Maybe someone can clarify something for me. Our car through out the whole year has fought with a tight condition or push. I run a DW8 and dirtworks set up sheet doesn't really have a recomendation cross that I can see. What I am thinking or have proven out on our car is anything over 49% cross it does not want to turn in or at center. Tell me if my thinking is right on this. The more cross you have the less or harder it is for the weight ot transfer to the RF. So I dropped the stagger to 1/2" and also run 47% cross with 10#'s of bite(sometimes reverse bite). It makes the car turn much better with having to pitch it,just roll into the corner now.(I am guessing because the lack of cross)
Since are track is ALWAYS dry slick and dusty, the small amount of stagger combined with a plug and short bar no-one has anyone for us coming out of the corner. Is this realalistic? I have looked through post after post and I can see that opinions very.

That just goes to show you that the sweet spot for every chassis can very. Also, driving style too of course.

Raising cross raises left rear bite. The more left rear, the more push.

Lowering cross will keep the car from throttle pushing but might make it loose out.

Increasing RR stagger will loosen center by decreasing cross if the car isn't rescaled.

i have the same issue on our dw8 and spoke with mike clark at the nationals.
he told me to run a 4" on the rf and to decrease the rear to 56% and that should stop the inherant dw8 push. i have not tried it but we did notice that running like 57% rear weight does help the car turn better and free it up. our cross is best at about 47% too.
we run 550 / 650 springs and lr 4",rr 4" ,lf 3" and rf 3" right now , its good but still gets a push if we dont get it in early enough.
let me know how the offset / rear weight works for you.
