The Five Great Indy Roadster Builders From 1950 To 1960

With the 101st running of the Indianapolis 500 a mere two weeks away, we are reminded of the time when roadsters ruled the brickyard and 80 percent of the cars were built by five car builders in the Los Angeles area – all within 25 mile radius of each other. In 1958, all 33 cars in the field were built by these five southern California chassis builders.

There were other roadster chassis builders, most of which hailed from southern California during this time; Myron Stevens, Lou Moore, Jud Phillips, Bob Pankratz, Johnny Pawl, Lou Bromme, and the great Emil Diedt. Even with these famous fabricators and craftsmen, the top five most recognized as the dominant builders of the post war Champ Car period were Quin Epperly, Frank Kurtis, Eddie Kuzma, Lujie Lesvosky, and A. J. Watson.

Kurtis Kraft

Kurtis Kraft, led by Frank Kurtis was the most dominant chassis from 1950 to 1960 with 194 of the 363 cars that competed in the great race over that period. Kurtis Kraft stopped producing Indy car (Champ car) chassis for the race after 1960. Kurtis’ shop was first located on Alger street, between Sequoia and Baywood, then relocated to 1107 E. Colorado in Glendale. Almost all of the chassis built during the roadster era were variations of the Kurtis Kraft design. Over 53 percent of the cars that raced the Indy 500 from 1950 to 1960 bore the Kurtis Kraft name and serial number.

Eddie Kuzma’s Shop

Eddie Kuzma’s shop fabricated Champ car chassis from 1951-1960 on Budlong avenue in Los Angeles, at the corner of El Segundo and Budlong. The 36 Kuzma chassis that participated in the Indy 500 in the 1950s decade represented ten percent of all Indy cars over that period.

Watson’s Roadsters

A.J. Watson’s shop started as a small fabrication facility on 1903 S. Brand in Glendale before moving to a larger small shop at 421 Palmer street in Glendale around 1958. Watson’s Roadsters were basically copies of the Kurtis Kraft chassis with some tweaks that Watson had perfected to make the cars his own unique breed. With 21 chassis participating in the 500 from 1950 to 1960, he represented six percent of the total with race winners in 1956, 1959, and 1960.

Quin Epperly’s shop on Raymond and 135th street in Gardena represented five percent of the cars over the same period. Opening his own shop in the mid 1950s after working for Frank Kurtis for years, he joined George Salih working with the laydown roadster concept. Epperly’s laydown roadsters were well know for their balance and aerodynamics, especially in cornering. Unfortunately, the laydown roadsters never won the great race under the Epperly name.

L.A. Lesovsky Race Car Engineering

L.A. “Lujie” Lesovsky, the fifth of the great five roadster builders, and probably the one that is most responsible for modifying chassis built by the other great roadster builders than building his own chassis. His shop was located on 5275 South Figueroa Blvd. in Culver City. There were 15 Lesovsky chassis during this era, which represented four percent of the Indy 500 cars during the decade.

The Final Numbers

In total, 289 of the 363 cars that raced in the Indy 500 from 1950 to 1960 came from these five builders. This was a time when any chassis that complied with the rules could be used to qualify and compete in the race. When the 101st Indianapolis 500 gets underway, there will only be a single chassis manufacturer, by rule and not by car owner choice. It is hard to tell if a rule is really needed based on the results of the roadster era. Car owners tend to select the best and the choices remain a tight group to select from.

It would still be nice to have options though.
