I need some advice on what to change to keep my '80 Camaro from being so loose in the turns. I race on 1/4 mile clay tracks. Any advice would be appreciated.

What are your spring rates, etc...?
Have you had the car scaled?
How much stagger do you run?
Give us some more info.

I am still running the factory leaf springs under the rear of the car. I have a stock coil spring in the left front. I am running a 95 S10 right front spring. I am running 235 60 R15's on the front and left rear. On the right rear I am running a 255 60R15. I have never had the car scaled. I probably should also mention that the fuel cell is offset to the left side of car.

Is it loose going in to the turn, or coming out, or both?

Loose coming out of the turn. I really have to be careful with the gas peddle or I have my hands full.

I did lower the air pressure to 30 pounds on the left rear and also lowered the spring rate a very small amount on the right rear. The car was completely different. I thank everybody for their advice. Car much better now.

How much lower do you think I should run on the left rear? I have to run standard street tires on the car. One of the race tracks requires a minimum of 30 pounds in all the tires. That is why I did not go any lower than 30 psi on the left rear. I was afraid of the tire coming of the bead if the pressure was to low. But if I can make the car even better, I am willing to give it a try.

well sounds like u need a big word bite u need to get the floor jack and a socket put it in the center of the rear end and jack the car up and see which clears the ground first this a quick check if u dont have scales available u need the right rear 1.5 to 1.75 off the floor or u can use a 2x4 which is not a true 2 inches set the tire pressure as recommended and try less stagger 1 in may be the best also camaros was made with 4 different factory rear springs on dirt the 4 leafs are better the 5 leaf are not as soft try .5to 1 inches stagger in the front also and what type of shocks are u running and what are your ride heights sound like u may have too much stagger

I know you could definately lower those tire pressures! I run smaller tires (by rules) and run 20 RF, 18LF, 16 LR, 18RR I've gone down to 17/14/15/16 depending on track condition. You've got to be sliding all over the place at those pressures!

I have not had the car on the track since October, but am planning to do some testing this spring at some local tracks. I plan to try various tire pressures to see how the car respondes. Thanks for all the advice.

check with steve smith autosports also, they have some great books to help get your car set up also. those books can be found in any stock car racing book too.
I agree with the assessment of you other guys too, jack the car up and see which side clears first, that is how I used to do it before I went to modifieds and was forced to scale play with your preassures and RECORD the info in a spreadsheet so you can use it later. I CRS so I write everything down. practice will make for a better car. also try some different tire sizes, I use weathermaster tires for the wifes pure stock they work well for traction lot like hoosiers
only sideways.

Hey TW,
I agree with fasttrack about the bite. If your running radial tires the only thing air pressure will change is your spring rates. You need to use the ole socket and jack and see which side of the backend of the car comes off the ground first. I don't care how much weight you put on the left side if the wedge is not right the right side of the car will never come off the ground before the left side. I when through the same problem your having last year. I put the biggest tire I had on the right front and that helped to shift weight to the left rear so that I had more wedge in the car. Everytime I came out of the corner I could get back on the gas without the car getting lose on me. It worked wonders and I ended up winning seven races last year. Hope this helps. 34RACING

Thanks again for the additional information. I have two practice days (maybe more if I play my cards right) scheduled at some local tracks. I plan to do some different changes to see how the car responds to the changes. Should make for an interesting year. Thanks again.

Check your private mail, I sent an html chart describing handling problems and some of their solutions. Sorry that I could not copy it to this post. If anyone would like an e-mail attachment please send me a request to machinah@aol.com.

TWLeach Try putting a half inch lowering block under the right rear spring or add one half inch of arch to left rear spring. Either one will put more cross weight into chassis.You can also use a stronger spring on the left rear.Any or all of this will tighten you up getting off corner. cd2

I got the email, Machinah. Thanks. It will save me a lot of time during my test and tune sessions this spring. Thanks again to all for all the great advice.
