I've tried to collect some pictures to notice that there was some racing in Russia...
One of the first racing cars. Russo-Balt S24-55. Participate in Monte Carlo rally. 1912
Another Russo-Balt S24-55. Series III. Already totaly racing car
And then revolution came. There was no time for racing for a long time. USSR needed heavy trucks more than civil cars to build the roads, factories and so on. Besides, there was not enough money for racing.
And then WW2 began....
Pobeda-Sport, based on GAZ 21M 'Pobeda'. Sport became a national project. Pilots were usually taxi-drivers, and I think most teams were based in Taxi-parks and 'automobile-combinates' All the decisions were checked by the Party, so the bureaucracy machine was started. But nobody in the head of the Party was fond of racing so they always looked at it as it was only games....
Kharkov-6 with the 'Pobeda' engine. 1952
After the war record cars were the priority way for racing. Speed records fall one after another

Russian plants didn't manufacture any GT cars. So people had to use homemade cars like this.
