There is of course the alternative of the factory comfort riser kit, with the top brace. That is the route I will probably go. With the very narrow mountain roads around my house in France, the danger is with a truck coming towards you, you have to pull fully into the right side of the road. In my LHD car, you cannot see the right hand wheel, so it is easy to get too far onto the edge of the tarmac. This is often really bumpy with tree roots, which can then throw you towards the oncoming truck. My brother has changed to RHD for his Mk.2 M3W in France, as it makes it easier to place the car on narrow roads.
