Comparo GT3 vs F1 car
 

So you're at a track day in your Boxster and you feel good about yourself: Your times are reasonable fast, you hit the apex' right and then SUDDENLY a GT3RS passes you like you're standing still and you know where you rank in the scheme of things.

Now imagine you're in a GT3 Cup Car. You're in a race and you feel good about yourself: Your times are reasonable fast, you hit the apex' right and then SUDDENLY a F1 car passes by. That what you about to see in the next video:
Someone overlayed footage from a touring car race (with mostly GT3) and a F1 race at Eau Rouge in Spa. Absolutely amazing
