i'm having a hard time reading your english but if i understand correctly, you're having trouble with the first turn on akagi downhill. dude, there's one thing you should do - use the brakes. releasing the gas isn't enough (i'd like to think this is true for most of the turns on all courses except myogi)
the course is downhill and you're going as fast as 140+km/h when you get to the turn. if you don't step on the brakes, the momentum would take the car straight to the railing.
if you watched and listened to the first episodes of the series, it's explained that racing isn't just about speed and taking the right line but it's also about weight transfer.
when a car accelerates, it's entire weight shifts to the rear. that's why even real racers use the brakes because if they don't, they'd either hit the rail or go off the track. you need to use the brakes to balance the weight of the car, go as fast as you can while still taking the correct racing line. when you can do that, you'll know if you need to use the brakes or not.

the R32 and R34 is the strongest on myogi, with a top speed of 207km/h ^^
the sil-eighty is the strongest on usui but the 180sx and s13 are pretty good on usui too ^^
the ER34 is pretty good on akagi as well ^^
the GT4 may be the best for akina snow but the R32 is good for this course as well. with its weight, it grips the road better than most 4WD cars ^^ (my friend and i even tried the DC2 on this course and it it did surprisingly well

)
the EK9 is best for happo outbound, the EG6 for inbound - but the MR2 and MR-s are pretty good on this course as well
@Bunta Legend
actually tsuchisaka is home to most 4WD cars (particularly the evos) but yes, the evo5 is "strongest" on tsuchisaka ^^
