I have a lot of people telling me different things and I really don't know what to do.
The car is tight getting in which I beleive is causing a push throught he middle of the turns. What can I do to loosen up on entry.

Springs Percentages Air pressure
Lf 1000 Cross 53% Lf 11lbs
Rf 1200 Rear 51.7% Rf 15lbs
Lr 175 Left 51.5% Lr 10lbs
Rr 200 Right 48.5% Rr 13lbs

Front stagger 1"
Rear stagger 1 3/4"

In order to get it to turn in I have to stay on the gas on entry until it turns. When I get back in the gas I pick up a push. The other thing that is bothering me is that when I get back in the gas I carry the left front through the corner which seems unusual for a metric car. Any thoughts would be appreciated.

it sounds like your rolling over on the right rear tire you need to keep the left front on the track to get rid of the pushdont know if this will help but we run900's in the front 200's in the rear55%left52to 53%cross56%rear pretty good for the most partstill looking for more we do run a metric also

If I use the brake it unhooks the back end and tries to slingshot it around the front. I guess I could dial in a little less back to keep that from happening. From what I have read looks like this could be fixed by adding more weight to the left side of the car.

i would increase the stagger a bit which in turn will decrease the cross weight. 1 3/4 might not be enough. go to 2 1/2 or even 3 and try it. you can always put it back.

If your running a locked or welded rearend
then I think stagger will get you in. and I would reverse the rear springs. I dont know of but a couple of street stocks that will carry a lf and one of those had a broken frame, but if you are carring the lf in the turn then you are getting on the gas much harder than needed. If you are having to stay on the gas until it turns, are you pwr sliding it into the turn? You may need to relax and let the car come in a little slower and at a different angle. you never said what the alignment settings were nor any info on the banking or track conditions, but assuming its like most of us, the car should generally begin to turn without much problem. This is only my opinion. bob

LF -1 1/2
RF +4 1/2

LF -1 1/2
RF +2 1/2

about 12 degree banking and very tacky.

What is swapping the rear springs going to do?

Is going to a 225 from a 200 enough of a jump?

Swapping the rear springs around will make a very noticable difference. Personally, I'd never run the heavier spring on the right. I use a 200 on the RR and a 225 on the LR. If it's pushing goin' in, I'll swap a 250 into the left rear. Just gotta watch on exit though. With the 250 in the LR, mine wants to loop around a little more in 2 and 4 but gets into 1 and 3 MUCH better. I just run either no stagger or 1/2" reverse to help coming out. I know it sounds crazy running reverse stagger, but if you'd ever run the asphal... errr.. dirt at my track you'd understand.

hopefully the camber you posted is a misnomer.( maybe pos lf 1.5/neg rf 3.5) I would also take a look at caster I can;t think of a reason to run negative lf
nor a 6 degree split. A big caster split really won't help on the rest of the track I agree with replacin the lr spring with a 225 and leave the 200rr alone. I would also
set the rf toe at 0 to the rear and toe the lf out 1/8th inch. these are a lot of changes and will take some getting used to but should get you into the turn quite differently than you were experiencing.

From what I can understand the car is tight through the whole corner, on entry and on the power. Here is what I would try in this order

1) Compare your corner entry location on the track to what the faster cars are doing. If you enter the corner too low and pushing up through the center of the corner, you may be creating your own problem. Get someone to video tape your race and review it.

2)Verify that you have free travel of the RF wheel no binding or bottoming out. Take the spring out and make sure the wheel moves up and down freely.

3) Decrease wedge - try 49%, might be too much, but this will definetly loosen the car up

4) Try around 3" of rear stagger if you can get it, not sure your tire rules

5) Try a softer RF spring (easy test is to swap the rf with the lf - reverse split)

Every car and driver is different, but what worked for me is reversing the front springs. I also started getting out of the gas a little earlier and then one quick punch to the floor to set the car and feather the gas around the turns.

Now if i could just quit blowing motors.....

in my experience a heavier rr spring will loosen you coming off and tighten you going in. most people use a stiffer lr than rr.

I like the sprint car mentality of gasing threw the corner just as he says. If it pushes immediately when you get back in the throttle and then works wonderfully through the rest of the corner then I would look at rear roll center and shocks. I would decrease rebound on left rear so that it rolls to right rear sooner. You might want to raise roll center a tad if the shocks don't work.

front stagger gets you in rear stagger gets you off but i would look at you rear spring placement normally would roun 25-50lbs heavy on right rear(i run same front springs 250lr 200rr) increase front stagger to help getting in then use rear stagger to fix exit.
you may find if you fix entry it may fix alot of your handling problems. i also run
1-3/4 rear stagger but almost 2-3/4 frtont stagger.hope this helps
