.  |
I run 1000lb in my Lightning with QA1s. Its stiff but not bad, don't expect a Buick ride.
