Brabham BT4

Here are three cars approaching McLean's Corner in the HGPCA Race for Pre-1966 Grand Prix Cars at the Historic Grand Prix Cars Association's International Historic Grand Prix Meeting at Donington Park in May 2004.

Leading is Frank Sytner in his 2½ litre 1963 Brabham BT4, chassis #IC-2-62, a car that was derived from the BT3 F1 car and intended for Tasman Formula Racing. The following car is the 2½ litre 1960 Lotus 18 of Michael Schryver and the third car, as far as I can make out, is the 1½ litre 1961 LDS Mk2 of Julian Wakeley.

On 27 December 2016 I showed a photograph of the Brabham BT4 in the paddock at Donington Park in May 2001.

Brabham BT4

This car took part in the HGPCA Race for Pre-1966 Rear-Engined Grand Prix Cars at the VSCC's Richard Seaman Memorial Trophies meeting at Donington Park in May 2001.

It's Frank Sytner's 1962 Brabham BT4, a Tasman car that was a development of the BT3 using a 4 cylinder 2½ litre Coventry Climax FPF engine instead of the BT3's 1½ litre V8 Coventry Climax engine. The chassis number of this car is IC-2-62.
