If your Highlander has more than 75,000 miles then you need to change the struts / shocks front and rear with new Toyota parts to maintain like new levels of high speed cornering capability and ride control. As the miles pile up, Toyotas tend to ride more softly and lean more in the corners.

However, it might be that the Highlander is simply a too softly sprung vehicle to satisfy you if you are an aggressive high speed driver. The Infiniti FX35/45 is a better choice for hurried drivers, but it doesn't absorb the bumps as well as a Highlander can.
