Can't get past Darius? There a few tips to help you beat him in both, Canyon and Street:
Make sure your car can go REALLY fast (I mean fast), preferably a Lamborgini Gallardo.
Set your wheels to Drift, and Suspension to Oversteer, it'll help you pass the corners
Set your NOS to Duration
City: Try to take ALL shortcuts, you'll need it to shed time off your race. Make sure to block Darius regulary, or he will pass you, but if this happens, it's time to test your Duration NOS.
Canyon: Before you start, be prepared for the challenge by training at Canyon races in Challenge Series and Quick Race (Quick Match if you can). Brake often at turns especially at the beginning. If your points are low at the 2nd leg, either try to get hit by him, or slam the accelertaor (making sure that you don't fall off), or you will lose like usual.
It takes a while, but eventually, you'll win. After that, just sit back, and relax, and watch the credits roll...Just hope your computer doesn't crash or anything or you'd have to beat Darius again
