Hello group, was wondering if anyone can help me with a problem I have with my 2016 discovery sport. When Driving at speeds just above 90 km/hr to about 100km/hr I start getting heavy swaying left to right, almost the same feeling as aquaplanieing but on dry surface??? Tires are still good 50% pressure is spot on , wheels were balanced and alignment is good!! Any advice would be much appreciated. Thankyou
