I need help with a Street Stock set-up

I need help with my street stock setup. The car pushes really bad getting into the corner and then very loose off the corner. I have an 800# LF, 900 or 950 RF, 175# LR, 200# RR spring. I have about 3/4" of front stagger and about 1 1/2" of rear stagger. I have 7 5/8" LF, 8 3/8" RF, 9 3/8" LR, 10 1/2" RR ride height on 70/245r15 American racer tires. Any help would be good. This is my second year of racing. Thanks.

I'm pretty sure your shocked wrong or you may need a better front spring. Just from experience. Don't worry about stagger with these american racer tires. The air pressure will make the difference. try 12lbs LF- 14RF    10LR - 11RR
I used to run the same spring setup there and really start moving towards the front on short runs. I would put the 900 in the LF and 1200 in the RF, the rears are fine. Outside of that, i would definitely say its a shock issue.

Everybody has good answers to your problem, so ill add my 2 cents aswell, try adjusting your brakes. You might not have enough rear brake. even if its ok putting more rear brake in will loosen it up going in an set you up for the center off.
 
Thanks everyone. I'm run 7lbs LF, 15 RF, 11 LR, and 16 RR for air pressure. If I change shocks, what should I go with? I'm not using any brakes. I have 4.56 gears with a powerglide in high gear, so it slows down by its self. Any other help would be good. Thanks.

Maybe you try some brakes to just enter the corner with. if ya just let off an turn the wheel going in - no offence- you probly go in the corner looking like a fwd 4 banger. give it some rear brake, shut the rf off an stab the pedal just before turning after you let off. try that in a practice prior to spending 400 bucks or more on a set of shocks. what shocks are on the dump truck now?.

456 gears are to much 373 are great i ran 373 last year  at afton and had two wins two sec and a 3 place finish put 13 lf 17 rf 11lr 12 rr  900 lf 11 rf 225lr 175 rr spring this will help the push in and loose off 2 much gear off the corner will make you spin.hope this helps you we have a lot of wins to show for it.

Wow.. yeah, ditch the 456 gears in a hurry.... must be screaming half-way down the straightaway.  For a track the size of Afton I would say 373s would be best (assuming you are running a gm rear either 7.5 or 8.5 that is) .  In years past we have had success there running 373's and also with 342's in..... gotta have a good amount of motor for the 342's though, otherwise it won't want to give you any power coming out of the corners.... I think running 16lbs in the RF is probably too much, I'd say drop it to 14 or so and bring the LF up a bit to at least 10...... JMO.
 
I already check the valve springs and everthing is good there. I'm turning about 6400 to 6800 RPM with the 4.56 gears with the powerglide in high gear. I have a 7.5 GM rearend with drum brakes on the rear and disc on the front. I have a vaccum booster in it and the brakes are very very soft. Thinking about going with just manual brake system and see how that will work. I have pro shocks ss100 in both front, pro shock ss200 in the LR, and QA1 3085 in the RR. Thanks everyone for all the help.
 
Well I think you need to look into running in low and 373 gears, but that is dwon the road. The first step I would take, and I am about saving money. Buy one RF spring at 1200# and place your 900# on the LF, take the rear and put the 200# on the LR and 175# on the RR. Scales would be nice and if you can get some let me know and I can give you some numbers. Since you sound like you don't have a bias, I would definately shut off the RF and try setting with brake. If you can fix the entry, it will help the exit. Tires, I would put your smallest on the LF and use the other 3  to get 1/2 to 1 inch stagger in the rear. With this benifit you can swap the LR and RF for more even wear and also for slight changes in stagger to match track conditions. I know everyone has some ideas, but this is what I would do and it only would cost 1 spring for now, see where that gets you.
 
Just to let everyone know that this is a pure stock car with everything in stock location and in stock mounts. The only changes that we have done is springs, stock type shocks , and gears. Nothing else was changed.

your gear is killing you right there. I turn 6000 with 3.42's and 5800 with 3.73. That gear is got you hooked up for sure(plus it's hooked up coming in with all that gear) cause is slowing your wheel spin down, I'll bet you didn't grow air pressure in the rears, and built 5 lbs in the RF. I'm guessing that's why your tight in and loose off is an after effect of tight, pushing entry will force a loose off condition. That 3085 with the ss200 medium is not helping the off situation. Move the ss200 to the RR and get yourself a Afco 1035 for your LR. If you can afford it. Get the Afcos all the way around. There like 65 each and will out perform the Pros no problem.

That powerglide isn't going to last long in high gear, get it down in low and 3.73 or 3.42's.

You will not need the brake much with the 3.73's, just a touch in the middle in 3 to get you off the bottom at afton.

You could try and put a ton of stagger in the rear, these american racers are better with 10 to 12 lbs than 16 or 18 trying to gain stagger. You'll gain side bite but loose forward bite.
