In their September 2003 publication, Excellence magazine identified Lake Underwood as Porsche's "quiet giant" in the United States and he is among the four drivers, including Art Bunker, Bob Holbert, and Charlie Wallace who are identified by the Porsche Club of America as having made Porsche a giant-killer in the US during the 1950s and early 1960s. Notable early successes in the US also included an overall win in the 1963 Road America 500 for an under-2-litre RS-60 driven by Bill Wuesthoff and Augie Pabst.
