New to the drifting world and still waiting on my TT01D Type E to arrive. Wondering if I should lock the rear diff when I do the initial build or run it for a while with the stock diff to work on my driving skills before I lock it? I have done alot of reading on the different ways of locking the rear diff but have not heard anyone mention if it's a good idea to enter the drifting world with a locked diff, or to wait so you know what the change makes to the car?
