what was the average time it took for a f1 pitstop in the 1960s also how many men were in the pitcrew.. thanks in advanced.|||Prepare to laugh.....in the early 60's and late 50's 3-4minutes. There were no pit stop garages, drivers pulled up on the side of the road, climbed out, along came the mechanics with their tools around their waists, lifted the bonnet off, did some tuning, slowly replaced the tyres, driver climbed back in and drove off. There were about three mechanics in total.
