Car Feels Unstable Under Power

[BmacIL]

The bump steer through corners is just mildly aggravating, wheel sawing back and forth and constant correction to hold a line. Didn't change when I went to BFG Comp 2 A/S from the OE PZero summers. I've not yet had an alignment done though, but lots of mods in the rear IRS/Diff.

It's alignment and bump steer.

I have the b/f Goodrich all season and it's a excellent tire with great traction

Been having the same issue with the factory tyres. The service rep recommended to replace the tires.
I've only had them for 15k miles so I'm looking for alignment or other possible reasons for the issue.

I know like car color. Opinions can vary, but what would be the round about specs for an alignment?

Front
Camber: -1.7 deg +/- 0.2, even both sides
Toe: 0.00 deg per side, even both sides, or just slight (0.02-0.05) toe in

Rear
Camber: -1.4 deg +/- 0.2, even both sides
Toe: 0.10-0.12 deg per side

That's an excellent spirited street alignment.

Thank. Going to print this off and bring it when I get a alignment.
