Default how to launch my car: street tires

itll be my first day out so ill need all the help i can get

performance wise its full bolt ons minus ls6 intake- if you want details i will post them

its an M6 with stock clutch, BFG sports, 12 bolt with 4.11s, SLP tQ arm, lcas, 21mm sway bar, and hopefully my SFCs will be welded in

the car made 325/342 thought the 10 bolt when i had it... i havent had a chance to REALLY play with the 12 bolt so no idea where my sweet spots are yet

want to get to the track this weekend or next

you launch it very carefully haha 4.10's and street tires are not a good mix ..... trial and error just start at 2000 and see how the car acts, and have your tire pressure at like 25 ish

ya i figured 25psi would be good, with the 3.42 i found best luck (on the street) launching from ~2400, will 4.11s really hinder my launch that much without DRs?

well i figure the car should run mid-low 12s (with a perfect launch on DRs) since its my first time out on street tires, will 12.9x and 112 trap be possible? thats what i was trying to get at
