drag strip prepping

[Festively Jolly]

ill be making my way to the strip in a few days so i was wondering if
there is anything i could do to get an edge on competition.  racing
fuel? i once heard that jet fuel is 108 octane or so that can be used in
a car safely. true?

maybe taking te rear seats out could reduce weight... but is it worth
the trouble?

any more advice would be awesome

o yea... car is a 1988 Audi 90 FWD
