first time down the track advise?

so...i MAY be able to hit the track again this friday
(not set in stone yet, but i sure hope so)

i have since installed a evap can in the car, so no more worries about tank vents, and replaced the fuel pump with a high volume unit (still mechanical though)

i also swapped out to tired N50s for a set of nitto 555R 275/65-15s

now, im still running an open rear end, so do i still avoid the burn out box?
(wouldnt want one tire to get warm and grippy and steer me into a wall)

im hoping to get some better times this time around, i feel like i should be able to break into the 12s
