I play quite a bit, I have 2 cards. I drive a 86 toyota trueno ae86, and a Toyota Altezza RS200 "is300" anyways, the toyota is definitely much quicker off the line, and better on the courses with lots of turns. The 86 trueno is great on "AKINA" and "AKAGI", its actually the best car to race on AKINA's downhill course. I play a little too much lol. Anyways, what car do you drive? most people just mash on the gas pedal and try to turn and expect their car to "drift" its way throughout the corner, when actually, you have to use your brakes quite a bit.
I say about 2 seconds before you actually hit the corner where it turns sharply, slam on your brakes and let off the gas, THEN downshift and floor the gas, and your car should respond quite well. The game itself is pretty easy to play, it all depends on how you respond with your vehicle, every car is different, i can take my friends fast ass skyline with bad turning, and beat any car out there, while if i use my TRUENO i can beat the skyline anyday just because of the technique involved lol, most think its just a game... it really hooks you in man, just keep playing, you'll soon understand what i'm saying about technique and all.
