Std GC rates are 440 front and 350 rear on the 12+ Civic kits. Std rates on the 06-11 Civic Si kit is 425/250 (front is different because they have to use a shorter 5" front spring, and that's the only one they have available...and it works). Front spring on the 12+ Civic kit is a 6" spring and better. I am very opinionated when it comes to what works and what is best on these cars.... if you want any feedback about what you may need, shoot me a PM and I'll try to help give you good feedback. I get calls, pms and emails all the time about this.
Thank you. That is more of the information I am looking for. There are 3 different spring rates that you can get but I am starting to lean towards a koni/eibach setup.
