What's the best way to tackle the p-mar tunnel, I know it's possible to take without slowing down, I've seen it in replays. But I can't for the life of me find a good angle, either I cut through it but cant turn in time and hit the outside of the 90 at the exit or I hit one of the inside curves of the tunnel and just have to live with it.
I can perfect lap the other tracks but p-mar filters me. (Opposite breaking might be the answer but im shit at that too.)
