Was the bump steer noticeable to you while driving?
Yes. The car feels "odd" if nothing else.
These cars hide it pretty well between all the bushings and heavily over-assisted steering.
The bigger problem is the stupid tire wear due to the overly-active toe. I don't expect it to be quite this bad on a considerably stiffer suspension, but any kind of stock springs or lowering springs are soft enough rate that you're using all of +/-1.5in of wheel travel on a pretty regular basis. Every little bump, dip, pothole, turn, etc the toe is changing wildly.
No alignment toe settings will fix this.
Now some is likely from spinning the inside tire on corner exit on track, but I’ve never gotten wear like this before. Is it from more camber? Potentially yes. So take this FWIW. Other factors CAN be at play.
My tire wear at stock ride height with 034 camber mounts + offset bushings was REALLY good. I’ve been chasing suspension problems ever since deviating from that formula. More camber would be great but for a dual use car it worked really really well.
I think it might be worth playing with suspension packers to extend the bump stops closer to contact for autocross, etc. it’s basically supplemental spring rate that’s easily removable if need be. And cheap to experiment with. If I do go back to stock or stock-ish springs I plan on playing with this idea.
