Horrible handling

Maybe it's me. The tires are hardly broke in. The hole course was a off camber track. Never done that much. So I'll keep a open mind. Maybe my accident has me mind boggled.

You just changed rear tires? Street tires or race tires? Same brand/model/compound as the front? That could be the case. Was it only when turning a certain direction? When the rear broke loose was it snap oversteer or gradual/controllable? Was the turn-in good because the rear rotated easily or because the front was sharp? How was it under braking?

If it was indeed driver error it was likely a case of going too slow in and getting on the gas too early/hard. Without messing with the traction arms/toe curve I am going to say it's likely not due to the small toe-in.

Same tires front and back. AD08's. It was gradual and controllable. The turn is was what seem sharp and rear rotated easly. I was running a 265 up front went to a 275. Braking was more than fine. Maybe it's such a dramatic change on all levels that made it feel wild. I was definitely slow in a trying to push it out hard. I guess my nervous are a wreak from my incident. I've been beating myself up for months about it so........

I am going to go ahead and guess that its a combo of getting on the the gas too hard/early and rear sway was too stiff for the new setup. Toe issues usually end in a more snap-oversteer or unpredictable feeling. I don't think it was the tires. The AD08s are actually best on their first heat cycle. Race slicks when cold/brand new can be a handful but usually not true for street tires.

Sways are on full stiff now. I'll back them down check my alignment again in case and grows some balls. Lol. Thanks for the advice Mike.
