It can be mis-leading to purely look at what is the lower… gearbox or chassis.crossmember. I have had many hits on the crossmember but rarely on the gearbox. This must be because the gearbox is nearer the front wheels, so gets a better elevation when traversing sleeping policemen, whereas once the wheels are over, the crossmember then becomes the prime target, with no help from front wheels. Traversing at an angle sometimes helps but not always successful.
I have been tempted with bash plates but of course it reduces the ground clearance even more. When my tyres come up for renewal next year I am going for 65 profile all round instead of the standard 60. I am pretty sure it won’t noticeably affect gearing, and speedo is easy to adjust if needs be.
