## Customer Reviews

### ⭐⭐⭐ Good product, poorly packaged
*by N***S on June 30, 2023*

Precision machine rotors were packed in individual boxes placed end to end, tearing boxes, allowing outside diameters to bang against each other, causing minor damage.

### ⭐ 1996 4x4 chevy 1500
*by A***R on November 17, 2024*

Was only 5lug still waiting to getreimbursed for returning parts.
