Um, as close to the green zones as possible. Side hop is not just an alignment thing, perhaps inspect rear bushings(toe especially)? Are you lowered? Did you do the SUM calibrations?

No low :/ yes sum cal. I heard that setting something in the rear to 0 renders side hop not present or very little.

When I first started driving the car a little harder it felt like I had no control of the car. So I started focusing on suspension and alignment for the last 3 weeks. I had side hop. Now I don't. I did the following modes in this order. But couldn't tell you exactly when it went away.

added ebach pro sport lowering springs.
loosened rear side walls by dropping tire pressure: front 40psi, rear 34psi
Then re-aligned
0 toe front and back
-0.25 to 0.5 front camber
-1.0 rear camber

Side hop and no meaningful steering input.

added ultra racing rear tower brace.
lowered front another 3/8 inch to regain stock rake
added IPD racing spec 25mm rear sway

Then re-aligned
0 toe front and back
-0.25 to 0.5 front camber
-2.5 rear camber

changed rear to 265/35/18 to loosen rear sides walls more
I could still feel the front bouncing around through rough corners

added IPD race spec front 25mm front sway.
added untra racing front tower brace

Car still flexes more than I like. But now the car feels under control through rough corners. And no more side hop. I'm going to play with front and rear lower braces next.
