Outlaw, The simple answer is more stagger,less cross....to fix the tight in the middle.......which may fix the exit....You may be "breaking" the car loose to get it to turn......

Problem is, the simple answer isn't allways right.......If you list some more info,I bet you will get some more help......

Good Luck,

I would first make sure your right front isn't bottoming out or binding. I had the exact same problem on my car and found the rf was bottoming out in the middle of the turn causing a bad push. I race on a tight 1/4 mile high banked track as well. I added 1" of ride height and it fixed the problem. If it isn't that I would decrease rf spring rate

Outlaw........Sometimes new guys come to the forum and will not list thier setups....afraid of giving up some great "secret"........I always find that a little amusing......If thier setup is so great,why are they asking questions.......LOL

Now,I am not refering to you.......so please don't take that the wrong way.......

There are alot of knowledgeble people here,willing to share thier experiences with you.........the more info you give,the better answers you will get......

Basic weight distribution, spring rates,etc......all play such a major role.......it is difficult to suggest a change if one doesn't know the baseline.....

Lets look at 340's post.....(a good post)
He is right.....if you are bottoming out,you will have the problem......so check it, good advice..........He then suggested that if that is not the problem, decrease RF spring........That WAS good advice also....based on the info he had at the time..........Since then you have posted WHAT the rate is..........He would not offer the same advice now.........

Now, I have used his post for example to demonstrate how more info makes a difference........I don't think he will mind, he is a good guy and is helpful to others on the forum.....Otherwise,I would have not done so.........

I would also point out that now that you have listed the spring rate, 340's advice about bottoming is even more probabable.......

Let's look at my initial post......less cross and more stagger......Good advice ???
Maybee....... Both will help a push.....
But both of these items are very much a driver preference deal.........You could compute the "ideal" stagger for your car........But it would just be a exercise in math........Some drivers will want more,some less, some reverse.........Difficult to account for.....

Some other possible causes.......RR too soft,too much front brake bias,not enough rear weight,....where are your rear tires in relation to the front? Many possibilities............

Check for bottoming and add some stagger.........

Good Luck,

thanks snowman, i appreciate the help, i actually talked to a few guys around here they all say i am too soft in the front, but everybody differs, some say as much as 1250 in the rf, some say 1000, in your opinion, what would the proper springs and shocks be? the car weighs around 3200 lbs with me in it, as far as the rear springs, i do not know the weight but it has chrysler leafs with 3 springs in each side. again, thanks for the help, you guys rule!

1100 RF, 900 LF usually work well on a 3200 lb. car.

Thanks for the note snowman.....i want everyone to realize, the more you put in, the more you get out......

Do not be afraid to post your stuff on here, no one is going to gain much off of your setup simply because everyone drives differently. But if your car is doing something and with the setup information, generally, everyone here can help you in some way to get it straightened out, or at least point you in the right direction. Most of the time, fine tuning is going to be difficult to do because of so many variables. I played pin the tail on the donkey for many years, and I hope everyone that has a blindfold on will take it off and post your stuff and learn from each other. Learn, Share, Make friends and Go Fast! Bascially the forum's motto!

Thanks again.

Hey, Outlaw. Ask some of the guys at the track to see if somebody has a set of scales. A lot of information can be obtained from scaling your car. I meet a group of guy this year that helped me scale my car, and what I learned from that made a bid difference in my car. As far as spring rates are concerned, if you are still running stock springs, check with your local NAPA store. They usely have a book that tells alot about the stock springs for the year of car that you have.

Thank You Jammin.....for all that you do.....the whole idea of such a forum where people can help each other......Admirable..........Thank You.

Outlaw, The Camaro's are illegal around here,so I do not have any personal experience tuning them. Perhaps some of the other guys may be of more help in that area.

For a metric,I use 1000,1200,250,200 springs. Shocks LF 75, RF 77, and 94 on both rears. However, that is not meant to be a recomendation for you........The home track is a big 3/8 inside, 1/2 outside......moderately banked........ which requires a stiffer spring combo than a smaller track........

If I were going to a smaller track, I would try softer springs......Perhaps the ones 6-Pack reccomended.........

In general, the softest springs you can run with out bottoming out work best......So, I hesitate to say go stiffer without knowing what is happening.......Do you know yet if you are bottoming or how much travel you have?

If you have a anti-roll bar laying around,you could install it....to experiment....to find out if going stiffer will help........Understand also, going stiffer on the RF will tend to create understeer.....unless stiffer was what was needed in the first place........That sort of thing is what makes it all so interesting......or frustrating....depending on your point of veiw....lol

Have you scaled the car ???? Vitally Important......... I like at least 53 left,54 rear......But you will get many different opinions on that........

You must be ,at least, "in the ballpark" on weight distribution and springs......if not....then you have no baseline to begin to tune from........

Good Luck,

Snowman
