oversteer after a drop?

I'm not super stoked to find out the hard way if I've created a problem for myself. Thanks for reading. I always learn a ton from you guys! Here's what I've done:
Working on my '80 C35 SRW. In an effort to give it a mild drop and to make it ride smoother I removed the overload and 2 leafs from the rear spring packs. Still have 6 left. Also used a modified drop shackle. No rear sway bar. ..yet. I'm planning to use Firestone Ride-Rite bags for when I'm loaded. Probably won't load more'n 1000lbs.
In the front I used C10 springs with one coil cut out. Has a 1 3/16 factory sway bar in front.
Like an idiot I didn't get good measurements before working on it, but I think this has given me about a 3/3 drop. Right now it measures 1 inch of difference front to rear.



I've done it like this because if I don't like something I can return everything to the way it was.
The way I figger is that I've removed a bunch of stiffness from the suspension, which is what I was aiming for. I'm just not sure that I've done it equally front to rear. I read the over/understeer depends on how the suspension stiffness is matched, front to rear. I don't want to drive it much yet because negative camber needs correction, but I want to rebuild the front A arms with offset UCA shafts. I still need to think about which shocks.
Question is:
Do you see any problem with oversteer here?
Seems that a rear sway bar would replace any torsion that was lost in removing leaves, but would it replace too much, as it's relative to the front?
Am I anywhere close to understanding this?
Thanks again, Mick

Re: oversteer after a drop?

Are you saying that the back end steps out on turns?

I've only drove it around the block so far, so I don't know...yet. I'm just trying to anticipate how it'll behave based on what I've done. Maybe I'm just thinking it to death. Probably needs a good spirited test drive on a wide road!
