My bet is that your oversteer prior coilover installation due rear toe being out of whack, maybe even toe-out (that shouldn't be there, as even stock rear toe "should" be slight toe-in). Or general mishandling with drivers inputs or choices for almost intentional inducing of rear grip loss for fun sake, when car is loaded in turn or on low grip (eg. winter/in wet/on gravel).
I had more than one alignment done on the car when it was stock. On say a 270 degree on or off ramp, at the limit of grip, the back end would have come around before I plowed off into the grass. On 215 tires and more so on 245 tires. At the car's stable limit, an FRS will spin out before it full on understeers.
