Thank you ultimatecar.com

Lap times:
Laguna Seca: RL. 2:13. (Flying lap). My best time. 1:49.2

No TCS OR ABS OR STM.

I wonder if that massive lap time difference has something to do with the limiter? Not that on laguna seca it has that much of an opportunity to go so much faster than 124…
What tires are you using?

I leave the car stock when I compare them to real life stats
