Left Rear Spring Falling Out

[stock car driver]

I was hoping someone could give me the rate for either a 16" or 20" spring, knowing what I have currently. Any help would be greatly appreciated.

SEE right there above??? I quoted from your first post....

This is what I answered even though you forgot to put the ? at the end...

Yes, you answered my exact question. I already knew that I could just put another 250lb 16" spring in the back, but if you had read on to the other post that I had posted (the one before you had posted) and it clearly states that I was asking for a "spring rate conversions from a 13" 250 to a 16" or 20" spring". Not for someone to tell me that I need to put the same spring only longer in it. I realize that you are the Champion of the Ice Bowl and Bama Bash and I am not any kind of champion in racing. You have been around racing long enough to know that you don't want an 11" jack bolt sticking 10" out of the jack plate, that's just stupid. I do apologize if I wasn't clear enough in the beginning. I am trying to be perfectly clear now, all I wanted was the spring rate for a 16" or 20" that compress and be the same length as my current 13" spring. That question has already been answered in some detail by another fellow racer. So again let me apologize for being a beginner racer and not knowing that others couldn't interpret what I was asking. Oh ya let me apologize for leaving the question mark off at the end of my sentence, I didn't know that grammar was such a hot topic on 4m.net.

First off I would like to thank BushRacing67, that is exactly the information that I was looking for. As far as you said about the the slick track/hard tire or heavy track/soft tire, we have to run a stock DOT tire (I try to run BF Goodrich Radial T/A's when I can afford them). The track normal starts out heavy in the heats then turns really dry slick for the features. Our track will normally run 6 classes a night with UMP Modifieds being the main show. So with your recommendation for a 16" or 20" spring, I kinda have a combination of the two. If I was better off money wise right now, I would just buy both and try them. But I am pretty financially restraint right now. I am preparing to separate from the Navy and wont start my new job for a little bit. For the time being (until I can afford both springs) which one would you recommend me to purchase.

Now for the rest of you (Jeff): I have tried to utilize the information that was given, but for the most part failed miserably. Mainly stock car driver, that info was useless. I thought that I was pretty clear as to what I was asking for, but I guess not. I realize that I am only coming up on my second year in a stock car, but I am not to stupid to know that if I put in a spring that has the same rate just taller I would have to raise the jack bolt. I am not trying to do that. You can try it on your car and let us know how it works for you. I dont see how that would help a thing. So if you have anything that is useful, I would greatly appreciate the information otherwise I will use what BushRacing67 has said.

To Keith Baker: I appreciate your opinion, but the shock travel is the main reason why I am thinking that I will have the issue or the spring falling out. The way that we have the shock set up it has a lot more rollover travel than the spring will allow. As far as jack bolt changes, I dont have any spacer or different offset wheels. Right now, I have enough wheels to go racing and not tear any up. Jack bolt changes if recorded are a pretty cheap of making adjustments. All you have to do is reset all of the jack bolts to the way that it was set up on the scales and you are pretty much back to where you started (within a small margin of error).

How much is your spring compressed now ?

Try this equation for spring rates, force/(spring height - compressed height)=spring rate

You forgot to apologize for being STUPID.

Ok, if this is what you really want then here it is: I apologize for being stupid and not "properly" wording my question. Let me tell you about me, if you care. I have been an Electronics Technician in the United States Navy for the last 9 years. What is that you might ask? Well I will dumb it down so you can understand, I am responsible for the maintenance, troubleshooting, and repair of complex digital and analog circuits in multi-million dollar Communication (both line of sight and satellite), RADAR, and various Navigation system. Sounds pretty stupid to me. But as far as me being stupid about this question, ok fine. I can fix my "stupid" question and behavior with the proper knowledge and experience. You however can't fix your ignorance, your just stuck with it.

How much is your spring compressed now ?

I am not real sure how much is it right now, I will be able to check this weekend when I go to work on the car. But there isnt a lot of weight on the rear of the car because we are still working on a lot of the stuff back there. I will probably have to wait until I get the car completed and ready to scale before I can provide more exact numbers.

I think based on your stupidity shown here in this one thread you probably change light bulbs. If even, lol.

I doubt you could self study and pass the 7 hands on exams in ATT...

That said go read the stupid stuff your posting. The spring doesnt know if it has 1 inch or 10 inches of jack bolt above it. You dont have a assembled scaled car so you have no idea where your spring top will be.

You clearly dont have the smarts to ask what you really need to know.

What you really need is the measurement from someone for the rear wt jack height from the top of the frame. Then you can cut and weld yours in the right place....

lol. Either way thanks for the laughs.

Springs

Hey guys don't mean to interupt but, if he goes with softer spring same height, it will extend further and possibly stay in bucket!
But if softer it will also affect weight transfer from rear to front, it will make it free on throttle.
On another hand if he goes longer springs that effects spring table on car!
If you change from 13 to 16 or 20 inch springs, during throttle application the cars weight transfer to rear will be slower which effects how fast the loud pedal is mashed!
On the chain or strap to keep car down, what happens when your going into a turn and the spring isn't seated, no weight on left rear "tight" and all the sudden the spring touches perches, "weight on left rear, now "loose" all in the same corner! The car dosent have a brain but if it did it would be confused! Also if not on spring and on solid bars "solid suspension" imagine what happens when tire is crossing bumps it'll only touch the top of them.
Hope this helps your situation

See now that is useful information.

[stock car driver]

See now that is useful information.

yep dude you really are STUPID.

A softer 13 inch spring will be shorter when in the car and expose even more of your jack bolt...

I sure hope someone else is actually building this and your just standing around watching thinking of these stupid things to ask about, lol..

post up some pics of this NEW chassis you built

Facts

What I posted was facts and options to think about during decisions!
Lets play nice on here, this is a sport we all love doing and learning is part of it!
Heres another option for ya to make Street Stock Driver happy too!
Go with a 15 inch spring and 50 lbs softer, adjust weight jack to ride height and jack up car and see if it still stays on perch, if not go 25 lbs lighter and try it.
This is the only way without chain to hold car down.
Plus it wont change the spring table much!

I bet there's more guys winning on normal spring setups than a smashed down soft 20 or 16in spring. there's more to these cars than just putting a smashed down spring in them and heading to the front. weight placement high and low, BAR ANGLES, front end settings(bump and arkman) are some key factors in a street stock.. jmo

I will agree with that whole heartedly. Although in my current situation, I feel that the 16" or 20" spring is my only option. I will not be cutting the spring bucket out and lowering it, just not going to happen. We take into account pretty much everything you listed above, but if the left rear spring falls out then everything was done in waste. We run in a Pure Stock division, our rules say that we have to run strictly stock suspension components. But we can alter the upper rear control arm for pinion angle. In the rear we are allowed to run heim joint shocks, but front has to be stock. Only the rear is allowed to have jack bolts. So we are limited as to what adjustments we are allowed to make on the suspension. We try to get our front end setup as close as we can, while staying within the rules.

check you facebook, I sent you a message on there. That is where the pictures of my car are.
