A bit of explaining.
1) Mentioned Camaro features beefed-up suspension, larger tires on back, positraction, some aftermarket 2-speed (!) tranny, non-power steering and minor engine mods like aluminum intake etc.
2) Mentioned race take place in Moscow
3) There was article in local tuner magazine about two mid '70 Camaros also placed in Moscow, which says, that they can't fight against anything modern.
