Off-topic:
It's inertial mass and velocity that counts. Landing gear in 3302 also counts on shields in most cases so can be much more fragile than you expected. It's you choice to not use them. Landing gear and all shock-absorbant mechanics are the parts of yours conda hull.
Haven't study this question so far, they can be installed. Don't know. If no, there will be scratches at least - at any speed, also below 0.1.
taking into account conda mass - 400t (?) we have 0.05MJ (if I calculated well) absorbed somewhere in your hull/suspension. Not so many. But may be that kind of "damage" is rather effective=)
Come on, if you want to play the realistic approach, how do you explain that helicopters doesn't need a shield to land under 1G those days ?
