New Patent Pending TAC design magnetic mirror mounts is the answer to those pesky shaky mirror mounts. You will no longer need to use strings and cords to attach the mirrors or suffer from vibrating mirrors while you ride especially during highway speeds. The awkward attachment from factory is not the best design, popping off an RT mirror will make you cringe each time you do them. After a couple of times the mirrors start to get shaky and it will never be the same like new. TAC Design came up with a great design! Using 3D software and shock data, they were able to determine the amount of force these mirrors sustain and came up with the right magnetic pull force. The housing also makes it safer to handle and will not break and shatter if accidentally dropped. The slotted mounts allows for easy adjustments and uses all factory screws. Installation is also a breeze, remove the 3 plastic plates from the mirror and mount the new metal plates in place. The new plates are coated for longevity and also prevent corrosion. The flat magnetic design means closer and tighter tolerance to the body and less outward pressure during impacts. The result is a superior product with a clean design and no interference with the factory gauges. One of the best mods you can do if you own a Spyder RT.
