Continuing development is critical to performance, the team at JConcepts have developed a new option for tire sidewall support. During high traction or loaded conditions, tire sidewall deflection causes oversteer and inconsistency with driving performance. By adding the inner sidewall support adaptor and gluing it into place, the sidewall effectively becomes much harder and allows a driver to enter smoother arcs and radius turns on the race track. Already used in competition, the sidewall support pieces have shown to work on glued, sealed, or naturally grippy surfaces where traction rolling or oversteer is an issue. In addition, when conditions are rough, bumpy or dusty, the additional support drives smoother and with more consistency.

At the Southern Nationals, Spencer Rivkin, in conjunction with the JConcepts race team, installed the adaptors into the Reflex tires helping Rivkin to one of the top steps on the podium. On the extremely eroded and loose surface, the supports were added only to the inside of the outer sidewall and tack glued into place. The ultimate option to a massive array of tires gives JConcepts users an advantage and a larger setup window to tune in to any surface. JConcepts, established in 2003, is truly World Proven Innovation and Design.
