Drift handling problems

[Mooozart 0]

What am i doing wrong when adding a drift handling?

From beginning: i install the car using GTA IV Vehicle mod installer, then i go to handling.dat, goes to the car i modded and paste the new handling over the current handling then save, update and start gta iv.

Now when i spawning the car and driving it, it is like it got low gravity, when i turn the car it flips (or almost), there is no drifting at all X_X

Nevermind, i solved it myself it was the trainer somehow.
