Little Chassis Help

Here is a graph and a launch in slow motion. You can see it dead hook, then get on the tire. I did have a 5400 chip on the starting line. I'm in 5000ft or air BTW. S/G index is 10.03

Where would you go with it?

Wish you had a shock travel sensor.
The rear shocks look too loose both ways.
Front end shock extension is way too loose.

I'm not sure about the front, but yea the rear is 3 from loose both ways. Just a starting point..

It's pitch rotating so fast that it's killing the back tires. Slowing down front end travel or adding nose weight would help a bunch.
Just ten pounds out front would help if you can't slow down the shock travel.

I will pull the front end tomorrow and see where the front Strange struts are set.

Would you leave the 5400 chip?

I would leave it for now. I think it would probably be better with lower chip like 4400 but I would get chassis right first. I agree with tightening up the shocks to see what that does.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

I feel foolish. I've been at 3600 due to tire shake and went up to 4600 last weekend. I haven't tried anything over that yet.
