Ok, ok, i know people are going to spam about how the M3 has enough power, and that mods are going to be too expensive, but anyways... If you (M3 owners) were going to do power increasing mods, what would you do? Would you do a Dinan S2? Would you GruppeM intake, or hamman kit your car? Would you wait for Dinan's F/I? Any replies or other mod companies (other than hamman, dinan, gruppem, eisenman, supersprint) please list them. Thanks in advance for replies.
