I just did a practice even two weeks ago, I added some caster by turning my camber plates sideways - and since I needed a little more clearance on the rear of my wheel well I also shortened my tension rods just a little.
I didn't get a chance to get a real alignment after I did this, so I eyeballed it, I believe it was toed in just a little from how it was handling. I toed it out some at the track and it felt better but I was having an issue with transitioning between turns.
The first turn would feel awesome like I had a lot of grip, then it would basically tank slap and become uncontrollable when I'd transition. The very most I could manage was linking three turns before I'd spin out, and that involved a shit tone of input on my part. I am attributing most of that to my lack of having a real alignment (I checked my rear arms when I changed tires and my freaking traction arms were loose, I guess the alignment guys - or me - forgot to tighten them down all the way, so who knows how my rear alignment was).
Any suggestions on correcting my instability issues? Obviously I need a real alignment, that will probably reveal a lot.
Here's a picture, you can see the front wheels really well in it...
