so it's a secret as to what the shock's extension setting was on that pass? :confused:

On that pass I had 7 degree of timing pulled out, front travel set to full (5.5") and front shocks were 10 or 13 clicks off soft (31 clicks total from full soft to full stiff stiff rebound)

One of two things were happening that day to me, either it went straight up as in the pass in the picture or with things tightened up to control wheelie it was blowing them off. There was no in-between whatsoever. No fun being on the starting line wondering if it's going to be a pedal fest or a burnout contest.

I want to be able to just set the suspension up to "let it eat".

sure looks and sounds like your entension was too soft.

all I can tell you is that with DA Afco's at all four corners and adjustable travel limiters you CAN tune the wheelie to whatever you're comfortable with.

I can also tell you that the shock and travel limiter settings that work in average air will have you going straight up in good air.

Once you get the rear shocks set right so it dead hooks in good air on a colder track, all you need to do is stiffen/tighten the extension on the front shocks on good air days.

Find your usable range on the extension and stay within it.

On good air days, I start with the front shocks at full stiff on extension and go no more than 1/8 turn from there.

FYI, you can also tame the wheelie by swapping out your front springs to a stiffer spring.

I've often wondered if I need to go to a stiffer front spring. The front of the car can easily be topped out by hand lifting it. Front weight is 1900 lbs if memory serves me correctly. I have shimmed 180's in there now, it may be time to go to 200's.

are these shocks coil over?

How many runs on the slicks?? Tire press.We chased a hook/shock settings and then put new tires on and it would hook in a car wash again,with shocks set tight

I think the shock body is threaded. Honestly I can't recall.
