RF 950, Shock 1275-3, Corner weight 540
LR 250, Shock 94, corner weight is 800
RR 175, shock 93, corner weight is 635

TIre pressures are LF 10, Rf 13, Lr 9, RR 9
left weight%53.4 rear 57.1, cross 53.2

Can someone tell me how to make the car have more forward bite.
Thanks

Where are your rear springs located? Panhard bar height/length/angle? How much lead/trail in rear end?

Your rear percentage is way to low. Get it around 58-60%. Put left spring in front right spring on top or behind. Put about 50lbs of left rear and try that. If it has a throttle push , take some left rear out. Why kind of track do you run at, what size, track condition I might be able to help you more.

Mod3- I'm not sure what you mean, please explain. How do you adjust left rear out while keeping your cross relatively the same? I am assuming you are speaking about lower the weight split between the left and right rear tires. I experience a throttle push and have been fighting that problem, but when I take cross out to help cure it, the car lacks forward bite. What would you suggest???

wfoondirt, springs are straight up, the panhard bar is maxed as far as the angle i'll have to get back with you on length, 20lbs of weight over the right rear with the battery. Left rear is inch longer than the right. I do not know much about indexing as far what does what. What will happen if i go to a softer rt rear spring?

mod3 we run on a big 3/8 track in mississippi high banks, most of the time in is very dry slick in the main. I am trying to learn as we go so some of my questions might be kinda of basic. We did 1in reverse stagger this week and it help but not enough. Trying to do some minor adjustments at a time.

[B]Mod3- Chad, try running more rear stager if you can get it out of your tires. Might try running less angle on pull bar. If you are running a rear mounted panhard bar try putting more angle in it. This will tighten you up going in, but will loosen you up in the middle of the corner when you pick the throttle back up.

Dirt on your 3 link where are your springs mounted and how much angle do you have in the trailing arms? What kind of pull bar do you have or is it a fith coil? Do you have a j- bar or panhard bar and do your rear wheels line up with your front wheels?How much stagger front and rear? How much pinion angle? Is the car just loose on the dry? Dan 21

My opinion is you have way to much LR wieght for a 3-Link car. Thats whats making the car loose going in.It is piviting on the LR. Its like you put the Left side brakes on going into the turn because you are getting so much Left side grip going in.
Coming off you need closer to 60% rear to get more bite. But also try moving your pull bar up it will take away some instant traction but it will make more coming off.
Good Luck!

First off, check the rear steer in the car. IS the rear end square in the chassis? I measure from the motor plate because some front end geometry may be off causing the wheel base to yeild a wrong setting. Second, you need more rear percentage period. Thirdly, what are your ride heights? what frame are you running? What shocks? Glad to help if I can.
