Use manual transmission if you got a joypad that has 2 buttons on top or at the back.
I got a joypad with 2 buttons on the back, and i drive faster with manual transmission then with automatic, it takes sometime to get it working right, but when you do..
Shifting goes really fast, and you will have to shift a lot, but manual is much better then automatic.
The miata is 1 of the best cars in the game, and certainly is the best to begin with.
My best drift was 78k... mind you that this 1 drift, not the whole event... i was quite sweaty, and i was kinda happy that it finally stopped, because if you go against the wall with such a score hurts pretty bad.
I had a score of 250k ish totall that round, i also had 5 star rank, so i got lots of extras.
