Choose the car you want to do drift with and copy my code onto the car in the handling.meta.
Instructions are in the download.
I have included original handling.meta also for backup.

Instructions
You NEED OpenIV 2.6.
1. Open OpenIV
2. Go to update > update.rpf > common > data
3. Copy handling.meta to a folder and make sure to make a backup. (Or use the one I provided)
4a. Copy the code I gave and place it into the code of another car.
4b. This is explained in the jpg picture but go down to 'AVERAGE'
5. Now rename the handling.meta file to handling.meta if it isn't already.
6a. Then copy your modified handling.meta into the folder you got it from.
7b. Make sure to enable edit mode.

Tips:
Use my original and elegy drift handling.meta as reference if you get stuck
Or just use the elegy handling.meta if you only want the elegy drift mod.
Now you can choose any car to be a drift machine.
