It will have to be done by the center of the contact patch. Offsets will change it. I get the strong feeling that we are being tested here and not being asked a question. The purpose of this forum is to learn, not to try to show how much better you are than someone else simply because you know more about something. Please keep this in mind. Learning to make our sport better is what this is about.

Jammin, Are you telling us someone would ask a question just for the sake of arguement then show us the proof they are right after we have all made fools of ourselves????????

Jammin,this is not a test or is it an actual emergency.No wait heard that on the radio,uh,what was the topic again,oh ya,motion ratios.I read in a book that wheel rates are the actual number a person should use when comparing chassis set-ups not the spring rates wheel rates are figured by taking the motion ratio times the spring rate.I'm trying to put a larson chassis set-up on my 95 larkins.I think I know how to figure motion ratio's but wanted to see if some else out there figured it the same way. ttp://216.117.149.191/ubb/smilies/cwm36.gif[/IMG]

If you know how to do it, then what is the question? Am I doing this right?

Jammin,yes the reason I asked the question the way I did was to see if anyone came up with the same answer as I did.I ain't no brainiac,and I don't know if everything I read in a book is true so I try to confirm these things by bouncing it off other people and see what they think.the larson cars are running a 1300 and 1000 lb. front springs with a solid pullbar I would like to get the same wheel rates In my car for tonights races,I came up with a 1200 and 900 for the 76 chevelle stub,but I decided to go with an 1100 and an 800.I usually run no more than an 850 rf so before I take a pushin sled to the track wanted to try and confirm my numbers with someone.
