Since it took so damn long to load the first pic, i didnt look at the others. It looked great to me. I would not change a thing.

Is he complaining?

Not complaining, but there are some things that need to be adjusted, i think i have since figured it out but want others' opinions and then i'll explain what I know is wrong and hopefully show what to look for when setting-up your truck. Like "if you watch the way the front does this and reacts like that then you can determine what needs work". I figure instead of just talking about tuning, we can do real life "workshop" stuff.

The only thing it needs is numbers on the sides.....

what adjustments can you make? Is your shock a double bypass, tripple...?? Just guessing here, but it looks like your front gets kicked up a little when hitting the face of a whoop, so I would guess that you could use a little less compression for that in order to keep your front end more level?? But on the big air, you might want to keep that compression high, or go with a lower compression with an air bump for those big jumps. So does this sound at all right? But you look like you are running just fine to me, and I wouldnt be to concearned about this little stuff untill you have numbers on the side!!

Is that gonna be the whoop section at the D-Day race. If so, YAHOO!!!

I had the same opinion as TRDShaun looks like rebound is fine but the front seems to bang hard I might thik about a bump stop if you cant adjust the shocks upfront anymore. My uneducated opinion. I am gonna be doing the same testing hopefully next weekend in Barstowe. I'll post vids as well..

needs more rear rebound for one... looks like your rear end isnt reacting quick enough to the bump then its wight tranfering to late.

NEVER LIFT!!!!!

greg, i wonder how much is just weight balance? I noticed at the jump contest it would nose dive each jump.

Heres what has to be done; the front needs a little less rebound (especially the last 1/2 of travel, where both coils are working) and the comp. seems to be fine, by letting the wheels drop faster it will allow for more dwell on the comp stroke. As for the rear, i need a little faster rebound (need to drill holes in the pistons for that) and more comp damping in the early stages, that will keep the wheels from coming too far off the ground. One thing to note, the ratio of sprung to unsprung weight, the rear of my truck is very light so i have trouble maintaining control of the axle. If there were more weight back there i could run a heavier spring and that would speed the rebound up. Today i went out there and just made an adjustment to the front rebound (sped it up just a little) and that was a huge difference from how it was working in the video. I cant emphasize enough how important tuning is.
As for the whoop section being part of the course for the event on the 12th, no, its too far from the spectator area and most people have said its just too rough. I built it mostly for testing.

One thing that seems more important to me is how much you have to slow down during hard turns, why not get some kind of swaybar on the back? You can rail it through the whoops but you are loosing lots of time in the turns. It looks great through the whoops though!

Two reasons its so slow in the turns; 1) there was no water on them at the time and they get REALLY soft, like driving through silt but a 60 ft radius turn. and 2) stock 225k mile 4.0, it just doesnt have a ton of power to push the back around. Yes a sway bar would help and that is on the "things to try" list.
