TGK Motorsport Subframe Inserts
One of the easiest and most underrated mods for tightening up the handling on the C7 S6 and S7 is a set of subframe inserts. The factory mounts have a bit of play that you really start to notice once you push the car through corners or launch hard. I installed the TGK Motorsport Subframe Inserts on my S7 and immediately felt the difference—less rear-end wiggle, better throttle response during shifts, and overall more connected driving feel. They’re CNC machined, install without dropping the subframe, and are perfect for daily-driven cars or full builds alike.
