Spring Rates (rear)
When changing from a 10" spring to a 16" ish spring what changes would need to be made with the spring rates? (Running 175 lbs 225 lbs now)
-

Not really sure the total compression of each spring right now. (Car is tore apart for the winter) I read on a forum page someone had, there was a way to measure compression and figure what spring you would need! Their example was something like 13" 200 lbs spring would be a 16" 100-125 lbs spring. (Using a equation they came up with to get that). Stock car driver I should forget I saw that forum page and go with what the car knows and use what I have now just taller? (Trying to get more forward bit)

SCD is correct. A 200 pound spring is 200lbs/in,doesn't matter if it is five inches long or twenty inches long
Bill W. and Dr. Bob......who could have known.

I think your wanting more stored energy, by using a taller, weaker spring and maintaining your current ride height and spring seats. this is not hard to figure out if you know your specs for your 10 inch spring,

Gotcha! Thanks everyone for your help!!
-
Guess now the question would be... Is 16" what I should go with? Height isn't a issue, I have adjustable bucket with a 10" spring now.

Daaa , once again , thanks for clarifying my statement with you expert knowledge....just remember, 2 can play that game.....

More bite! Always struggled with pull off the corner! Guess I'm just going with the trend of what some of the front runners seem to be doing! Going threw the car this winter and wanted to try taller rear and softer front. (RF 1300 lf 1100 now.)
-
Is that why guys are running say RF 900 and LF1000? I saw a thread were someone posted that you had a thread about spring rates! I couldn't seem to find it! Instead of me asking dumb questions is that thread still around?

900/800

that's a conservative start that a lot of people have tried and liked. Spring rates can vary based on how high your motor is mounted, cell, even the cage etc. The last car I built myself everything was really high, I had to run stiffer springs in that car than my previous car.
you had a post a while back that you said you were about to retire from driving, I can see why with that 10 year old set up. theres stock cars down here on way softer springs than that and flying. it may not be a late model, but some of the modern day late model stuff works on stock cars to.

I won all 34 of my stock car wins in the last 9 years... My 50 plus pavement wins were all 94-2002.
Not sure what down here is but Ive been south in my IMCA car a few times.
Bama Bash in Alabama Champion
Ice Bowl at Talladega Short track in Alabama, Champion
2 out of 3 mains at Abilene Ice breaker
what year did you win the ice bowl ? ive been to all of them since 1996 and would like to verify that. if it was in the late 90s or early 2000s , you guys were ahead of the street stocks down here then, however for that race the rules were bent to accommodate folks from out of town . things are a lot different DOWN HERE now. why don't you come on back with the springs you mentioned earlier and try it again? and I don't care how much you blow your own horn advertising all your wins, I will bet you will get your azz handed to you........next

I won it in 2011 I think. There were no changes made for out of towners, when I won it, I ran a legal engine and a 2 barrel against their 4 barrels and added 300# to my car to make their rules.
There were cars with alum bodies against us stock body junkers.
I wont be coming down there again, I already won it and GAVE that Big Silver bowl trophy to a little kid in the stands.
I race modifieds now as you could tell by my signature under this if you had half a brain. What races have you won? You keep posting about what others are running yet nothing about yourself, lol..
I don't go to the bash, besides green valley is gone, now what year did you win the ice bowl ? and its best you don't come down here again, or that little kid will be greatly disappointed....

yea I remember you ,things are different now, how ever your accomplishments are a drop in the bucket as to what ive done myself and thru others over 30 plus years of racing. but im going to give you the win by default because I will not expose my personal info on an open internet forum. I have gained a lot of knowledge from this site, and yes ive learned things from you, im not ashamed to admit it, the problem I have with you is every time some one post something on here , you try to come back and belittle them with all your knowledge, don't ask me to elaborate, just look back thru your post here and in the power train section. any way , im done with this thread as it has gotten away from the OP question. you have a good day jeff joldersma.

If you want more drive off the corner increase your cross weight. I would suggest running the rates stock car suggested, except run the 900 in the rf and 800 in the lf. I will tell you that I switched from 11" rear springs to 13" rear springs between races a few yrs ago and went from a 8th place car to a winning car. The rates were the same between the 11 and 13's but had so much more traction with the 13" I couldn't believe it. Haven't ran 11" rears since lol.

Yes ladies and gentlemen! He has won again! He is the undisputed champion of the "Bench Racing 100"! LOL Lighten up dude.... people are on here trying to learn and share experience.... just sayin....
