I'm selling my NM Engineering torque arm insert I had in my car since October last year. It ran for about 3.5k miles. Even after 6 months, I just couldn't get used to how much it was vibrating inside the cabin during idle (automatic transmission). So I switched it out to Powerflex yellow which seems much better even before the break in period. Asking for $40 which includes shipping.
