In August 2022, I returned home from a track day event with a broken differential and cracked rear brake rotors. I already knew that the differential was overdue, as it there was a high buildup of metallic particles in the differential fluid. With a mileage of 170.000 km (106k miles), I decided it was time to replace all other parts accessible after removing the torque tube, transmission and differential. From August 2022 to April 2024, time was spent to disassemble the drivetrain, saving up money for parts, waiting for parts to arrive and doing the actual work: Removing the drivetrain Larger 330 mm rear brakes from C6 Z51 New built 4.10 differential with C6 Z06 internals Rear engine seals, gaskets and barbell replacement Pilot bearing replacement Spec Stage 2 clutch kit with aluminium flywheel Torque tube maintenance M12 transmission extension housing oil leak Shorter rear brake lines Slave cylinder shimming and Hinson remote bleeder C6 tunnel plate upgrade Reinstalling the drivetrain
