Msport has nothing to do with this. There's only 2 things that can be wrong here. Either your wheel/wheels are warped or your tires arent high speed balanced. Sometimes your tires have imperfections as well. You usually see this in cheap Chinese tires where it's impossible to get a perfect balance. Is your car new or preowned/CPO? I would head to the dealer and have them road force balanced and check each wheel/rim for imperfections. Ask them to try to get each wheel as close to 10lbs of force as possible. Vibrations are not normal on a new car and then telling you this is just BS. Worst case, if they refuse to help, take your car to a reputable high performance shop that specializes in track cars for balancing.
