That is what I am trying to accomplish, more or less, by playing with the bump stops. The stops are not solid, they are a very firm rubber type material, so they will give some when compressed. It should still have some travel, but have a stiff effective dampening rate. Basically the same thing as very stiff shocks.... thats the theory anyway

 

Excellent point!!!

 

My point about the bump stops it's that you have no control over how much or how little you will rebound off them. If you cant control the dampening you won't be able to control the rebound either.

The other Guy makes a very valid point about shocks. That's why alot of the off road guys go with the king shocks. There infinitely adjustable by changing the shim packs and valving internally. While you don't need kings to solve your issue any rebuild able/ adjustable shock should do the trick. You should be able to contact the manufacture to get different internal guts to make it do what you want it to do.

 

Hmm... skip to about 1:05 and watch the rear on the launch
It appears to drop a few inches and only rebound slightly once. This was with the front end straped down pretty tight. I realize the front coming up some is going to happen, but I am trying to keep the weight pretty even across all 4 tires are opposed to transferring all the weight to the back 2.

From what ive read, with a 4wd or awd truck you do not want much weight to transfer and you want it stiff as a board basically. Unfortunetly theres not a ton of 4wd hooking info. Most guys that overpower your standard 4wd end up just using 2wd and big slicks it seems.

 

I understand your theory and it is like you said, you want it as stiff as a board to keep things as settled as possible. After watching your video it is clear that you bottom out quickly almost immediately as you take off and it makes the truck completely unsettled. The weight transfer happens so fast that the front lifts up to the point that the front wheels struggle to hold traction. While I agree that it is worth it to try those bump stops since they were free, I will be surprised if they do anything. You need a lot stiffer valving in the rear end to settle things out especially because you are 4wd

 

Might wanna get ahold to stock48
if i remember right, he was running his low enought he is pretty much leaving on the bump stops?
or atleast the rear doesnt compress any?
I cant remember.

 

build some struts for the rear just for track use

 

It almost appears as if its bouncing of the stops, What kind of adjustable shocks are you using???

 

Richard, get some Cal-Tracs. Believe it or not, you're getting spring-wrap.

They will also help with anti-squat and body seperation.

 

I was thinking the along the axle wrap lines myself. Front is going up, rear is still attempting to go forwards, so there's the speed difference to let it happen.
Why not slap the gopro underneath it and watch exactly what's its doing???
