Caster and Camber Change During Turning

So, I've been looking over some of my pictures of my Z drifting and I see this:






Heavy camber gain/loss at full lock. It became more apparent after I increased the steering angle with the tie rod end spacers. Now, under normal road racing circumstances, the camber gain is good. Outside tire gains more camber, inside tire loses camber, to flatten out while cornering, for more grip.

But while drifting, it has the opposite effect. At full lock, the camber change almost seems to jack up one corner of the car, and I'm riding on the shoulder of the tire on the leading wheel, as shown in the first pic. And the trailing tire almost run entirely on the inside tread.

I know caster has a major effect on this, but is there any other way to reduce this effect so much? For reference, stock caster specs for a Z are around 9.5-10.5. And I'm running about -3.4 static camber. Running that much camber to compensate for the camber lose of the leasing wheel. However, I see S-chassis cars having this same effect. I'm also kind of fond of how the steering self centers with so much caster dialed in. Counter steering is very quick. However, I mainly just want to flatten out the car a bit more and stop riding on the edges of my tires so much.
