TrackArt 4pt Bolt-in Roll Bar Cage | Nissan 370Z Z34



Other cages on the market struggle with fitment issues causing very strict seat restraints and/or head clearance.  Look no further!  Whether you want the next step up in safety above a harness bar, or you just want the additional “wow” feature at a show, this is the cage for you!

Each cage is hand fabricated and test fitted in the shop Nissan 370z prior to coating, so you can ensure your’s will fit perfectly!

    • Lateral bar (from top of main hoop diagonal to lower passenger side of main hoop)  – This lateral bar is considered a key component in supporting the main hoop.  This bar does restrict how far back the passenger seat can slide.
    • X-Brace – Adding rigidity to the strut towers, we chose the sleek look of the X brace over a standard strut brace.
    • Standard color options listed come in gloss.  If wanting matte or textured please notate at checkout
    • CUSTOM COLOR – Please locate color code at Prismatic Powders and list the code in notes at checkout***
