NM Engineering’s Upper Tie-Bar is designed to reinforce the already stellar MINI Cooper chassis. Installation reduces fore and aft, as well as side-to-side chassis flex during spirited driving, which helps to eliminate unwanted geometry/alignment change. This results in better steering response and better handling.
Attention to detail and performance are NM Engineering’s forte and this part does not disappoint. The 6061-T6 aluminum mounting pads will eliminate strut tower “mushrooming” be reinforcing the upper mount and is attached to mounts studs with shouldered long-reach nuts to make sure that the bar and front suspension is secured by more than just a few threads. In addition, when you look at the underside of the pads, you will notice two machined pocket that accommodate the upper strut bearing locator pin on either side while concealing it from view. Finally, the simplest, yet most overlooked feature may be the twin mounting bolts on each side that attach the bar to the mounting pads. Most others use a single bolt to secure each side of the bar to the mounting pads. The problem with that, is no matter how tight you cinch that bolt, the bar can still pivot at that point rendering them ineffective against chassis flex.
