when did Nascar start mandating the pit crews wear fire suits and helmets?
Fire mains are often 6 minimum to provide 5,000 gpm even at diminished pressure due to multiple openings. Each hydrant is capable of 1,500 gpm minimum delivery. You will have to explain your referrence to 10kg for a better answer.
very slowly u go over those big flat ones at no more than 5 miles an hour or ull start rippen **** off. and those short tall ones at a crawl. air suspension wold be ideal to raise but mostly try and avoid them all together. and if ur talking real low stuff like less than a 5 inch clearence dont try it at all.
