Category Objective
The purpose of the Xtreme (XA/XB) Category is to attract automobile enthusiasts interested in autocross events with street vehicles using minimal rules that allow for creative modifications with limited restrictions. This category is intended to appeal to regional/local competitors who would like to compete with a modified car on street tires but would otherwise be classed in high-prep race tire categories.
This class, unlike many other classes, is relatively unrestricted. Any modification is typically allowed unless specifically stated otherwise in the rules. This is unlike other classes that disallow any modification unless otherwise specified in the rules.
