[QUOTE="ZD302GT, post: 15695441, member: 81883"] I am no drag expert by any means but I have always been under the impression that you want a harder spring in the rear. The reason being that if you have a softer spring in the rear and the car squats you are using weight transfer energy to compress a spring, that energy is not being transferred through and down to the tire for extra force to the ground. A harder rear spring would not compress as much and send that energy to the ground. I believe you do want a softer front setup so that the front will come up, giving you the transfer of energy. I don't know if that is correct or not but logically that makes sense to me. Also, since you have the SRA now you can think about roll centers (anti-squat). This video is not really drag related but it is enlightening to think about the engineering. He also mentions that having a high percentage of anti-squat or even over 100% can be beneficial for drag cars. [MEDIA=youtube]UhjQXJ6Yegs[/MEDIA] [/QUOTE]
