Wait a minute. Sid? Are you playing ver2? That would also mean it's raining for this particular Usui track, right?
Yeah, what Hira said. Most are $1 a game so please don't go kill yourself after reading this.

I was in Australia for studies about 3 years ago. I guess why they keep it at $2 (all of the games are bloody expensive!!) is because most of the people who play this are the rich asians. Anyway for the Aussies, they don't mind spending this amount of money if they can have fun. Go to their casinos, you'll realise the difference as compared to Genting or Batam. Just don't gamble

For GC8V, if you're really sure of the track, use steering 1 or 2 if you want some feeling. 1 has almost no feeling and this is for dry. It's really no feeling at all if it's raining. That could explain why you felt the steering is like spoilt. But if you could pull the wheel towards you, I guess it's spoilt.
Anyway for the 1st turn, brake more but do not fully steer as you'll cause it to spin. Start braking lightly about 50m before the turn. You should be able to slide through nicely at about 155 - 160.
The 2nd turn is a bit tricky. Looks wide but you can't go too fast. Same thing as before, brake lightly before reaching the turn. Turn gently and slide through at about 170 would be alright.
One last thing, it's actually better to slow down a lot to go through the turn nicely than to speed through and crash. You really lose too much speed if you crash and usually it causes you to lose.
