Among the more notable entries for this weekend’s SVRA U.S. Vintage National Championships at Circuit of The Americas are father and son Geoff and Matt Brabham who will compete in a pair of 1971 Brabham BT35 Formula B cars.

The cars’ owner Ron Hornig will compete along with the pair, the COTA FB field boasting more than 15 entries so far, with at least 12 Brabham chassis on the entry list.

The spaceframe single-seat BT35s, of course, carry the name of the family patriarch, the late three-time Formula 1 World Champion Sir Jack Brabham.
