Update: spring rates have been tested but since I'm on a business trip I can't get the results as soon as I'd like. Mike at RRT will email me the charts. Once that's done I'll post it all up. He did say that the rates are very consistent (linear) and the one spring measured around 180. That's the front spring for sure and would be a 43 ft lbs increase over factory SS and 20 over Eibach. More to come!
