So DarwinAce, what you've said in your third paragraph is basically this: "Drifting is a good racing technique, the proof being that I did it once by accident and prevented someone from passing me." I can't say that's very convincing
Even with default setups I doubt very much that someone getting sideways would beat someone taking smooth lines through each turn. You can't kick the back out and block someone at every corner - sooner or later you'll need to think about your lines and try and be smoother in and out of turns. If a guy's a smoother driver than you, he'll pass you somewhere. If he backs off a bit and brakes a little earlier than normal (but not as hard), takes a slower line than you into a turn while you scrub speed off by drifting in hot, he'll be set up for a better exit and be right on your rear to catch your slipstream down the straight, or pull up next to you coming into the next corner.
Every time I've raced and gone into a corner sideways by mistake it's cost me time and made the job of the guy chasing me easier (if he's smart it has). I get passed a lot so that's fine, but losing traction only hastens the inevitable
Getting sideways in any car has never benefited my laptimes or my race results.
Drifting can be useful on some occasions, but not for a whole race - not one longer than about 5 laps anyway - and certainly not in a GTR with a decent, even conservative setup. The way the FZ GTR eats tyres, drifting will not do you any favours. Some 4-wheel drift (not the same as arse-out sideways drifting) can help keep your corner speed up, but with LFS's GTRs and their slicks and wings, it isn't necessary. They're designed to have maximum grip and driving them any other way will not benefit the driver in the long run. The LX cars, however, can benefit from a slight loss of traction on all four wheels, but they have no downforce or slick tyres and some 4-wheel drift through a fast bend can mean the difference between front row and 3rd row on the grid. I do mean "slight" though...getting all fishy with an LX is not recommended
OK, next, your description of braking - "losing speed wastefully" - is utterly backwards. If I come into a corner sideways, my tyres are sliding across the tarmac, generating a lot of friction and therefore heat. The heat being generated is surplus to my needs and just dissipates into the air, so it's heating up my tyres for no reason at all. It's basically wasted energy. But if I use the brakes and keep the car straight, the heat's dissipating off of my brakes and my tyres are maintaining their temperature as I go through the bend. If I keep my exit clean and don't spin my wheels, my tyres aren't getting hotter than they should be. You might be able to block me here and there with some drift, but all I really need to do is what I said earlier: brake a little earlier, enter smoothly, get a good exit and get you later on
More accurately, I'd say the
ability to drift is a good thing to have in your racing skill-set as it means you'll be able to save yourself when you have an unintended loss of traction or if you enter a corner way too hot.
And for crying out loud stop calling it "grip driving"
On tarmac tracks, racing pretty much implies grip, as without it you're not going to be very fast, in any car
