my dw 8 has been so tight all season that i can not get it to turn into the corners without using the gas or brake to turn the car.
its driving me crazy.its a 4-z rearend setup
heres the setup.
lf650,rf680 lr 225 , rr250 on the swingarm
shocks are 3050lf,3535rf and 3030 on the back.
ride heights are 5,5-1/2,6,6-1/8
left side is birdcage with spring in rear on slider. lower link is at about 15 degrees up and upper is at about 30 degrees up
on the right the bars are lower 10 degrees up and rear 10 degrees up to back of car

weights are with driver and as follows
58 rear,50.4 cross, 54.2 left with 120lb. of bite.
i am also running 1/2" of static rear steer
with 1" stagger in rear .
we run on a big 1/3 mile with 9 degree banking.
when i let off the gas coming into the corner the car pushes so bad i have to nail the gas and use rear steer to turn it through the corners. its gatting really scarey some nights. pleeeeease help

"i am also running 1/2" of static rear steer"
-What tire is being lead? It needs to be the LR.

-Put a stiffer extending LR shock on.

-Soften up compression on front shocks.

-If you've got weight hanging on the rear, move it to the leftside of the car.

-Increase the compression on the RR shock.

-Soften RR spring.

-Add Stagger.

-Move the rearend over to the right about

-Do you have brake floaters? Lower the RR rod and raise the LR rod.

-Raise the panhard.

Try adjusting your driving style a little. See if it helps to set the car earlier on entry. By the info you provided, it looks like you've done everything there is to do to fix this condition.

yeah, i am leading the left rear. last night i tried to enter the corner hotter and turn in later which i think contibuted to the push some.
i am going to try more stagger and also a higher panhard bar with less angle and see if that helps.
also noticed that my rf a arm is getting bottomed on the frame. i may try raising my ride heights an inch all around and see if that helps too.
have you done anything with your ride heights and what heights do you run your panhard bar on a tacky track? i run a 15" eye to eye shorty bar.

You might try going to a 750 on the LF and put the 650 on the RF. This should loosen entry mainly with a very slight loosening up on exit. GL

we tried the reverse split with a 600 rf and 650 lf earlier this season and it made me even tighter. its really frustrating ya know.?

reverse split will make the car tighter. because as the body rolls it will take dynamic cross out of the car and therefore make the rr pull harder than the lr on braking so the car will pull to the right and be tighter.

try a 700 or 750 in the RF

You said you had z link bars at 10 degrees up on the lower and 10 degres up ro back of car on the rear. Is it really up or do you have the back bar running downhill to the frame from the birdcage? Meaning if you viewed the bars from outside the RR are the bars about parrallel and run downhill to the back of the car?

put a 600 in the lf, and raise the panhard bar. that will free up entry, and the panhard will free up all over.
you may work with brake floaters, more angle in the lr and less in the rr.
on some bullrings i run the short bar all the way up on the pinoin and about 1 inch of rake. also i run over 200 pounds of spring split at times, this makes the car super super super loose. but fast set up when cars are running into the side of the car all the time.

paulicker,you can soften up on the L.F.& loosen the car on entry,Stiffen the L.R.or swap the rear across reset the wheel weights & see if it is ok.If not add C.W.until the car turns in like you want it to then if it is tight off add a little stagger to keep it turning as you come off the corner.Also you can move the R.F. in 1-2 " an that will get you in better. cd2
