I've tried quite a few GT40 MK1 tunes and this is the first one that I could classify better than just "good", for me. Acceleration and grip is fantastic. The rear-end does what you tell it to do with the throttle and the car really does move. I took it around Nuburgring GP/D and set the 2nd fastest lap, for me, on that track only doing two laps in this thing. I can't wait to see how she performs once I really get to know her inside and out. A really easy car to drive too. Would recommend to beginners and experts alike.
