The wide margin by which the Texan captured the championship is perhaps a bit misleading because it gives little indication of the effort that went into the season's campaigning. Jim and his Chaparral II participated in all the U.S.RRC races, not missing a single one of the 10 events that took place in all corners of the country. This not only made Hall the most widely traveled competitor for the driving crown but also endeared him to the officials of the Sports Car Club of America and to the several promoters, who needed a first class team like the Chaparrals to give a bit of class to the series.

Second in the final standings came Bill Wuesthoff, Milwaukee, who collected 36 points from three class firsts, a second and a fourth in only six starts. Driving an Elva-Porsche for the Robert Bosch Corporation team, Wuesthoff won the 2-liter class at Greenwood, Mid-Ohio and Elkhart Lake.

Third place went to Charlie Hayes, Chevy Chase, Maryland who missed second place by only one point (35 to 36) after three class firsts and two thirds out of nine starts in an Ollie Schmidt Elva Porsche. 

In the manufacturers' championship section of the U.S.RRC series, AC Cobras were literally unchallenged all season long and scored 10 wins in the 10 events for a perfect score. Porsche, running in the under-2-liter class, finished second in the standings with five class wins, a third and a fourth. Third in the final tabulation came England's Lotus-Cortina GT, which got two class wins, three seconds, one third, one fourth, one fifth and one sixth in nine starts.

In both the drivers' and manufacturers' championships, points are a warded by class (over and under 2000 cc) but the overall winners are those with the greatest number of points regardless of class.
