hurr

hey, the physics behind a spoiler is provide downforce for high speeds as well as braking. I dont think there is much to gain from the M3 wing, the Ltw high spoiler seems to be very effective tho. you probly have 170 WHP, im not sure about torque, i think 150 to the wheels, try searching.

Well if you get the one with the break light it will usually knock off a few bills from insurance, thats what Im looking to do

[Cirno]

cool, i have intake and a chip, so i dont know waht hp i should have, but thats for the info

Take it to the track and see what it runs. I know it's not the answer you're looking for, but every car runs differently.

[camiloteram]

how much hp can u gain from intake and a chip? thats pretty much my only two options for a performance upgrade, or is there somethig else im forgeting?

[RedNosePit]

You can get a chip, intake, full exhaust, under pulley kit and weight reduction for more performance gains.

M3 cams are another option
as is a lsd and numerically higher rear end
I think there are also some FI kits for the 325, although I'm not sure onthat one
