Clunks and pops from slow turns or driveway maneuvers are a telltale sign of subframe shift, and this CNC-machined stainless steel locking collar kit provides a permanent fix. Precision-engineered insert bushings and hefty bolts work together to center the subframe and eliminate those noises while boosting chassis rigidity and handling. The kit includes application-specific upper and lower collars plus large-diameter subframe bolts that resist stripping and can be installed in about an hour.

Designed for MkII Audi TT, TTS, and TTRS models from 2008 to 2013, this upgrade addresses subframe knocking without adding extra noise, vibration, or harshness to the cabin. The reversible installation requires no permanent subframe modifications, allowing a return to stock if desired.
