The final race is I am the law. I spent around an hour trying to earn this. I recommend either a fully upgraded Ferrari F40 or Aventador. The Hurracan really struggled at high speeds compared to those two.
Tuning your car.
Obviously you'll want and need grip but not to much or your speed will be affected. I would say set the bar half way.
The best tip I can give which made a massive improvement for me, adjust nitro so the slider is fully set on power. This will really help you power around those tight corners and blitz past your opponent.
The key to winning this track is finding the right balance so that your car can handle the tight bends at high speed but more importantly can capitalise on the long straights.
I was trailing my opposition until near the end so don't give up half way.
avoid Stinger after checkpoint 47 this is instant race killer
Unfortunately there is no quick fix or easy method. This is a tough race and on top of that you need luck, as you also have to weave around traffic.
