Needing major help i have a harris chassis that is setup four bar on the left and swingarm on the right and the car has noooooo sidebite what so ever also i don't think the car is rolling on the right rear i do no that it is not pulling no weight off the left front both of the front corners just stays flat through the corner and down the straightways anyways here is my set up now and it is something i tried this weekend and of course it didn't work
springs
lf 650 rf 700
lr 175 rr 200
shocks
lf 74 rf 75
lr 95 rr 93
my top left bar is at 21 degrees and bottom at 8 degrees my right rear bar is 0 degrees with the swingarm being in the center hole one the frame My springs are mounted on the swingarm on the right and behind the axle on the left i am running a spring pullbar and a cushined j bar that is alllllll the way up on the frame and alllll the way down on the pinion i raised my ride heights higher then what harris calls for just to see if i could get the car to roll over and it was better last night then before but it is still nowhere near right so if anybody has anyyyy info on this setup that would be great thanks in advance Les
also my weights is around 56%rear 51 %cross and 52% left and my pullbar is set allllll the way to the left thanks again if you need anymore info just let me know i would really like to get it set up and run at least one race before the season is over



put someone in the car that can drive the car.and knows what to do with the car.

Krom you said for extra sidebite just lower the short bar down evenly on both sides right?

Yeah that should do it, you try it? It could make the car want to hike up bad.

Heavier RR spring, will help on corner entry.

Judging by one of the responses above, did you get into someone?

You say hike up bad do you mean on the left side?

Yeah lowering it will allow more body roll, and that will or should tighten it up when the track goes slick.

Yep on the left side, it will want to lift the LF more. Because of the added body roll.

Raising it on the frame side will induce more left side lift, and make more side bite, so its another option.

Both adjustments are handy, the 2nd one can be helpfull if the car is either tight or loose in the middle. But you gotta keep in mind if the car is up on the bars or off. If you raise the frame side when its off the bars in the middle of the coner it wil tighten you up side bite wise, if its on the bars it will loosen you up.

Most of the time with this swing / 4 link deal all i ever adjust at the track is front and rear stagger and the panhard bar. At the shop i will add or remove wedge and LR bite, or change springs.

How did the car run this past weekend?

It did ok but by the time the feature came around it was really really really slick and it just was not hooking up at all going in and it would come out right against the wall but when it is slick it is alot better then it was then the first time i talked to you but there was just a lot of racing going on this weekend and the track was just dry slick BAD it looked like a solid sheet of ice.
