Front: -1.4 degrees camber and 0 degrees toe Rear: -1.0 degrees camber and -0.10 degree toe. I'm running Hankook R-S3 285's on all four corners. Yes, pretty much at stock ride height. I found five pictures that were take at the same event. The were not taken when I'm seeing this behavior but maybe they can tell something about how the car rolls...

Do you run Autocross in Competitive Mode (two presses of the TC button)? If not then I can see where inside wheel spin could set off traction control and create a more noticeable interuption. If you put it in competitive mode then the Traction control is disabled but Stabilitrak is still active (at a reduced interference level though).
if it's just the rear inside wheel spinning easily (and not actually lifting off the ground) then I have heard of others having that issue before. Dropspeed was having that issue on road courses with his 1LE suspension set up. I beleive he has a Z/28 style diff (helical) in his 1LE now as well as the Z/28 suspension set up. I don't know if I've seen a report back from him on whether or not this resolved his inside wheel spin or not. Maybe you want to send him a PM and ask him about it.

Sounds like Dropspeed's problem is definitely familiar. I'll PM him for sure.

It is semi-Popular to get the eaton for that inside wheel. Also there is some improvement to be had in your alignment for sure to help with rotation. JusticePete has a bunch of posts about castor and camber and toe.
Could have sworn the z28 set up is supposed to be lower. Cool car by the way goodluck.

The car ended up being higher than I had expected. I even had my alignment guy redo the bushing clocking to make sure there wasn't an issue there affecting the ride height. Sent from my SM-G920V using Tapatalk

+1 I had same trouble with what I thought was the rear wheel lifting but it was because I was upsetting the car too much. I softened the front and let the front tires "turn" and roll the course better and let the rear end catch up to power out with about 10-15 degrees rear slip to turn the back end. Smooth in and smooth out didn't seem faster but it did make my runs faster.

an alternative to the Z diff would be to install a trutrac, that's not cheap either though. just another option

Angle upwards or through a gutter where you van loose traction. You cant go to stiff on shock settings if you have coil overs, with my Pedders supercars I keep them in the middle or upper middle range, more is no affect, softer not enough, and thats with 450/560 spring rates. Cars have to be controlled but also be abpe to get wieght onto the front tires, then also be able to swing that back end around. I find close to neutral is best |

Sounds like it's time to save some pennies for a Z/28 diff.

Front settings
I have my front sway bars set as soft as they will go. This photo was from this past weekend and you can see how much my front tire tucks under nicely and I get good front bite , but that does cause me to get some rear oversteer but only if I am too aggressive with the right foot. I personally like the way the front leans over but some my prefer a stiffer setting up front. Just sharing a different view of the front attitude on my Canaro.
