if your not doing burnout,which you dont really need to on street tyres---drive around the water,driving through it could only hurt your launch.
raise rear tyre pressures to max recommended on sidewall of tyre,fronts about 20psi for street tyres,strip any easy dead weight you can get out ie-subwoofer,spare tyre etc etc.....
dont just dump the clutch and keep your accelerator pinned down,slip the clutch !slightly! around 3/4 throttle then when you feel the car has momentem and is reaching full traction after 0.?? seconds flatten the accelerator.
when you pull into stage,get it so your front tyres only just roll onto the leading edge of the stage line and your light comes on,gives you 10cm or so before you cross the start line (hey it all helps ok lol)
if you wanna go all out and have camber adjustment then you want your fronts dead straight to get more traction - probably getting a bit too hardcore though
