I hate to admit defeat, but I'm tapping out on trying to beat the Spa WTC 600 at 400pp. I even found a pretty OP car at 400pp, the WRX GrB slips under 400 on CH with a bit of a ballast glitch. It's the quickest 400pp car I've found around Spa, 2:56 laps while abusing the hell out of kerbs, cause that's what GrB's are great at! Still not enough because of the rubber banding at the front, the faster you go, the faster they go. A couple of examples, I tried out a stock Tundra, gift car, heavy AWD with 400 plus Hp why not. Decently fast, lapping around 3:02 so no threat to the AI, Yamanaka posts fast time on lap 2 at 3:02, cruising in the lead, a pretty typical time. Keep in mind the AI starts with 30 seconds lead in a 4 lap race. Final lap he posts a 2:56 so purple by 6 seconds, nothing too crazy. Example two; I wanted to see how fast the AI was capable of on EASY. I went full sweat mode with the WRX at 599pp and tried to bait the AI into believing I wasn't a threat. I putted around the first 2 laps maintaining a 25 second gap to the lead, if you put in a fast first lap the AI will respond on lap 2. This time Fraga, another Supra, posts a 3:02 on lap 2. Time to put the hammer down and catch him. I did at the beginning of the final lap and followed on his tail, passing him at the line. The result, his final lap time 2:46! That's purple by 16 seconds! On EASY! Impossible for me to beat in an under leveled car.
