Formula Easter (or Forma Easter) was a single-seater, open wheel, open cockpit circuit car racing series during the 1970-1980s, specifically created for drivers from the communist bloc, driving cars created solely from parts manufactured by the COMECON industry or created from scratch as a citizens' initiative by Eastern Bloc residents. Nominally, the series belonged to FIA Formula Category 9 and Technical Group 8, although FIA only acknowledged but did not officially sanction its existence. == Technical specifics == Engine displacement was maximized at 1300 cubic centimeters, which restriction lead to widespread adoption of the Lada (Zhiguli) 21011 car's engine bloc. These soviet made inline-4 powerplants produced 70-75 hp off the assembly line, but could be tuned up to 90-110 hp with moderate effort. The Formula Easter rulebook banned any modification of carburetors, pistons or the camshaft. Better financed and well-connected teams were able to source these parts from Lada cars specifically made for Free World export markets, as those batches exhibited better workmanship and more potential for tuning. Some teams opted for engines from the Dacia 1300, Polski Fiat 125p, Skoda 105 or Wartburg 353 cars, out of pride for national representation, but these equipment were less popular in the series. Lada-sourced engines were sometimes connected to Soviet made, cast magnesium Zaporozhets ZAZ-968 car gearbox housings via custom-made, load-bearing interconnectors - which setup made it easier to access and swap out the ratio gears in the pit stop, thereby helping to alleviate the limits imposed by 4-speed push-wheel or stick shift transmissions. Suspension was usually adapted from the East German Barkas minivans and teams filled the strut legs with in-house mixed oils to enhance their performance. Half-axles often came from the soviet-made UAZ all-terrain capable jeeps and minivans. Deceleration was provided by aftermarket-drilled soviet Lada brake discs, paired with east German, four-piston Wartburg calipers. The steering assembly was often adopted from east German Trabant mini-compact cars, but required extensive customization to fit available space. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Formula Easter」の詳細全文を読む スポンサード リンク
