So, I won this car from the B-Spec MR challenge. I think it is a beast to drive. Fully tuned it nets 969hp at around 1204kg. Only one problem though. After just one race the horsepower drops to 892 and the weight actually increases to 1240kg. An oil change brings me back up to fully tuned ratings. Is this happening to anyone else, or does anyone have an idea of why this is happening? I can see maybe a small amount of power loss after 1 race, but for the weight to increase? I'm thinking glitch.
