Its working pretty good... more clamps on the front
segments will help stiffen up the fronts... then either
stiffen the extension rate on the rear shocks or put
better shocks on... if you clamp the rears that tends
to fight the front segments... the front is trying
to lift and the rear tries to pull it back down...
the shocks should control the lift rate.. not the spring

Is it me or did you short shift from first to second against that Camaro. It looks like you was pulling him in fast just before the stripes.
Car leaves very swell. I've been on the fence about Tri-C launchers, but maybe this may entice me. I'll test a little with what I have and see if Tri-city gets my nod.

Are those tri-city shocks adjustable?

I am betting it is pretty close to optimal now; even gradual separation, settles down after low gear well. Those slicks are radials, correct? No or little wrinkle with radials. SS springs are going to wrap up some, and at low speeds I don't see an issue with the angle being a bit high for the first 50 feet or so. Take a look at the separation on my Dart with SS springs circa 1985. Now that is a bit much! But it never hurt any trany or reaerend parts.
