First, ignore the line they give you it sucks, the most important thing is to get the braking correct for the first corner. This is VITAL you dont want to drop below about 95kph go wide from the line to maintain more speed. After the exit try and get left as far as possible without compromising speed (should be roughly 100kph+) you will probably still be right of the yellow 'line' flick the car to the right as you enter the line into the second corner, this is probably the 2nd hardest thing to do after braking 1st, some quick controll will be needed. 100kph should be maintained throgh the corner and a time of roughly 12.8 seconds for the split time should be achived. You should have ver good momentum to push you down the straight for a gold.
This worked for me i found that if you follow the line correctly you brake too much into the first corner and you end up slow around the rest.
Hope this helps
