Dont spend tokens to open labs, you can buy keys if you need to. You may need to max it and full pro tires and drivetrain. The car needs 12 mids, 8 adv and 12 v6 engines, you need half of those to get it so if you have a quarter of that the rest you'll get it from R&D boxes. I think you can win it, especially if you're a top ~500 player. A guy won it with 1625 rank so lets say you'll need to get it to 1725 to win it.
