I am trying to decide between a BP and MSMB. I am just wanting to improve feel and handling on my daily drives. I don't autocross. I have read more than one review that indicated that the MSMB is an improvement over the BP but that it bottoms out on speed bumps and scrapes the ground when entering certain driveways. Is this scraping issue something that I should expect if I choose the MSMB? Does yours?
