JQ Products optional centre shafts

One of the unusual features of THE Car by JQ Products is its centre differential, which has 8mm of front/rear adjustment in the chassis which can have a significant effect on handling. The standard kit comes with central to weight forward transmission components, ideal for tight, technical stop/start type tracks. If the full extent of its weight-back set up is required, usually for fast open tracks, then the optional weight back centre shafts must be used. The set includes the 90mm and 104mm option weight back dogbone centre shafts.
