JConcepts React 2.2″ 2wd & 4wd rear open cell inserts
JConcepts have come with their React 2.2″ 2wd & 4wd rear open cell inserts. One common adjustment made during carpet and turf racing is altering the rear tire insert. One of the recent trends is utilising a narrower rear insert while racing on carpet and turf, which has shown to produce different handling characteristics. The narrower design leaves more room for sidewall plunge providing more side-bite. In addition, the insert is low-profile, tight, and compact so the tire maintains its small shape for quick and nimble transition and acceleration.
