my saph is a little bit unsteady on the road wen i go over 85 ish and above , wen i would hit a bump it would just unsteady it a tad bit - like the steering is very light on it , i have ahmed springs and konis , poly tca arms and all the rear is poly bushed , the same road i can take my astra gsi out on it at keep it planted at 110 or more no bother good and steady , anyone have any suggestions as to why the car gets this way with speed - wheel bearings and track rod ends ar all perfect from wat i can see
