Extremely high rear bite numbers?

[Hodrod7]

My rear bite is 350 lbs with 53%rear 53%left and 59% cross. (Car isn't bad but could be better with drive off, and is a little loose) is my rear bite #s to high that they are taking from the right side?

Very possible

I think I somewhat figure why I have so much rear bite. (was searching for things at the track and tried the 16" and forgot about) I went from a lr 250 lbs 13" to a 250 lbs 16". with a 225 lbs 13"on the right side. Am I correct to say the 16" spring compressed to 13' will would be adding that much bite. If I want to run that 16" I am thinking I should go way lighter with the LR? (playing with on the scales tonight to find out)

yes. You got all that bite from loading that 16" spring up enough to return your ride height. A softer spring would allow you to keep bite closer to the old value.

drop the cross, way to high

[Hodrod7]

Only way ive been able to get the cross and bite down is to swap the rear springs. I went back to 13" on each side and it done the same thing, so I swapped the left to the right and cross went down to 55% and bite at 200 lbs. (900 lbs spring across the front, 225 LR and 275 rr is what they are now with lower cross) I'm concerned the 275 on the right will make me loose?

do you have screw jacks or spring adjusters? Adjust them, check tire sizes, check frame heights. Im personally see no reason to run a 16 inch spring, but don't know your setup, track or drive style. you don't say what type of car. way to many variables to give you an answer

It's a Metric car. Left 900 6/4. Right 900 3/8, this is what was on it 250 16" 8/3 left 225 13" 225 4/4, 60% cross with 350lbs of bite!! I have no problem going to a 13" across the back. But with this shock package should I have a heavier spring on the LR? Ride height is about 2" of rack with RF 3/8 higher. And I can adjust with screw jacks. Thanks for your help.

Put a 16" 175 rate spring in the left rear. Will lighten cross numbers. Car will want to climb up on the cars per say with the longer preloaded lr spring. Leave everything the same as it is with the 13" spring, and just change spring only, should be pretty close to what you had with the shorter spring. see how you like the feel of it.

I talked a friend into letting me set up car with light spring and a bunch of preload , and he loves it. Won his first race shortly after we done it.

Well, I left it alone last night, except I I tried a 10" spring with spacers on the rr (yes I can't leave stuff alone) Car wasn't bad but had a bad push when off then on the throttle (after I lifted going in and got back on it) But was loose if I drove it in and stayed on the throttle! I know a lot of this is the driver but I need to get it to a neutral spot!

Alot of what you are feeling in that last post is setup/driver. I don't believe that shock combo would be forgiving

[a1driver]

the long preload lr spring is inherently pushy when getting on the gas. make sure you get the car rotated before getting back on the gas

yes nose must be pointed where you want it, before throttle applied

Can someone explain a Rule of thumb with front springs? Say I had 1000 lf 900 RF and switched them what would that do with the car? Or even went to a 800 lf 900 RF? What I am asking is what will it do when going heavier/weaker on each front.

[Fox_hunter42]

cant answer your question, but if your lf is stiffer than rf its backwards. 1000 on rf may not be stiff enough, depending on track
