Civic Type-R TCR suffers in the endurance race as its chassis and braking are not as strong as i30N TCR. The performance will degrade sooner on the Type-R due to extensive heat and stress. It is i30N that has the highest BoP (maximum weight, weigh more than all other cars) and still won. That shows proven strong chassis / high torsion rigidity. And the Alfa Romeo has the least amount of BoP restraint as it's got lots of power and less weight, but suffers more in low speed corners.
