So is life.... Everything you worked hard for can be gone in less then a few seconds. If I'd crash my M3 somewhere on a driftevent and it's total loss... That's 3 years of hard work and spending every bit of money I had, gone. Would not say wasted because it was worth it
I however do enjoy iRacing from time to time. I dropped allot in SR due to a few bad races but it comes back as quickly if you drive good results.
They give extra cooling to the radiators. They use the same setup as most Porsches. Radiators in the front (corners of the front bumper) and engine in the back
