A 10" high speedbump is severe, most Mogs will catch the crossmember at only 4" - 5"

The SSL can be set up during install to give an increased ground clearance, did you specify this ? otherwise it drops the ride height (the overall total difference could be around 40mm) -20 if dropped / + 20 if lifted, unfortunately it's almost a full stripdown to swop the spacers over
