I'm wondering if anyone knows the dimensions of the stock springs in our cars. This summer I want to upgrade the springs for a much stiffer ride (I'm thinking kg/mm springs http://www.kgm.co.jp ) but I need to know the size. Reason I dont really want eibachs or anything is because whenever I'm looking at them all I see is the drop and not the spring rate and it makes me think they are more for the look. any info would be great.
