Achiement seems to be more difficult than it really is.
But it will take some time. A total of 216 gold stars must be earned.
This is approximately 4 hours of riding without racing. Put the podcast on the background and hurrah to get going!
You must complete a lap for each of these 9 circuits:
Shaluk Sands
Palm Coast
Euro Autodrome
Stanelake Circuit
Martina d'Azur
Sakura Speedway
Circuit do Sol
Mont Vitesse
Layton Raceway
For each of its variants. There are 6 variants:
Classic/Long
Reversed
Short
Short Reversed
Shortcuts
Shorcuts Reversed
For each category of car. There are 4 categories:
N-Dura
Evo GT
Protech
Apex
The tougher races are Layton Raceway in the N-Dura category, where you have to deliver a clean run on an ideal track with ideal boost consumption.
The whole Evo GT category is a bit harder. The final boss of this achiement is a combination of this category and Layton Raceway, where you have to master the brake, throttle and boost trick. (There are a few tutorials on youtube) - But for normal racing this trick is not needed.
Tips/Tricks:
1) I recommend making a spreadsheet to keep track of your progress. The spreadsheet will then fill up quickly.
2) If you don't believe in some of the shortcuts, you don't need to use them.
3) The time to beat gold is the same for : Classic/Long, Reversed and Shorcuts Reversed.
4) Time is the same for: Short and Short Reversed
Good luck!
