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

yep! just put the rear in (got it for a grand, he even through in the DS)


the car is a DD so im prob ganna go with nittos and a good solid clutch once mine go, but i dont have the funds to just throw money at the car anymore

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?

^ you also have a good 150hp on me lmao, well what is every ones prediction on my 1/4 mile time? keep in mind its my first time to the track with all the above stated- my goal is to get into the 12s with a trap of 112+

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
