Default New UMI Suspension Setup

I'm not a suspesion guy, this is my first time setting all this up. I added a new UMI; drag bar, short TA, LCA's w/relo brackets, and panhard bar along with a Moser 12 bolt. My question is before I added all of this my car would launch at the track lifting the front end nicely with no tire spin, now the front barely lifts, the back actually lifts along with the front, is this the way it's supposed to be? I always thought you wanted the back to sqat a bit to help with weight transfer.

That is exactly what you want it to do, it is called anti-squat or rear end extension. Are you running a radial?

What's your pinion angle? What are the LCA's set at? Has the 60' or 330' picked up any?

Pinion angle is -2 and the LCA's are in the lowest hole on the brackets. I'm thinking of trying it without the relo brackets. My 60' is the same but I converted to a 4l80e so hard to compare. The tires are not spinning even with higher pressures. I mistakenly forgot to check the pressure before my first run which had street use pressure of 28lbs, still didn't spin.
