Last year in November Cusco Japan decided to do a few catalogue updates for the March K13 Nismo S trim, this included a various assortment of upgrade suspension braces and parts.

One of the the biggest negatives with me with the Micra was the ride height and to my opinion the sluggish body roll, a big no no for me.
Earlier this year I was able to source a set of Cusco upgrade Anti-roll bars spec'd for the Nismo S March in Japan, to my knowledge Cusco even warned me about fitment issues as they weren't sure if the suspension design was the same from the base model to the Nismo model.
The front upgrade replaces the stock 18mm diameter bar with a 22mm and the rear 15mm diameter additional bar bolts on the rear torsion beam spring cups, there is already OEM holes present on the torsion beam which is the same as the Nismo version.
At the beginning of the summer I installed the set and since then the car handles like another model, nothing like the base setup. I was fortunate enough to receive both rear and front bars at a competitive price since Cusco couldn't guarantee fitment. Here's a few pictures showcasing the details of the front sub-frame and comparison of the stock vs Cusco bar.
The front set included thicker bushing brackets (sheet metal gauge down) and spacer with rubber bushings included.
The rear set included mounting hardware (bolts & lock nuts)
