One of the most important things to do when setting a car up for drifting is to lock the rear diff.
There are many mods around the internet detailing different ways of doing this (using glue etc) bit I decided to just buy a replacement part to do the job.
This is a single part made to replace the differential gears in a tt01 forcing the wheels to spin at the same speed.
The differential gears are removed…
… and replaced with the part locking the differential.
