After Nathan, Terry, and Surtees, the fourth participant in this project appeared at the end of 1968 with the American actor James Garner.
Terry designed and built the first four chassis in his small workshop in Poole, with logistical support from Surtees.
John Surtees had brought the Garner back to Europe and used the cars, still with Chevrolet engines, under his own team leadership.
David Hobbs set the fastest lap time of 1:30.6 in qualifying and put his TS5 on pole position.
At the third round of the season at Brands Hatch, there was the second pole position, this time secured by Trevor Taylor.
Hobbs celebrated the first race victory at the sixth round of the season at Mondello Park, where he was waved off as the winner after 84 laps in front of Mike Hailwood in the Lola T142 and Alan Rollinson on a Brabham BT30.
A winning streak was followed by Trevor Taylor, who won back-to-back races at Koksijde, Zandvoort, Snetterton, and Hockenheim.
In 1970, the first win of the season was not until the ninth race, when Trevor Taylor won ahead of Peter Gethin in the revised McLaren M10 and Frank Gardner in the Lola T190.
For this purpose, the vehicles had to be shipped again and again by air freight be transported back and forth between the UK and the US; this was also a not inconsiderable financial effort.
In the same race as Goth, David Hobbs also started in the works car, but dropped out on the second lap due to a defect.
Four more wins of the season followed for Hobbs, including a double at Mont-Tremblant when he won ahead of Andrea de Adamich.
As in Europe, Surtees could not win the overall championship standings in the USA, despite strong races and successes that could be counted, since the team entered the series too late in the year and Tony Adamowicz's point advantage in the Eagle was therefore uncatchable.
While John Surtees spoke of 15 vehicles built, only ten TS5A can be fixed despite the confusing chassis stories.
This is mainly due to the lack of assignment of the cars delivered to Royal American Competition Enterprises Fred Opert Racing and Doug Hooper, which leads to great potential for confusion.
