Beginning on September 1st, the most competitive TBO challenge in Live For Speed returns for the third consecutive year. This series not only tests a driver's speed, but also their endurance as tyres are always a concern. In years past only those who were able to finish without stopping in pit lane have taken the checkered flag. In twelve series events over the first two seasons five different drivers have tasted victory. Sadly, in years past only the XRT has won. This is why the XRT has been moved to a two percent restriction from the previous one percent restriction.
