Center Section Recommendations: For an all around great performing bar, we highly recommend choosing the 0.120″ wall thickness center section. It really hits a nice range of adjustment for this chassis. It can get close to the softness of the other conventional ND bars on the market, yet has the ability to sweep to a much stiffer range (something that is very necessary to provide speed in quick transitions). The 0.120″ bar is also our recommended bar for SCCA CS trim vehicles, allowing competitors to tune the chassis around many different surface conditions, course designs, and driving styles. A lighter 0.095″ wall center section bar is offered for those who prefer a softer range of sway bar rates. The 1.25″ O.D. x 0.095″ wall center section is still no slouch. If comparing to all the conventional bars on the market available for the ND today, this bar can actually hit a roll rate range of all of them combined; it just cannot go much stiffer. Lastly, we also stock a stout 0.188″ wall center section bar. This bar is recommended for vehicles using 235mm wide or larger tires with 200TW or less, which of course includes SCCA STR prepped vehicles.
