This victory created the formation of the Border Reivers team, with Jock McBain who owned a local garage in Chirnside, Alec Calder Jim’s brother in law, Scott-Watson as secretary and Jim the main driver. McBain, Calder and Scott-Watson was also instrumental in organising motor racing events at the race tracks of Winfield and Charterhall where Jim would hone his natural talent. Less than a year later Jim set the record at Full Sutton in April 1958, as being the first driver to average over 100mph in a British sports car race in a Jaguar D-Type.
Less than a month later on the 18th May 1958 Jim had his first taste of continental racing at Spa-Francorchamps, Belgium. The year ended with Jim competing against his future boss Colin Chapman, Chapman narrowly beating Clark to the chequered flag both driving Lotus Elites.
The following Summer of 1959 saw the Border Reivers team enter the Le Mans 24 Hours. Jim and partner Sir John Whitmore drove the Border Reivers entered Lotus Elite to 2nd in class and 10th overall, a stunning performance which raised a few eyebrows. So impressive was Jim’s driving that Aston Martin signed him up to lead their Grand Prix team. Unfortunately, a race worthy car was never produced so Jim, who at this stage was already signed by Lotus to race in Formula Junior switched all allegiance to Lotus. 1960 was a significant year of success, Jim won the Formula Junior Championship and competed in 4 Grand Prix for Lotus and achieved his first ever Formula 1 podium with an impressive 3rd at the Portuguese round, this was despite driving a car that had been rebuilt after practice and was really only held together with glue and masking tape! He also claimed a 3rd placed podium overall in the Le Mans 24 Hours with the Border Reivers in an Aston Martin DBR1 partnered with Roy Salvadori.
