Okay let's get it straight.
Real life drifting has nothing to do with LFS as previously mentioned.
On public roads even in closed circuits and tracks, the tarmac has not a consistent amount of friction. One moment you're rolling on a fresh patch of tarmac, the other you're over bumps and glazed surface.
G forces move your body on the seat, your feet are heavier on the pedals during braking or cornering, your head is trying to compensate the forces too, it's WAY different. You only need to try it and see for yourself.
As for the car now, tires, wheel bearings, all suspension bushings, shafts, differential(s) and gearbox get a massive abuse. More grip you have, the worst is the stressing...
Wet weather is ideal to find an empty parking lot and try to break the rear end grip and see what's going on. You wont drift at high speed but you'll get an idea. Keep in mind, that static friction with sliding friction are far from each other.
If your budget permits, there are some pretty nice used RWD cars you can chose from, strip out the whole interior and make fun out of them in some track days.
You wont start drifting unless you learn to drive properly fast first.
You'll get to a point eventually when you can drift instinctively!
