You can significantly reduce front end ploughing by introducing more camber on the front end. With stock camber, you will only be using the outer 2 inches of any tire width (when cornering hard). Look at your tire wear after a hot run to confirm this. If you still have any shims in the front, consider removing them. If it still isn't enough, there are other solutions sold which allow a greater camber adjustment.
