It's super easy to induce oversteer once the sway bar and endlinks are installed. Lift off the gas and graze the brakes going around a highway exit and the back end loves to come out. You go really fast and simply lifting off the gas in a corner will make the ass end step out. So fun.
White line 22mm rear away bar with accord end links is the setup I'd reccomend.
Any shop with basic tools can install it. It shouldnt cost more than an hours worth of labor. Maybe 50$
Yes a rear away bar makes the backend seems much more responsive. Feels way tighter.
