the biggest thing i learned, was race the track and dont race someone. the first race i realized that i won the race by 4 laps and second was 2 laps up on third. almost everyone tries to beat the other down the straight and then they go flying off the track. if someone catches you just let them by and try to follow their lines but dont push your limits. also if your faster than someone dont push the issue to pass, just sit back and wait for a good opportunity, or wait for them to wreck. i have had bad luck in my qualifiers and had to go to the B-main starting 15th and within the 15 min B-main i would be in the lead, all i do is start slow dont worry about anyone but yourself and just follow the person till the crash and they will quickly if your pushing them. and if you have a clear track push harder but dont try to pass someone in a hurry because 9 times out of 10 you will crash or both of yall will get together wrecking both.
just my 2 cents.
