That looks like it's designed to have the same contact footprint as the rubber bushings, meaning it's not stressing anything any more than the stock design does. Having a smaller contact footprint like that also doesn't stress the bolt anymore as the bolt's stress is purely axial, but changing the footprint does change the stress profile between the bushing and cradle/frame. While a larger surface is technically more distributed it doesn't imply that it's better. The OEM parts are tested to show that they can last the life of the vehicle without failing and may have been designed that way to make the load paths better follow a reinforced part of the cradle vs having a larger one that potentially loads a non-reinforced section. Not to say that the BMR one will cause a failure, but personally I'd be more comfortable with the OE design because I know that one's designed with the full system in mind instead of just going based on what "looks right."
