Everyone seems to want to know what lowering springs to go with. It has been my opinion that knowing the spring rate is a very important part of that decision.
Depending on your goals...will depend on what set of springs you will want to purchase.
I can't tell you who makes the best springs or the worse. Nor do I know what drop each spring will have because I have seen everyone have different drops with every manufacture. However, for the majority, the springs will drop the cars as advertised by the manufacture. These rates are for hardtop cars.
I know some of you on SVT Performance have different springs then what is listed here and I ask you to post the spring rate for those sets also.
This is just a collection from various sites and I had to call the manufacturer on a few of them because I couldn't find it on any sites.
