Motorway speeds feel wobbly and floaty

[Kithmo]

If it feels like it's oversteering then lower the front tyre pressures down to the recommended 2.2 bar and leave the rears a little higher, as you've got them.

Think about the weight distribution.....it will feel different just because of that. All the weight is now central versus front. If you have driven either mid engine cars or rear engine cars you will know the difference, but very few have.
