RR Ride Height...and Bite

[joedoozer]

Where is your battery mounted? Left side %?

Right side on the dry sump tank mount. All my lead is on the RR upper frame just behind the axle. I have a monster fuel cell in it right now that I can't move any further to the right.

The nut is touching with the axle hanging on the chain. I can probably back it off a couple of turns and it will still be touching during hike. Then I can get the RR ride height back to what it should be and I will have about 100 pounds of bite.

Unsure of your left side percentage, but you will fix your problem by moving weight to the left.
Also do you scale with driver or ballast in seat?

your comment about not wanting to be on the chain limiter is wrong tho, you do want to run against it your lr is not reaching its full potential if you do not run against it, im not saying shorten the chain you need the car to lift to where the chain is now, and it should be on the axle not the birdcage just in case

I have 53.8% left side with me in the car.

When I scale the car I get in it and write all the numbers down. Then I get out and start putting weight in the car. I move it around until the numbers match to when I was in it.

After what others have said I realize I don't need the nut touching the spring when its hanging on the chain. I can back the nut off a few turns. That should lower the bite enough and I can put the RR ride height back to normal.

I started the thread to get opinions on my train of thought. I wanted to make sure I was understanding what was going on. Somehow it got sidetracked.

If I hold a rock in my hand and drop it, will it hit the ground. The size of the rock, color, shape, what hand.....none of that matters. It was a what happens if....type thread.

What happens is.... The world comes to an end and you get swallowed by a black hole. LOL
Was it pea gravel or lime stone....

Haha. The rock bounced....so that changes everything.

Hey if you talk to them often then you would know that Warrior wants you to be on the chain when the LR drops not one or two inches shy of it full extenstion. On the 2007 an up cars your LR drop needs to be no more than 15 1/4 inches between top rail and axle tube. I know this thread is not about LR drop but your showing other issues you may have with your car.

What year car is it?

Actually raising the lr upper CAN loosen your car............
If you have four mounts at the frame for the lr upper,and your in the second hole up, and the cars is able to hike up to a tight chain, raising that bar to hole 3 or 4 up will not add any more total dynamic wedge, ( it will develop a little faster) , but it will add more loose roll steer, which may loosen the car when hiked to the same max chain/same droop extension,compared to hole # 2.

Also, I scale w/o driver and shoot for ~53% left. With driver ends up ~57% when we checked it (if I remember correctly.)

living truth if you have 57% left you are way off.


once the car is on the bars the spring does nothing so it dont matter if the adjuster nut is close to the spring or not. the car shouldnt be on the spring but just for a short moment as it is climbing the bars and after the car is on the bars it is pretty ridgid so the direct pressure applied through a solid link will apply way more pressure than a spring ever could. so use what springs you want, set bite and ride heights an dont worry about adjuster nuts.

if the car is tight on the chain and you raise your bar and gain angle in the bar, that bar is going to have more thrust angle witch will apply more pressure to that tire. the bar angle is whats producing the forward bite in the car, the more angle the more direct the pressure is pushing down so the more pressure that tire see's. then after about 45* the bars dont gain enough pressure to over ride the added roll steer then you will start loosening up the car.

It appears the rock bounced and hit someone in the eye, then ricocheted into traffic causing a massive pileup on the interstate... Jeez Louise!!!

lol, indeed.

Joe think you're on the right track as far as your original question.

if the car is tight on the chain, then your not going to gain any more thrust to that tire by raising top bar, however you will increase rear steer which will loosen car,

Sorry, I agree with 4bangerhotrod on this one. The chain isn't holding the car up the bar is, so more angle IS producing more thrust. It's not like it hits the chain and somehow magically locks in place, the bar is still providing the force to keep it up and that force vector is dependent upon the angle that the bar is at. To a point...after about 45 degrees it looses its effectiveness. I've even seen birdcages cam over doing this and that makes a racecar very evil to drive.
Set your chain length so that the upper bar is at about 45 degrees in the slick and you should be alright. Changing chain length makes a very noticeable difference in handling.
When a bar change is made that increases thrust angle to tighten the car but also increases rear steer to loosen the car, you can usually bet that the net result will be tighter unless you are on really hard tires or way off somewhere else on your setup.
