If you buy the Audi R18 e-tron quattro (2015) for Endurance Champions and upgrade it to -1 Engine & Brakes (7332322) for PR 96 at a cost of 490 and R$2,070,000 as suggested in the Upgrades Strategy For 100% Completion then you can complete all events in that series except the Porsche 919 Hybrid (2015) and NISSAN GT-R LM Nismo (2015) showcase and timetrial events. This will unlock the 10 lapper for you which maximises fame / gold farming. However, in doing so you will have to skip the Porsche and Nissan showcase discounts which don't appear anywhere else so you will have to wait for a sale, flashback, LTS or pay full price for these cars.
