Yes the white E90 was definitely faster than me too. as i was trying to keep up, i made my best laps times. I realized he also lift off the gas at on the straight after oak tree after about 120 mph. still he was much faster.
I don't know what tires he was running but the engine seemed to be same. If i didn't let off the gas he wasn't able to close in on the straights but he was very quick thru turns
