I was used to "grift" very much in GT2, and still some in GT3. The races were between, the grip, and the speed drift. Speed drift is almost the oppose to Drift. Drift is great angles, low speed. Speed drift is low angles and great speed. The Drift King did a Drift attack (like a time attack, but with speed drift) in the "Drift Bibble" with a S14.
Speed drift is like grip, but with a little drift. I was used to have some videos of speed drift, however... I deleted them.
You call Grift a drive mode where you drift and grip. For me, by the name, I call it a technique. You enter a curve with drifting to help you hitting the apex, but then you must skip to grip at the apex, and exit the curve with grip, where you can apply all your power.
By the way a Trico Pro, I was used to speed drift in gt2 with a trueno with 130 HP, with Soft tyres at SSR5, and Rome Night. It was pretty cool.
In GT3, was a Trueno Shigeno version with 260 HP with super soft tyres. Altezzas with 450 HP, was my "breakfast" with that Trueno. lol
In GT4 I was drifting (just a day of pratice) with a Skyline, 500 HP, in normal tyres. Need to concentrate on useing the sensitive buttons of the ps2 Pad. Too much wheelspin.
In my opinion, to "really" speed drift, you need to be racing giveing all that you got. I found myself beating a Ford GT with a Trueno in GT2. lol
