So no, unless you're gunna use it in time trials, the porsche only needs R$ upgrades. You could also upgrade it so it can farm LeMans races while the Nismo is servicing, if you really wanted to. 100% series completion of EC is also not a goal in the near future.Thanks for the info regarding R$ upgrades on the 919 2015,alongwith the FU Nismo being suffiicient to open EC's 10 lapper.And you're correct that some GC upgrades might make the 919 more enjoyable at the 10 lapper,when the Nismo is servicing.
