Description Reviews NM Engineerings Upper Tie-Bar is designed to reinforce the MINI Cooper chassis reducing fore and aft, as well as side-to-side chassis flex during spirited driving. This results in better steering response and better handling. The 6061-T6 aluminum mounting pads will eliminate strut tower mushrooming by reinforcing the upper mount and is attached to mount studs with shouldered long-reach nuts to make sure that the tie bar and front suspension are secured by more than just a few threads. In addition, when you look at the underside of the pads, you will notice two machined pockets to accommodate the upper strut bearing pins on either side. NMs' tie bar also uses twin mounting bolts on each side that attach the tie bar to the mounting pads, assuring against chassis flex. Will fit all Gen 2 "JCW" or "S" models except Countryman.
