I am ready to order my springs and want some peoples thaughts and experience with spring rates.<br/>I'm not real concerned about comfort as my car is only used for car club events + travel to and from events.<br/>Events include track days, hillclimbs, motokhanas etc.<br/>I was just going to order the std japanese spring rate which seems to be 5kg/mm front &amp; 8kg/mm rear.<br/>TRD circuit are heaps stiffer in the rear. Spring rates&nbsp;are 6kg/mm front &amp; 12kg/mm rear<br/>So I'm not 100% sure what spring&nbsp;rates to order.<br/>&nbsp;<br/>&nbsp;<br/>https://www.classic-ford.org/mr2/mr2play/FindPost/91812Thu, 04 Apr 2013 19:55:10 GMT
