I have a 80 monte carlo hobby stock that I race on a 3/8 mile 8degree banked tacky track. I just put racing springs in the car a few weeks ago and it helped some what...I have 900lb spring in lf 1200 in rf 200 in lr and 250 in rr. my car weighs 2870 with me in it and full of fuel..rear percentage is 48.5. I have tried a few things but the only place it runs good is on the high side...I just need to make it run good anywhere cause only a few choice nights is there anything on the high side to run on.. I would really like the help and suggestions....we also can't run ballast or weight jacks.

Try swapping your rear springs around...a little left rear may help you..You didnt say much in the line of tips to the trouble your having pushing,loose, spinning out or what ever but you usually run the heavy spring on the left rear since you cant add lead......hope this helps..and right back with more info......Towman

it is very loose..the only way i can kep the back end under the car is if i run way up top on the cushion....I tried the springs in the recommended position(weaker on the right rear. but then I had a push on the entrance to the corner.

swap the rears like he said to cure the push try some stagger in the front and a little in the rear also

I can't run stagger. I am running hobby class and all four tires must be the same size either 205/75/15 or 205/70/15. but I will try swapping springs again and adjust with air pressures. do you think putting a 1/2 inch spacer in the left front spring would help the loose condidtion...or make it push??

Pump a tire up to 80 or 100 psi and leave it sit in the sun for a couple days. Usually makes an inch difference or so.

Ditch the 250 spring altogether and put a 175 in the RR, leave the LR at 200. Sounds like you need the rear softer in general to get some weight transfer. Also might try a 1000 or 1100 on the LF to help with the weight transfer too.

Only try 1 thing at a time or you'll never know what made the difference.

Raz you must have some big marbles because I would be running away from a tire with that much pressure. BOOM!

The rear percentage is low,try putting some hidden weight in somewhere or simply shovel some dirt into the trunk,i've seen people protect the fuel cell with railroad track too.

All excellent advice! Personally I'd want to 1. Swap the springs like Raz_900 suggested.
2. Put the shim over the righh rear spring.
Like was suggested-one thing at a time!

Didn't say pump it up and watch it!!

We haveta run Hoosier HTOV RC4's and are only allowed 1 size. We'll buy 4 tires and put 2 up to 80 PSI and set them beside the garage for a couple days. We usually leave them sit on the car trailer just in case they do blow.
