Left side 4-bar clamped in front
Right z-link spring on top
90 lbs left rear
4-bar top bar 2nd hole up, bottom bar 4 deg up
Z-link rear bar 4deg down, front bar 1 hole up past level

with a 4 bar and the spring in front, I would bring it down a lot.
also what are you running for springs, You could lower your rf spring rate

I thought of that but I don't want to loose my forward bite. Can't I get this thing to rotate in the center without lossing my forward bite? This is the only thing from keeping me of winning. the car is so good everywhere else on the track. I forgot to mention I'm running a Jbar little rake in it, it's just about level and level with the pinion.

See if you get through the corner faster with out pushing and shuting the car car down to turn it you wont need all that forward bite,
Like they say If you cant get it in, you wont get it off!!

Donslink1 that makes sense! I 'll try it. What about adding more rear stear also? Thanks for the help.

Rear steer will help, I think less bite will help more.
Good luck!!

Is this right when you pick up the throttle?

I am assuming,
You could also lower your rf spring rate
I know of some guys running down in the 500# rang, That will free the car on the power.

I think for this weekend I'm going to take my Lr bite down to 50lbs run it in the heat and for the feature maybe add some more rear steer. After checking everything over tonight I noticed the my jacking bolt on the left rear scewed in a turn and my J-bar slid down a half an inch. The track was a little rough but I never had that stuff move on me before! So that made me even tighter than usual.
Andykmod, yes it is tight on the throttle.
Thanks Donslink1 for your PM input I really appreciate it.

You have to drive the car in on entry to see if the car is tight running that much left rear you are probaly tossing the car in and when you pick up the throttle the car is tight do like the guys say drop lr and drive the car in on entry.Also level out your lr lower bar you will be surprised with the drive off you have when your good on entry

Thanks for all the feedback guy's this is why I love this site. Some things I'm not getting. I was told to raise both lower bar's that it would help the rearsteer? You guy's say to level the lf lower bar out? Next is and I feel dumb for asking this question but what do you mean drive the car in on entry? Do you mean not tossing the rear out so much? Because right now that's what I have to do!

One other thing will I lose to much forward bite by lowering the LR bite? I just scaled the car and I was at 90 lbs LR and I took it to 54Lbs LR. If I take more out and the car drives in and through good and lose coming off what can I do to get more forward drive without putting in more LR bite?
Thanks again everyone for the input!

Thats what i mean drive the car on entry when you lower your lower bar in the slick that will take steer out and tighten car off this adding drive off Right now with my pierce car i am down to 10pds lr and it is good on entry with good side bite in the slick i went to 40pds rr and it got better but i had to drive the car in on entry.10pds early in lr slick 40rr with no driver.I could not believe it also the lower bar on the lr was below level. I wish some one could explain it to the only thing i can figure was the car was great on entry

all Bob is doing is taking the rearsteer out by lowering the lr lower.
So 44nymod thats what you can do when it gets slick, Lower your lr lower and or raise your rr upper on the z link.
but I would lower your bite we run 10# bite also with our Pierce.
you wont believe how much bite you can take out and still come off the corner like a rocket as long as you can go in and through the corner good!!!!
good luck

BOTTOM BARS ARE FOR STEER, BY RAISING THE RIGHT LOWER BAR WHEN THE CHASSIS ROLLS OVER IT MAKES THE BAR FLATTEN OUT WHICH MOVES THE RIGHT REAR TIRE BACKWARDS, PUTTING STEER IN THE CAR, OR LOSSING THE CAR. RASISING THE LOWER LEFT BAR PUT MORE ANGLE IN IT AND WHEN THE BIRDCAGE INDEX AND THE TIRES HOOK IT ALLOWS MORE STEER IN THE LEFT REAR. TOP BARS ARE DRIVE BARS AND BY RAISING THE BAR ON THE LEFT SIDE WHEN THE CAR IS "ON THE BARS" IT PINS THE LEFT REAR DOWN BECAUSE SO MUCH ANGLE IS IN THE BAR.

So, when you move the LR lower bar--which side (frame or rear end) and which direction do you move it? I'm having trouble getting angle in my z-link bar and I need another way to introduce rear-steer.

Any ideas?

Thanks,

Move the LR lower bar, up one hole on the frame side. Most adjustments concerning bars is movement on the frame side.

Raising that LR lower will get you some rear steer. Raising the upper bar on the left side can give you some more FWD bite.

Left side (driver side).

44nymod-

I talked with WPP for about an hour the other night from asking questions on here. He knows what he is talking about. I finally got my car to drive "well" in the wet/tacky/crumbs...which is over 1/2 the night at my local track.

I like my clamped up set up so much more than LR behind.

I'D LEAVE THE BASIC SET UP THE SAME BUT I WOULD TRAIL THE LEFT REAR BY 3/8 OF AN INCH TO START, THEN GO MORE IF NEEDED.WE DID THIS TO MY CAR AND IT WORKS GREAT AT 100 LBS OF BITE.

Are these adjustments for a car with spring in front of housing on the left rear locked up and RR spring on top of housing? Would these adjustments be the same if the LR spring was behind like most late models? Plus what panhard bar are must of you running with this combo and at what angle?
Would'nt putting the top LR bar at more angle also induce more roll steer because the rearend is indexing more and moving the rearend ahead? Or does one need to lenghthen the top bar so the birdcage does not move as far or over index?
Just some thoughts but I am probably way off. Thanks for the input.

Well we had a great night Sat. I took the LR bite down to 50lbs and left my bar angles the same. This freed the car up a ton and never lost any forward bite. The only problem I had was the rear steer that the car had for me it was too much. This is what costed me another win. With the track getting real dry slick, the rear steer to me felt like it slowed my corner exit. What I'd like to do is take rear steer out but I don't want to get tight in the center again.
Bar's are
LR Top 2nd hole up
LR lower 3rd hole up
RR rear z bar 3rd hole down
RR forward z bar 2nd hole up
Again any thoughts are greatly appreciated.
Oh my finishes Sat were:
1st in the stockcar
2nd in the Mod
Not a bad night at all!
