We have picked up a nasty push in the center of the corner. Ran 2" of stagger on a big half mile. Semi-banked. I don't normally run that much but had a push in the heat and put more stagger in it to help but it didn't. Any suggestions???? This car has always been tight. We have never been able to loosen it up, no matter what I try. Willing to try about anything at this point.

I may have found my problem already. I lowered the jbar on the frame just before the feature and that moved the rear ens to the right in the car. Thus moving the left rear towards the center of the car which created more lfr bite. I know that are car does not like much bite. I have scaled it since my first post and foud that moving that j-bar and some tire diameters added 50# of bite to my original set up. I think this is where my push came from. Sound reasonable??

i always thought that movin the rearend to the right would loosin up the car.

Before we owned this car I would agree. I am not sure why but this DW8 does not like much left side bite. The more left side bite I put in it the tighter it becomes?? I run a plug in the lower left and I can't help but wonder if this compounds the push. It pushes just as he pickes up the throttle in the middle of the corner. I hear of other guys running huge amounts of bite 100+ is there a magic pounds of bite when it starts to loosen it back up?

OK Question then, I am running 4-bar left z-link right. Would I put static rearsteer or understeer in it. If you move the right forward it just allows it to move back more? and vise versa? Next question is how can you do this at the track with out changing the index on the bird cage? I have always used the bottom bars to square the rear end and the upper bars to index the bird cages. So if you move one the other must move also?? I don't know where you guys race but are pits are far from level. LOL. We have been super fast when the track matches our set up, but struggle when we have to change the set up to match the track. Just looking for idea's and trying to learn some more. thanks

viper,
i also have a dw8 and have in the past run the z-4 setup.
i discovered 2 things that the dw8 likes.

1. i burp the gas just before i turn in then stand on it through the corner ..it comes through good and if i enter as you do then i get a big mid corner push to the wall.

2. make sure your running at least 3 degrees of rf camber. the camber change curve on mine wasnt giving me enough and that helped a ton.

this is what worked on our dw8 and we also switched to a 4-4 rear setup , which i like a lot better too.

email me for more info if you want.

well if you have to stand on it to get it through the corner, i would say your a tad too tight.
first, everything starts in the shop, You should have different length swedge tubes made up, so you can change angles and not mess with your indexing or wheel base,
we run a Pierce and we can move all our links in every hole of the suspension and nothing changes. all the holes are radiused perfect. If not then you need different length swedge tubes.

Don't the bars help the most on entry and exit? How much will they effect the corner? Thats a good topic! What are the things that have the most effect on the center of the corner? (other than driver error)

can you not run the car in a lil deeper and solve the problem...watch your pull bar angle...it will cause your tires to lose grip...jmo...
