:whs: Since you already have a RMM and Traction bar, tires and suspension mods are all you got left, but being a torque monster we will always have SOME torque steer. Just be glad it isn't as bad as a Mazdaspeed 3 or Neon SRT4.Completely normal, tires will help that a lot also. If you are getting slight slip from the tires they are fighting each other. When my Michelin PSS are new torque steer is at a minimum but as the heat cycle and loose grip it's gets worse.
I've noticed this also, either "fight it" less and give the car a moment to fix it for you, or disable stability control (press and hold the ESC/Sport mode button for 3 seconds) and fight it manually yourself without the cars help.The "weave" comes from you trying to counter the torque steer before the car does. This adds up to overcompensation and you end up "weaving". A tight grip and learning to manually compensate less reduces this.
That's my biggest problem, there will be lines, cracks or raised filled spots and when you roll over them your car will follow them like it's on rails...The problem I have with MI asphalt roads are the stupid ruts...It's like riding waves
