i used to race gokarts. at the beginning of the year i was running about 1:30-1:35 on the track because of coasting. by the end of the year i was running low 50's. on that track because i would brake 5 feet before the turn going about 60mph and just slam into the apex. and at the beginning i though i was doing alright, its amazing how much time you can make up in a good corner.
