- a butterfly brace like miatas get for the 1Ga, 1Gb and 2G, if im not mistaken and they're already around. These would be amazing for TA and AutoX. Here's the link for a pic:
Flyin' Miata : Chassis : Stiffening : FM butterfly brace
- something like a 2-way or Fully Customizable LSD for the 1Ga and 1Gb
- carbon fibre front and rear diffusers
- c-pillar bar for the 1Ga and 1Gb, if there isn't one already
- maybe a clean widebody kit, or at least some blister fenders to widen the arcs for the 1Ga and 1Gb
