The same here, I have rss's tune and after playing that jump for an hour this evening I managed 550ft twice and three quarters of that hour were rewinds, even just a nudge on the stick to the left or right can add or subtract a few feet, I think it can be done but it's going to take some time and patience on the day, if you don't have the Huracan HE already then it's well worth it, if you do have the car is it worth it for a couple of million credits in the auction house, I am the latter, but I am going to still give it a dam good go.
Did all the #FORZATHONS just now also.
Nope I never got the car. Even during wheel spins. So I'm gonna get this as long as it takes!
