Focus RS mk3, trackday often in real life.
the car is really more forgiveness in real life, you can control slip angle more easy in real than GT7.
Going to SPA francorchamps in 10 days, so i can compare real life vs gt7.
what i already know, in real life i really try to avoid the track limits (tire dont'like it, risk of suspension broke etc...).
i've seen some videos on YT there +/- 5 secs between gt7 and real life depend on track.
why wan't to compare ? the break point are evolving in reality, i don't want to broke my real car, the tires, break pads cost an arm so i try to preserve it in real life etc...
GT7 is a game (really good game for me and i love it so much), try to be near a simulator (tracks and physics seems good), but really far from reality (it's not a critic), i've played online recently (last time must be on PS3 maybe ? don't remember) and with a good wheel you can have race thrill etc...
