Very good!!!
Not to try and contradict what others are saying about the Hp and speed, but I think that your speed was just fine, and you seem to have a good handle on that kind of power. Just a little refinement is needed so you don't go off track into the kitty litter.
Don't get me wrong, I like stock-on-SIMs drifting....It does the job, looks fantastic, and gives me the ability to fine-tune my car control. However, there is nothing like high Hp drifting IMHO. The R34 in my vids are 1072 Hp, and most of my drifts are 70+ mph entering the corner......I just hide my speedometer, wheel and tach during my replays, just to cut down the critisim that is so prevolant around here.
If you can drift with minimal tuning, and KNOW how to handle a high Hp vehicle, you can find your balance. I see nothing wrong with that.....Keep it up!!!!
I look forward to more vids from you to further demonstrate your skill....Good Job!!!
