Only people who can comment on weather it’s an issue or not is the people who make and sell them. If there was an issue but as there on lots of cars there isn’t lol but if there was a problem would have come to light and they would have been asked for a refund or solution. They obviously fault about them and designed them that way for a reason. Plus once bolted up to the floor the bush sandwiched round the beam 100% sits square to the floor on mine so is bottled up without issue
