Go square and FSB.

Recommendation for RSB is if you do nothing else.

Something else that also makes a BIG difference is alignment. If you're completely stock everything, max out your front camber, which will probably be around -1.5 to -1.8 on stock adjusters and height. Rear camber, match the front.
Front Toe should be 0.
Rear Toe should be somewhere around 0.10 to 0.20 degrees total, less toe for better turn-in and tail happiness.

Ideally for summer tires and auto-x/track driving, you'll want to get at least -3.5 to -3.0 Front camber. Rear camber should be dialed down to around 03. to 0.5 degrees less than the front (more front camber than rear camber - always). You'll need some sort of offset bushings, camber ball joints, or upper control arm changes to get -3.0 up front.

Okay sounds good, I’ll start with an alignment then before I do anything. I’m bone stock right now. (with a Mugen wing but I doubt that does much on street)

A mugen wing will make a change in bias

Really? On a stock car with a softtop on the street?

I also have an OEM AP2 lip, but I imagined both of these have near zero effects until you’re going hard on track

For the track, for lap times, absolutely

For his use case, his desire for more rear bias, this seems like exact opposite of what would achieve his goals

why?

That quoted post seems like it would definitely make the car ‘sharp.’

A few minutes ago @ragtophardtop wants less tail happy performance. He's on a modified Ohlins suspension but there's a solution between the lines of his note. Contact him here so we can all learn.

A front swaybar (meaning stiffer than stock) increases front bias. More understeer. More stability. Better lap times. But less fun. Less lively.

The common advice for pur cars of wider front tires, and a front swaybar, is good practice for track. Also good for people that learned to drive on fwd, more comfortable w understeer.

But the op said he wants less understeer. Wants more lively feel. Does autox, but not track.

Recipe for that is not the common front swaybar and wider front.
